Hello.
Sometimes it happens that a laptop or computer does not turn on, and information from its disk is needed for work. Well, or you have an old hard drive lying "idle" and which would be quite nice to make a portable external drive.
In this short article, I want to focus on special "adapters" that allow you to connect SATA drives to a regular port Computer USB or laptop.
1) The article will only consider modern drives. They all support the SATA interface.
2) "Adapter" for connecting the disk to USB port- BOX is correctly called (this is how it will be called further in the article).
How to connect laptop SATA HDD/SSD drive to USB (2.5 inch drive)
Drives from laptops are smaller than those from PCs (2.5 inches, on PCs 3.5 inches). As a rule, BOX (translated as "box") for them comes without an external power source with 2 ports for connecting to USB (the so-called "pigtail". Connect the drive, preferably to two USB ports, despite the fact that it will work if you connect it to only one).
What to look for when buying:
1) The BOX itself can be with a plastic or metal case (you can choose any, because in the event of a fall, even if the case itself does not suffer, the disk will suffer. So the case will save far from all cases ...);
2) In addition, when choosing, pay attention to the connection interface: USB 2.0 and USB 3.0 can provide completely different speeds. By the way, for example, BOX with USB support 2.0 when copying (or reading) information - will allow you to work at a speed of no more than ~ 30 MB / s;
3) And one more important point is the thickness for which the BOX is designed. The fact is that 2.5 disks for laptops can have different thicknesses: 9.5 mm, 7 mm, etc. If you buy a BOX for the slim version, then for sure you will not be able to install a 9.5 mm disk in it!
BOX usually disassembles fairly quickly and easily. As a rule, 1-2 latches or screws hold it. A typical BOX for connecting SATA drives to USB 2.0 is shown in fig. one.
Rice. 1. Installing a disc in the BOX
When assembled, such a BOX is no different from the usual external hard disk. It is also easy to carry and use for quick exchange information. By the way, on such disks it is also convenient to store backups, which are usually not needed, but in which case they can save a lot of nerve cells 🙂
Rice. 2. When assembled, the HDD is no different from a regular external drive
Connecting 3.5 drives (from a computer) to a USB port
These discs are slightly larger than 2.5 inches. USB power is not enough to connect them, so they come with an additional adapter. The principle of choosing a BOX and its operation is similar to the first type (see above).
By the way, it is worth noting that a 2.5-inch drive can usually be connected to such a BOX (that is, many of these models are universal).
Also, one more thing: manufacturers often do not make any box for such disks at all - that is, you simply connect the disk to cables, and it works (which is logical in principle - such disks can hardly be called portable, which means that the box itself is usually not required).
All sections of the site site
All problems with hard drives(screws) can be divided into two groups: incorrect connection (which, of course, is not a malfunction) and a malfunction of the device itself (failure of the electronics and / or the disks themselves).
It often happens that everything works fine until you connect a second HDD . After that, the system "does not see" both disks or "does not see" the second disk.
Or did you go to a friend with your hard drive(screw), everything worked fine for him, and when you came home, you found that the system “does not see” your disk.
These are all symptoms of a bad connection. hard drive. There is nothing complicated in connecting a hard drive, so each user should know how hard drives are connected to a computer.
It's like being able to change a car tire. Do not call a tow truck if a tire is punctured.
HDD interface
For connecting a hard drive to a computer one of three interfaces can be used:
IDE (Integrated Device Electronics) - developed in 1986 and still in use today;
SCSI (Small Computer Systems Interface) - also developed in 1986 and is still in use today;
Serial ATA (Advanced Technology Attachment) - developed in 2003, is steadily gaining momentum.
In addition to these interfaces for connecting hard drives ST and ESDI interfaces used to be used, but the former was forgotten in 1989, and the latter in 1991.
Initially, the IDE was developed only as an interface for connecting hard drives. Later it was modified and received the official name ATA - an extended interface for connecting drives.
The difference between ATA and IDE is that you can connect to ATA not only hard drives but also CD/DVD drives.
The ATA interface has been constantly improved, and at the moment there are several of its varieties, designed in the form of standards (Table 4.1).
Table 4.1. ATA standards
Yes, the latest version of ATA was released in 2001. It seems that in the future the interface will not develop, but will peacefully live out its own. The next adopted standard, ATA-8 (2004), already describes SATAII, not IDE (ATA).
The SCSI interface is a high-performance interface for connecting various kinds of devices. Using this interface, not only drives, but also peripherals.
For example, there are SCSI scanners that are much faster than scanners work connected to the parallel LPT port. But with the advent USB bus there was no need to produce peripheral devices with SCSI interface - USB is much more convenient.
Therefore, now the SCSI interface is used mainly on servers - ordinary users, as a rule, do not buy SCSI drives because of their high cost. And a motherboard with a SCSI controller is quite expensive (compared to conventional motherboards).
The SATA interface (Serial ATA, serial ATA) was developed in 2000, but it was not until 2003 that it first appeared in off-the-shelf systems. Compared to conventional ATA (sometimes referred to as PATA - Parallel ATA - Parallel ATA), it provides better performance. A lot also depends on what the real cache memory of hard drives is.
The ATA interface is described in the ATA-7 (in parallel with conventional ATA) and ATA-8 standards. The ATA-7 interface version supports 150 Mb/s, while ATA-8 supports 200 Mb/s. As you can see, even the very first version of SATA is faster than the most latest version PATA. And SATAII is even faster.
So far, 200 Mb / s is the limit for a home / office computer, that is, for a workstation. But the data transfer rate according to the modern SCSI interface(Fast-320DT technology) is 640 Mb/s.
But such interfaces are used only on high-performance servers - most ordinary users cannot afford them, and there is no need for such speed.
Physical connection of the hard drive
As we know, there are two types of hard drives: ATA (IDE) and SATA (Serial ATA). The first disks are more “ancient”, but nevertheless there are second ones on sale - more modern, promising and faster.
Definitely - the future for SATA. It seems to me that in a few years ATA disks will be discontinued. I think so. Wait and see.
Attention! Any change in the physical configuration of hard drives and other disk drives requires turning off the power of the computer!
Connecting an ATA disk (IDE)
As a rule, on motherboard there are two controllers for connecting IDE drives - primary and secondary. Two IDE devices can be connected to each controller. I don't specifically say "two hard drives" because CD/DVD drives can be connected to the IDE controller.
The first device connected to the controller is called the master. This master device, so you need to choose a faster device for the role of the master.
The second device is called a slave. So, there can be four (maximum) IDE devices in the system:
primary master (primary master);
primary slave (primary slave);
secondary master (secondary master) - the second controller;
secondary slave - the second controller.
Open the computer cover. Typically, the first controller is labeled IDE0, and the second one is labeled IDE1 (that is, the numbering starts from zero). If you already have an IDE drive installed (because you might have bought a computer with a SATA drive), then it will be connected to the first controller.
How to distinguish an IDE connector from a SATA connector? It's very simple: the IDE connector is large (Fig. 4.3), and the SATA connector is small (Fig. 4.4).
Rice. 4.3. IDE connectors on the motherboard
Pay attention to the color of the IDE cable that connects the motherboard and the hard drive. If it is grey, then it is better to change it to yellow - these are higher-performance cables (your hard drive will work faster if you connect it with a yellow cable).
You can watch a visual video tutorial - the subtleties and nuances of
checking the hard drive in the HDD Scan program
The difference is that the old (gray) cables have 40 pins, and the new (yellow) cables have 80. When you connect the drive using the old cable, the BIOS warns you that you are using a 40-pin cable (40 pin) instead of an 80-pin one ( 80pin).
Rice. 4.4. SATA connectors
Connect one end of the IDE cable to the IDE connector on the motherboard (don't worry - you won't plug it in wrong, because the key won't allow it), and the other end to the hard drive.
And here the most interesting begins. You have connected the hard drive to one of the controllers, but now you need to select its mode - master or slave.
Next to the connector for connecting the IDE-cable on the hard drive there will be a connector for selecting the operating mode. The operating mode is selected using a jumper (Fig. 4.5), which must be set to one of the positions corresponding to one or another operating mode.
Mode map work hard disk is drawn on the hard disk itself - on the label on top. Sometimes the master is called DEVICE 0 (Figure 4.6) and the slave is called DEVICE 1. Don't let that confuse you.
Please note: Two masters or two slaves cannot be connected to the same controller. If a device is connected to the controller, you need to disconnect it and check the operating mode - if master, then connect the second device as a slave, or vice versa.
Rice. 4.5. Connecting an IDE Device
It is undesirable to change the operating mode of already installed devices. Now I will explain why. Let's assume that a hard drive is connected to the first controller as a master - Windows boots from it.
If you install new hard disk as a master, and make the old one a slave, then the computer will try to boot Windows from the new hard drive and, of course, it will fail!
Usually there is a third mode of operation of an IDE device - cable selection (CABLE SELECT). In this mode, the device will be master or slave, depending on how it is connected to the loop - to the middle or to the end of the loop. You do not need to select this mode, otherwise the controller may have two masters or two slaves (if you connect them incorrectly).
So, we connected the IDE cable, selected the operating mode, it remains to connect the power. With this, everything is simple: a lot of power cables come out of the power supply, connect one of them to the hard drive. Do not be afraid - you will not connect it incorrectly. Usually, when you connect the power, the yellow wire is facing you.
General scheme connecting an IDE device (yes, devices, since CD / DVD drives are connected in the same way) is shown in fig. 4.5.
Why didn't we talk about the location of the device in the computer case? I remember an acquaintance from America came and brought his computer with him, or rather, one system unit.
It was the system unit of the so-called white assembly. When I opened it, I was pleasantly surprised - the length of all the wires was adjusted to a millimeter. There was an air intake from the fan to the processor, the second fan was directed to the IDE devices - for optimal cooling.
Our computers are the so-called yellow assembly. Although they are assembled from us, all components, including cases, are made in Taiwan (hence the name of the assembly - yellow).
And with Taiwanese cases, the situation is such that hard drives have to be placed not where you want or need in terms of cooling, but where they fit. I'm not talking about adjusting the length of the wires. I am silent about this...
Connecting a SATA hard drive
Now let's talk about SATA drives. Connecting a SATA drive is easy. But your motherboard must have a SATA connector (see Figure 4.4). All modern motherboards have it. Don't worry, you won't mix it up: the SATA cable cannot be connected to any other connector on the motherboard.
Connecting a SATA drive is easier than an IDE one:
SATA cable has two identical connectors - at the ends. One end connects to the motherboard, the other to the hard drive. It is impossible to connect the SATA connector incorrectly - the key will not allow;
The SATA drive has no jumpers (jumpers), so you do not need to select the device operating mode;
Only one drive can be connected to one SATA connector;
Jumpers on existing IDE devices have no effect on SATA drives;
After connecting the SATA cable, don't forget to power on the SATA drive. Please note: You need a special power cable (3.3V) that comes with the hard drive.
Sometimes an adapter is supplied that allows you to connect a regular power cable to a SATA drive (Fig. 4.7).
Rice. 4.7. SATA power cable with adapter (left) and interface cable SATA (right)
As you can see, the physical connection of a SATA drive is simple. If you want to install Windows on a SATA drive, then you need to make it bootable.
How? When the computer boots up, when you see the inscription, press DEL to enter SETUP, then among the settings of the SETUP program, find one called Boot Sequence or boot device priority.

hard drive to computer | Connecting a hard drive)
The production of hard drives does not stand still. Technologies are actively developing: the speed of writing and reading is growing, the service life is increasing, new standards and form factors are appearing, which is why many old devices become incompatible with modern computers. Using IDE SATA adapters, you can even make an old machine work with new drives.
Differences between SATA and IDE
IDE (ATA) - a parallel interface for connecting drives or optical drives to the motherboard. Old standard from the 1990s. IDE technology uses a 40-pin connector to connect to the motherboard and a separate 4-pin power supply. Currently almost obsolete class. The exception is old equipment, which is still in operation for unknown reasons.
SATA is a serial communication interface. Now used in all new devices. It has a number of advantages over the old system.
The main advantages of SATA:
- high speed of reading/writing information;
- increased volume of the drive itself;
- the ability to connect devices without restarting the system.
There is also a more recent variety - eSATA. The same SATA, but guarantees stable contact throughout the entire operation time. Applies to external HDDs.
Why is an adapter needed?
There are several problems that can make you want to buy an IDE SATA adapter. For example, at home lies old hard an 80 GB IDE drive, and you suddenly need to "pull" a photo out of it. Connecting it to a new computer with SATA connectors will not work.
- On the computer, there was a sharp lack of memory, and at hand was IDE hard a disk of the required volume, which at first glance is useless.
- The situation can be reversed: without an upgrade to IDE interface ah, I want to get more extra memory or restore files.
All situations have one solution - use a SATA / IDE or IDE SATA adapter. It is able to convert the data stream from one system to another, thus blurring the boundaries between different standards. The complexity of the application is nothing more than using an adapter for microSD cards.
How to choose?
The first step is to decide which adapter is needed. There are as many as five options:
- IDE/SATA.
- SATA/IDE.
- IDE USB.
- SATA USB.
- IDE SATA USB.
The first two points are suitable for indoor installation. They will be useful if you want to place one or more hard drives or SSDs of different standards in a computer case. Usually these adapters do not even have a case and are not protected in any way. They look like a regular board, where it is intuitively clear where and what to connect.
An important parameter adapter from IDE to SATA is the speed of reading and transferring information. In case of USB adapter, it could be 2.0 or 3.0 version. The latter allows you to operate information faster, but depends on the version of the computer's ports, as well as on the capabilities of the hard drive itself.
IDE SATA with USB output
In addition to adapters for switching between IDE SATA standards, IDE SATA USB adapters can be found on the shelves. This device allows you to connect any hard drives directly to the USB port, regardless of standards. So, it is allowed to use ordinary ones as a large flash drive. This is more useful for laptops or tablets.
Meet as universal (SATA IDE adapter on one board, connection of several media of one or different type), and separate (only SATA or IDE) adapters. The choice depends on specific needs and price. An important parameter when choosing will be the presence of a built-in or additional power supply. Without it, the adapter will cost a little less, but will be less functional. It is possible to use the computer's central power supply, but this is not always convenient, and besides, you have to unscrew the cover every time.
Nutrition
IDE series drives are powered by a regular Molex connector with 12v and 5v outputs. It is on all power supplies.
SATA drives require connection for 12v, 5v and 3.3v boards. To do this, you can find a regular SATA IDE power adapter for 15 pins with a Molex connector. The problem is that the standard Molex does not have a 3.3v wire, which means that it is not able to power some board block. This feature has been taken into account by disk manufacturers and has been resolved to some extent.
Connected via a drive powered by a Molex/Sata adapter will work adequately on all machines, but may not support hot plug technology on all machines (removing or attaching to the system during operation). Most modern power supplies have a separate output - a SATA connector, which does not apply to Molex and includes 3.3v power. One way or another, modern SATA devices do not require 3.3v voltage to work.
Adapter or new drive?
There is no definite answer to this question. It all depends on your preferences and budget. At the present time, memory prices have dropped significantly, but still do not please at some points. Perhaps a more rational solution would be to purchase a new drive or docking station, which will allow you to quickly connect hard drives of different formats like a flash drive.
It is worth considering that buying a new hard drive may entail an upgrade of the entire system, while installing an adapter does not oblige you to anything.
Do it yourself
Most useful electronic devices can be assembled for as little as a few dollars by hand, with little electronics knowledge, but an IDE SATA adapter hardly falls into the category of easy-to-play devices. Ultimately, most likely, much more time and money will be spent than in the case of buying a ready-made adapter, although it is easy to find many working circuits on the Internet. But "technomonsters" should like this task.
Computer technology has long ceased to be a curiosity, almost everyone has it in stock. Only the nature of use differs: some users actively exploit the equipment by uploading films, games and music to it, while others use an electronic computer when they want to view the latest news on the World Wide Web or do part of home work.
At certain times, it is necessary to replace obsolete components
In this regard, the level of loading of the hard disk is also different. If there is very little free space left, then you should not expect normal performance from a PC at all. Given such circumstances, many owners decide to purchase a second "screw", thereby increasing disk space. However, it is very important to first find out how to connect a hard drive to a computer.
Finding information on the Internet on how to connect a hard drive to a computer is not difficult. It is only important to carefully read all the recommendations, and then there will be no problems if the user installs an additional hard drive on his own, while leaving the old one in the same place.
The old hard drive is subject to removal only in the event that it has completely become unusable and cannot be restored. By installing a second hard drive along with the old one, the user gets extended space, thanks to which all actions will be performed faster.
Installation in a PC case
Connecting a hard drive to a computer begins with the step when the user must first place it in the case and securely fasten it.
To ensure that the “screw” is inserted correctly, you must first remove the cover from the system unit case. In the front, you can easily find special baysdesigned for drives and hard drives. Drives are located at the top, and the second hard drive should be identified at the bottom of such bays.
The hard drive is inserted into any free compartment, but preferably on short distance from what already exists. This is very important, because during operation they both heat up, which will adversely affect the performance of the PC.
Then the second hard drive is inserted strictly along the guides so that the connectors are directed towards the inside of the system unit in order to ensure its comfortable connection in the future. When the new hard drive has taken its correct position, it should be securely fastened by tightening the screws on both sides, ensuring a tight connection with the compartment.
After fixing, you should check the strength by trying to loosen it. If the hard drive is not subject to staggering, then all the actions were performed correctly.
Connecting with loops
After successfully connecting the second hard drive to the computer, you can proceed to the second part of such important steps. At this stage, you should directly connect the second hard drive with motherboard and provide power to it.
To do this, you will need to purchase additional loops. By the way, it is worth noting that the connectors through which the hard drive is directly connected may differ, depending on the year of manufacture of the PC.
The old computer is equipped with IDE connectors, while the new one already has SATA connectors, which are characterized by amazing speed. Previously, users were oriented when making a purchase to pay attention to the connectors and purchase only a hard drive with the right kind. It's hard to find an IDE hard drive for sale these days, but that doesn't mean there's no hope of installing a second drive. Just in this case the user must additionally purchase special adapters.
By connecting a second hard drive using SATA connectors and adapters, the owner of a smart machine not only ensures system performance, but also facilitates the installation process.
When installing an old hard drive with an IDE connector a few years ago, I had to manually configure the “screws” mode of operation, which consisted of setting jumpers to certain positions.
Connecting using SATA connectors is much easier. All connectors on the new technology are equipped with special partitions, so it is a priori impossible to connect the second hard drive incorrectly.
USB connection
There is one more alternative way, which provides an absolutely easy connection of a new disk space, while completely eliminating the need to disassemble the system unit case.
In this regard, many people want to know how to connect an additional hard drive to a computer without experiencing any additional difficulties. The answer is obvious, the second hard "screw" can be connected to an electronic computer using a USB device.
Such hard drives are powered through the USB connector to which it is directly connected. However, this is typical only for disks having a size of 1.8 or 2.5 inches. More powerful ones, for example, starting from 3.5 inches, already need an additional power supply.
External devices are very easy to connect, so they are preferred by a large number of users.
Defining Devices in the BIOS
Having provided correct connection hard drive, you should make sure that it is displayed correctly in the BIOS, otherwise it will be simply stupid to dream of high-quality work.
To produce correct settings in the BIOS, you should also understand how to connect an old hard drive to a computer, how to connect a new hard drive, how to ensure the correct operation of these two drives.
The user understands that the operating system is installed on one of the disk spaces, in most cases it is the old hard drive that is the place where the operating system was once loaded.
In this regard, in BIOS settings the user must set the boot priority from the old hard drive. Erroneously setting the priority will not allow the system to boot. It is quite easy to determine the priority in the BIOS, since SATA with the assigned number will be written opposite the available hard drives. It is the number that indicates the priority. The hard drive with the operating system must be set to SATA 1.
If any hard disk is not displayed in the BIOS, you should double-check the connection, otherwise you will not be able to use the installed disk space.
So, installing an additional hard drive is a predictable act, accompanied by actions that can easily be performed by any user if he makes an effort and shows increased attention.
Hello, friends. Sooner or later the disk space runs out. We constantly clog our devices with data and one day we find out that there is no more space on our disk. And I want it to be always there. Today I will tell you how you can quickly deal with this problem. In today's article, we will connect the hard drive to the computer ourselves.
So, friends, you have found that you have a problem, but do not worry, connecting the HDD is actually simple. In a typical computer, one to six hard drives are installed. You can make a place to store files out of them, you can install another operating system. For example, on one disk you have Windows 10, and on the other Windows 7. When necessary, you boot from the "seven", and when not, from the "tens" - you can do that. And you can make RAID arrays if necessary.
We connect a hard drive 3.5 from a laptop to a computer via a USB adapter
The easiest and hassle-free option is to buy an external portable hard drive. Such a disk is connected via a USB connector and used as big flash drive. The advantages of such a solution is that you can store a lot of things on it? it is easy to connect to a computer, compact and easy to carry. There are also disadvantages:
- the presence of a cord that must be connected all the time;
- speed read-write lower than that of a disk connected in the usual way;
- special sensitivity to blows, falls.
What does a laptop drive have to do with it? Inside this case is the most common hard drive from a laptop. And if you have such a used disk from a laptop, you can make it portable yourself. The most main part is an adapter. You can buy an adapter in a store, taking a disk with you, and the seller will pick up an adapter for you, and perhaps even a beautiful case. Putting everything together we get a portable drive:
It can now be connected to a USB port. Or this option, without an adapter, just the connector is screwed to the case, into which the hard drive is then inserted. The case itself can be fixed in the basket of the system unit with screws:
This option is suitable for connecting an HDD without an adapter - inside the system unit. Read on.
Connecting an HDD without an adapter at home
The same 3.5 hard drive can be easily connected by yourself. You will need an additional SATA cable for the hard drive and possibly an additional power plug (if there are not enough connectors on the power supply). On sale there are such cable options where all in one:
We open the system unit after disconnecting all the wires from it, unscrew the screws:
... remove the cover,
Connect data cable to motherboard...
...and the hard drive along with the power connector:
It is highly desirable that the 3.5 disk not hang on wires. If possible, it is better to fix it in a stationary state in order to avoid vibrations and shocks.
Then, we find a suitable place for it and fix it, if possible, with regular fixing screws in a basket, or at worst with sanitary tape, so that our disk is firmly and immovably fixed. We put the cover of the system unit in place.
How to connect a second, additional hard drive to a computer via a SATA connector
If you have a standard hard drive from your computer, you can just as easily connect it as a second drive. We do everything in the same way. First, we fix the new disk with standard screws on both sides in the disk basket so that there are no vibrations:
Then we connect the cable and the power connector. The disk is connected.
Connecting an IDE hard drive to the motherboard and SATA connector
If your computer's motherboard has connectors for connecting an IDE hard drive, you can try connecting such a drive. On the IDE interface for a long time all computers worked like this until 2005. A disk with such an interface looks like this:
The connection socket looks like this:
Sometimes the connectors are multi-colored. And the cable for connecting to the motherboard looks like this:
The blue block is connected to the motherboard, the black one (the top one) is connected to the hard drive, the white one is connected to the DVD drive.
There is an important point when using IDE drives. If you are going to use such a disk, you need to correctly switch the jumper to the position Master or slave. This option tells the system what role this drive will play. Master- this disk is considered the main one, it will be loaded from it. slave secondary disk.
Different manufacturers have their own jumper pinouts. The decoding of the switching modes is always indicated on the disk case:
By setting the jumpers to a certain position, we indicate priorities - which drive is the main one. Previously, when there were several such disks, it took a long time to switch them. The SATA interface is devoid of these shortcomings. The IDE interface has long been outdated, and is no longer used on modern devices. However, you can connect your existing IDE drive to a SATA socket on your motherboard using a special adapter. You need to connect the adapter to the IDE drive:
... and the SATA cable and power cable to the motherboard and power supply. In this way, you can increase disk space by some, albeit small (by modern standards) value. More than a flash drive!
If you bought a new hard drive, it must be initialized before use, otherwise Windows will not see it, even if it is properly connected. This is done using special programs type Acronis Disk Director 12. First, install the disk in the system unit, connect it, boot Acronis Disk Director:
You will not see a new connected drive from under Windows at first. However, if in your Windows versions If the Disk Management snap-in is available, you can try to initialize the connected disk through this snap-in. In the photo, we first went to "Computer Management, then to" Disk Management ".
However, I always use Acronis, it is guaranteed to see all the drives connected to the computer.
Need to choose desired disk, right click mouse to call up the menu, select "Initialize disk", and then at the very top click "Apply pending operations":
After initialization, we create a partition or partitions on the disk, formatting them in file system NTFS. On this, the operation of connecting the disk to the computer can be considered completely completed. We connected it physically and programmatically. After these steps, the disks can be used for their intended purpose - to install an operating system or make volumes out of them to store your data.
If you decide to install another operating system on a new disk, then after installation, when you boot your computer, you will need to select the disk on which you installed it. This is done through the BIOS. To enter the BIOS, first press the key DEL, and then select the desired disk:
I repeat, you need to select from the list that appears, the disk that you need. You can then change the download at any time. In general, you can connect a hard drive yourself very easily, try everything you will definitely succeed.
