The external hard disk is connected via USB. If the computer does not see an external hard drive

Almost every computer users came across the situation when an external carrier was acquired, the computer does not see the external hDD. Sometimes the interaction and with the carrier, which already worked with PCs. To solve this problem, there are many ways.

This is a useful device that allows you to store and communicate with computers. The volume of the device may be different, a maximum of up to several terabytes. The device allows for a long time to safely store various information.

Why PC does not see an external hard drive

If the laptop does not see an external hard disk, you should use a specific algorithm of actions. First in the control panel should be found "System settings" and "Administration". It is there that you can see the section "Control".

It is important to pay your attention to the left column. You need to go to drive control, there will be visible discs, currently connected to the system. Often, the system does not see an external hard disk, due to the wrong appointment of its letter. To change the letter, you need to click on the external media icon and change the drive letter. Then the letter is assigned, which is not yet in the system.

If not detected new Disc And it is first connected to the PC, it is probably not formatted, therefore it is not visible in the list of working devices. In this case, click on the media by creating a simple volume. In this case, all information will be deleted on the disk.

If the PC has stopped seeing an external hard disk, most likely, this situation is associated with the lack of drivers or system failure. Modern systems Pretty "smart", and when the new device appears, quickly search for the corresponding driver. But sometimes, as a result of the accumulated errors in the system, it does not detect the device.

First of all, it is necessary to explore USB port. To do this, you can connect a flash drive, a camera or smartphone. If the system saw the device, then the port works.

It is also useful to explore the components of the dispatcher of the device, it can be found in "Control Panels". The carrier icon is in "Other devices" or "Disk devices".

PC drivers can obstruct. By pressing the hard disk on the hard disk (in front of it an exclamation mark), you should select "Update Drivers". Finding drivers is provided special programs either search on the Internet.

Often, Windows is obsolete, it is the answer to why the computer does not see an external hard drive. You should reinstall the system.

Windows 10 does not see an external hard drive

Last generation operational systems may also not define an old or new medium. The carrier may not be formatted, not to have sections, as a result of which are not specified in the conductor.

When Windows's external hard drive stopped to see, you can go to the "Toolbar", then to the "Security System" and in the Administration subsection. Next, you should work with the section "Creating and Managing Hard Discs".

If you enter the "diskmgmt.msc" command, the utility that is called "Disk management". In this case, you can see the media, and its sections will have a blue shade. An unimpressed disk is highlighted in black.

You should click on the tab "Disc 1", Next to choose "Initialize disk". Then you must click on the black strip, and then to the "new section". In this location, a section is formed, where the free letter is assigned.

Large format discs are separated into several parts. You can format the carrier with the file nTFS system. When a person presses a button "Ready"The system will display the carrier.

If the PC does not see an external hard disk, provided that it is new, you can enter the BIOS, turn off the AHCI, then the computer is overloaded and the disk will appear.

Sometimes it is necessary to integrate the SATA driver to Windows 10 operating system. Only the newest drivers should be installed. Optimally, if this work will be charged with a competent person.

External carrier does not show PC if it has previously been subjected to mechanical effects. If the drive is used for a long time, then you can use special utilities To identify errors and badblets.

Virus media infection becomes the reason why an external hard disk is not visible. Windovz will block it. Also, the situation often arises, due to failures in motherboard, its diagnosis is shown.

To work optimally, it must be within dMA modes. When the disk functions in PIO, you can open "Device Manager"and then "IDE ATA / ATAPI controllers". Next, you should detect a heading « Extra options» and delete secondary or primary IDE channels. At the final stage, a system reboot is shown. In addition, the problem is solved by purchasing an additional loop.

If the drive overheated, the system can turn it off. If necessary, the cooler is installed and the device is cleared of contamination.

The power supply that was with the drive may be insufficient power. This will cause the system that the system does not see an external hard disk. It is better to use the original cable, it has the desired length and metallized latches.

External HDD is a popular option for storing information. The volumes of built-in disks in modern PCs are huge and users without thinking, all pictures, movies, music are preserved on them. But the time and volume of the built-in HDD becomes not enough. What to do if you delete data is not desire? The answer is simple - to purchase a portable hard drive and throw everything you need. Fortunately, the price of them fell and a remote hard disk per 1 terabyte may each.

But when connected, the device may not be determined correctly and it will not work with it

Consider the main reasons why the external drive does not work:

1. nutrition problems;
2. the necessary drivers are not installed;
3. faulty USB ports or cords;
4. viruses;
5. physical damage.

Restore the hard disk after the fall is difficult, for this you will need to appeal to service center.

Similar situation and other physical damage. Only with software damage to restore the external hard disk will help specialized utilities.

If the new external HDD is not visible

Buying an external hard drive, users hope that it will immediately start working and will not require additional configuration

Often it happens. Windows latest The editors are a rather smart system and automatically try to install the driver for the hard disk and activate it.

If this did not happen or the computer stopped seeing the hard disk first, it is worth thinking about nutrition. The characteristic features that food on the USB port is not enough:

• noise, cracking, vibration;
• periodic loss HDD;
• errors on indicators.

Try connecting the screw to another port and use the cable included in the kit, and not another manufacturer. Sometimes the external hard is determined only when connected simultaneously to two USB connectors.

For new hard drives such behavior is uncharacteristic. The main reason that the screw is not determined - in the absence of marking. It is executed by the user. Consider how the disc mark is performed:

• The first thing you need to do is to log in to drive.

fig.1. To do this, go to the PC settings and open the control panel

fig.2. We find the administration section in the system configuration and open the PC Management item

• Open the drives from the left column. The OS screen will display a list of all storage devices, including external.

Council. Often, the OS does not see the drive due to the incorrect drive of the disk, which can be changed through the context menu in the control of hard drives.

fig.3. For a new HDD change the letter of the disk will not work

• Select from the context menu item "Create a simple volume". The data will be erased.

fig.4. After creating a new volume, it is required to format the external hard drive

• Select the appropriate item from the context menu and set the NTFS file system in the window that opens.

Another option due to which the new HDD may not be determined - the problem with the device drivers. It is possible to eliminate it as follows:

• Check the USB port, turning onto the phone, USB flash drive or other drive.

fig.1. From the control panel, go to the Device Manager and see the device marked with yellow exclamation familiar

fig.2. From the "Actions" section update the configuration

An alternative to solving the problem is the driver-packs, but it is recommended to work with them only with experience in troubleshooting. In some cases, it will have to reinstall OS.

Council. Avoid Windows assemblies. It is them - the main cause of equipment definitions.

If the old external hard drive is not visible

Problems with already working on the computer also occasionally happen. They are often not caused by hardware problems and reanimate the hard drive is real without contacting the service centers.

Consider the actions that the usual user can take:

1. Change the letter of the disk. To do this, follow the instructions for the new HDD.
2. Check the drive for viruses. Malicious turns off access to the Winchestera and sets the lock for individual files. Maintaining topical anti-virus databases will help to avoid this problem.
3. Make sure that all devices in OS are functioning correctly. To do this, open the management of devices and make sure that there are no yellow or red warning signs. If necessary, update the driver from the manufacturer's website and inside the OS.
4. Reinstall Windows. It can help if the HDD works correctly on another computer.
5. Check the cords and try to change the port. Some USB ports may have a reduced supply voltage. After changing the port, the work of the drive comes back to normal. This problem is relevant for Acer laptops and others.

If yesterday, a well-worked hard disk without visible reasons At one not very wonderful moment stops working, it is like a catastrophe. Remembering the information stored on it, suddenly you start to understand that there is nothing valuable there - all the data is priceless. That's right, someone noticed that if the computer does not see an external hard disk, it is like the end of the world. Although everything is not always so afraid.

The main thing is not to succumb to provocations, and carefully think why what exactly has changed since the last launch? The correct answers to these questions allow almost half of the cases to restore the carrier's health independently. Next, we will talk about the main reasons, due to which the computer

Perhaps in his life every person had to at least once to fall when the most complicated mechanism I stopped working because of the failed detail. This fate did not bypassed hard drives, both external and internal. Currently popular USB hard drives, but exist with sATA interface, significantly superior to the first speed. Any external hard drive connects to a computer through the connector connector. Here is one of the most banal reasons why the computer does not see an external hard disk. There are two types of USB connectors: Some smokers on the motherboard and output with back side system BlockAnd others are mounted into the body with an outline on the front panel. Obviously, most users are connected to the hard drive to the most accessible connectors, that is, on the front panel of the case. And since only a few computer is assembled in a reliable building, then you should not be surprised that Chinese manufacturers saved on the elements of the connector. For example, sliding contacts may not be sufficiently spring-loaded, their area is reduced in order to save, and the materials used are too weathered. From this it follows that sometimes, by connecting the hard drive wire wire to the port, the external hard disk sees. The problem is in the connector contacts. You can solve in two ways:

• connect to ports on the motherboard;
• buy a high-quality USB extension cord - it is cheaper than casing replacement.

Next reason is the lack of nutrition. The USB 2 standard assumes the maximum current of 500 mA per port. So if too much is connected USB devices, then the Winchester may not have enough power to work. Solution: Remove all "unnecessary" (webcams, USB modems, etc.) or we buy a hub with a power supply. In addition, the front panel connectors are connected to motherboard Slender-wire harness, which also has its own loss of tension. It is worth remembering that these connectors are suitable, first of all, for low-power devices (flash drives, phones).

If a hard disk does not work, then you need to check the BIOS settings: whether the USB ports are not prohibited. For devices using "pocket" (mobilrack), it is useful to check the condition of the internal loops and connectors - perhaps the reason for them.

After that, you should believe software Computer. Although external hard drives are designed to work "from the box", usually without requiring any special drivers, however, in the system you need to install the software package for the chipset. This is especially important for generations to Windows Vista.. A configuration configuration configuration can also be observed, in such a situation, a computer cannot completely boot at all.

Of course, the inner breakdown of the Winchesis itself is possible. It is not always possible to restore it to restore it, so you need to know where the nearest service center is located.

External hard drives (Portable HDD) are becoming more and more popular with each day. It is also clear, a huge amount of memory and relatively small sizes are the main advantages of such devices. Yes, and in the connection to the computer, they do not differ from the usual flash drive.

But not always everything is so good and wonderful. Often, users of removable USB drives are faced with one very important problem: Hard disk is not defined!That is, the user connects the device to the computer, but nothing happens, the computer simply does not see it. And there may be several reasons for this, consider the most common.

First we define what is the problem?

In a hard disk or in the computer itself. Well, of course, first, try to connect the disk through another USB port. It happens, helps. 😉
If there is such an opportunity, try connecting your portable HDD to another computer. If the disk is determined, then it is obvious that the problem is in your computer.

Let's start with the simplest:
1) Check driver Removable disk. To do this, go to Device Manager. If you have installed operating windows system 8, then it can be easily found through the search. Or
Start → Control Panel → Equipment and sound → Device Manager.
In the Manager, select Disk Devices and find your disc. Press the right mouse button and choose "Update Driver". You can try to delete the driver, restart the computer and install again.

2) Next reason - incorrectly assigned a letter external disk. When I ran into such a problem, the letter did not assign the letter at all, I had to specify manually. It is solved quite simple. We go on the next way:
Start →Control Panel → system and safety → Administration → Computer Management.
Choose Disk management and find your disc. Click on it right mouse and click "Change the letter of the disk or the path to the disk ..." Choose any free letter.

3) In the case when the computer refuses to determine and flash drives and hard drives need to check uSB support in Bios.maybe she was disabled. Fortunately, this happens infrequently. Yes, and not every user himself will venture to customize something in BIOS. But this will be a separate article.

4) Another option is a problem with power unit Computer. Either too much equipment is connected to the computer, or if the computer is not new, the power supply is simply outdated - in both cases it does not cope with the disk.

Well, what if the disk is not determined on another computer?

Perhaps the problem again in nutrition. If you connected the disk through the extension, then try it directly using a USB cable that was included when purchasing.

In the event that the disk has a second connector or its own power supply - connect them.

But it happens that the problem is mechanical damage Portable HDD. This option can be assumed if when power is applied to the disk, it does not publish characteristic sounds. The device simply does not work. Of course, in this case, you must contact the service center and in no case try to disassemble and repair yourself. It may not end. 😉

I hope that this article will help you solve the problem of an indefinite disk. Good luck! 🙂

Often, users face a problem when an external hard disk does not open what to do in such a situation?

To return to life a non-working device, you need to perform a number of very simple actions.

Restoring a new disk

If you do not see the new HDD in the My Computer folder, you just need.

This function will allow correctly configured sections. hard disk and marking data storage area. Follow the instructions:

1. Open the control panel menu;

2. Then in the Administration tab, click on "Computer Management";

Fig. 1 - Computer Management System Window

3. On the left, click on the disk management menu and wait until the data window appears on the right side. It may take a few minutes;

Fig. 2 - Drive Management Menu

4. In the window that opens, you will see absolutely all drives that are available on the computer;

5. In contextual hDD menu Click on "Squeeze Tom". The compression process allows you to select an additional unintended area;

Fig. 3 - Tom compression process

6. Wait a few minutes before the system automatically define the most accessible space that can be compressed. In a new window, check the parameters and click on the acknowledgment key.

Fig. 4 - compression space

Note! Often the HDD is not displayed in the explorer due to the wrong name of its letter. In the disk management window, you can change this option (right-clicks to the HDD name and select "Change Letter or Path"). Remember that in the operating system there can be 2 disks with the same symbolic designation. Then you need to restart the computer and everything will work fine.

Driver update

Due to lack necessary drivers and settings may not be displayed in the disk management menu. What to do in this case?

To correct the problem, it suffices to install drivers using the standard Windows Device Manager.

We advise connect hard storage To any other computer and test his work. If everything is functioning normally, there is a 100% chance that there are simply no necessary drivers on the first computer.

Perform the following steps:

1. Right-click the manipulator on the Start button. In the appearance context menu Find the Device Manager and open it;

Fig. 5 - opening dispatcher

2. In a new window, wait for all components connected to the PC. Right click on upper string - The name of your computer. . To automatically download and install the drivers, you will need to connect to the Internet. Configuration update can take some time;

Fig. 6 - Equipment Update

3. If errors occurred during the driver installation, go to the "Other" sections and "Disc devices". In case of errors, the element of the hierarchy will be marked with an exclamation mark. By clicking on the appropriate item in the context menu.

In this way? You can easily establish the work of HDD. After upgrading, restart the operating system to make changes to force.

How to speed up the work of the computer: Optimization Tips

HDD is not displayed after formatting

The situation often occurs when, after deleting data and format partitions, the disc stops connecting to the PC.

The user connects the device, but there is no "My Computer" menu. At the same time, the computer defines a disk in the section "Devices and Printers".

Perhaps in the process of formatting sections was damaged file system disk. It can be restored using the command line.

Open this system utility by combining the Win + R keys and enter the CMD command in the text box. Click on the "OK" button.

Fig. 8 - Opening the command line

In the window that appears, enter the command chkdsk. and disk letter. Press Enter. The system will automatically determine all the errors that occurred on the drive and eliminate them by changing the file system.

The result of the execution of the command is indicated in the figure below:

Fig. 9 - Command CHKDSK

Unable to run the disk

Eli drive absolutely does not respond to connecting to a PC, it can be disassembled and checking the device for the presence of printed circuit board defects.

Its elements can be burned due to a sharp voltage drop. As a rule, the elements of the combustion board are protected by special TVS type diodes (they are marked in the figure below).

One of the diodes can be broken due to the same voltage drop. Check the two TVS components using a voltmeter.

With a zero resistance detected, you can talk about the burden of the diode. Replace the item to the new one.

Strange sounds during HDD

If you heard strange noises (crackling, click, hissing) while the drive is running, you turn off it as quickly as possible.

The device should be showed by a specialist, because most likely damaged magnetic disk or its head. Turn on the disk again before repairing is not worth the repair.

This can lead to its final breakdown. The specialist should replace the broken head and clear the device from pollution, as well as restore all the data.

The problem with the power of the external drive

If you use a powerful external drive, it is likely that it lacks the power, so the PC does not define the device.

Due to malfunction, the disk can also spontaneously disconnect.

The external device works through a connection with a computer via a USB connector. As power electric current In such ports is limited, the disc may not be enough charge.

Several tips:

• Use a short USB cord. The most common cause of bad work is to use too long wires. Most of the charge received from the port simply does not reach the drive, as it is lost on the way. We advise you to use only short wires that are supplied. official manufacturer Your HDD;
• The external drive has two connection connectors? In this case, it will be more expedient to use them at the same time, since one port has enough for data transfer, but for obtaining required charge We need a second port;
• Perhaps the power supply of your computer is simply incompatible with the acquired external Drive. In this case, the only output is replacing the outdated power supply.
