Incorrect flash drive formatting (file system is not compatible with Windows)

The Windows operating system refuses to see files on a flash drive if the file system format of the flash drive is not compatible with it. This could happen because you formatted the drive in another OS (for example, Linux or Mac OS X). If your computer or laptop does not see the memory card, the problem may also be due to incorrect formatting.

How to fix the problem. We recommend formatting the usb flash drive in FAT format. as the most universal. This can be done both by means of operating systems, and using special programs: JetFlash Recovery Tool, USB Disk Storage Format Tool, etc.

Damage to the file structure of a flash drive by a virus

One of the types of relatively harmless viruses (Trojan-Downloader.Win32.VB.hkq) makes all files hidden (without deleting them), replacing them with executable files of the same name. As a result, the Windows operating system does not see the files on the USB flash drive, and you cannot see the contents of the USB flash drive without removing the protection and neutralizing the media from viruses. If the computer does not see the phone’s memory card. it can also be a consequence of a viral attack.

What to do. Any antivirus program should fix the problem, fix the errors. One such utility is Dr. Kureyt.

1. Download and install the Dr Web Cureit healing utility on your computer.

2. Press the button "Select objects to scan" to select a storage device

3. Run a file scan on a USB flash drive

Video instruction:

In this article, you will learn how to remove protection from a USB flash drive, remove viruses, make all the necessary files visible, and fix errors on the storage device.

Small and easily fixable flash drive hardware malfunction

It is likely that the computer does not see the flash drive due to the fact that the device has malfunctions. Due to the presence of bad sectors, the usb flash drive stops working, Windows is not correctly recognized, or it reads files with problems. Also, due to the presence of bad blocks, information from the device is read slowly, with errors.

What to do? We recommend installing the Flash Memory Toolkit on your computer. It allows you to check errors on a flash drive, to conduct a series of small and quick tests of the speed of reading and writing information. The test results will open a complete picture for you and you can determine why your computer does not see the USB flash drive and fix the problem under Windows.

The flash drive stopped working due to a relatively complex damage to the usb drive

No one is safe from serious damage to the USB flash drive, including physical damage to internal components, chip chip, short circuit of the USB flash drive circuit board or deformation due to temperature increase or improper operation of the device.

The easiest way to determine the breakdown of a flash drive by eye: deformation of the body, thermal effects, other mechanical damage. If the usb flash drive falls to the floor, the connector connecting the board with the usb connector on the computer could break off.

What to do? You can read about how to repair a Kingston flash drive and other models in the article here. However, it must be honestly acknowledged: most likely, repair is impossible, or repairing the drive will cost a lot of money. In addition, not every specialist in your city will undertake chip soldering without a donor.

The USB port of the computer or laptop does not work; port defective, damaged or not connected to the motherboard

It’s a rather banal reason, and nevertheless, this also happens. The problem is solved very simply. remove the USB flash drive from the usb-socket and try other free ports for reading the USB flash drive. If successful, you will hear the characteristic “victorious” sound of Windows, or at least the icon in the notification area that the USB flash drive is connected to the PC.

Consider the case when all your USB ports are not connected to a PC. In principle, this is impossible, because the motherboard de facto has sockets available for connecting devices. here the only question is in supporting specifications, the relevance of the mat. boards. However, many users are accustomed to connecting a flash device through the front panel of the computer. And on this front panel you need to output wires from the motherboard.

How to solve a problem. In this case, a specialist call will help. If you. an experienced and bold computer programmer, you will figure it out yourself, because of which the usb port does not work.

Here we need to make a remark: a similar case of not working usb is relatively rare, and it makes no sense to start proceedings, why the computer does not see the USB flash drive by unscrewing the screws on the system unit.

Missing flash drivers or outdated “firewood” for Windows installed

The conflict between the drivers of a usb flash drive and the OS is rare: modern operating systems in most cases determine the drive model and install drivers without problems. In other words, the computer is unlikely to see the flash drive due to missing drivers. However, such an error does occur. You may encounter the fact that Windows XP is installed in the print center, and your flash drive is simply not detected on the “old” Windows. In fact, the laptop does not see the flash drive due to the outdated operating system installed in the service center.

What to do. Make sure your usb-flash drive is compatible with the current operating system. As a rule, information about supported OSs is on the box or on the device manufacturer’s website.

The comp does not see the flash drive due to incorrect BIOS settings

In rare cases, the laptop does not see the USB flash drive due to the erroneously set parameters of the usb controller in the BIOS. This is possible when assembling a new PC or changing the motherboard, if you changed the BIOS settings (or someone made a configuration without your knowledge).

What to do. Enter the BIOS, holding Del or F2 while booting. If after pressing these keys the BIOS does not open, check what the PC writes at boot: you may have another button assigned.

Find the Advanced Settings section in the BIOS.> USB configuration. The USB Controller parameter must be activated by setting it to Enabled. Save the settings by pressing F10 or through the BIOS menu, restart the computer and check if the computer sees the USB flash drive.

The card reader does not see the memory card

When connecting an external card reader to a usb port, the computer does not see the card reader. As an option, the computer does not see the SD card when reading from a card reader.

What to do? If your card reader does not see the sd card, the reasons can be quite commonplace. Let’s say this could well be due to a broken card reader. If possible, use another card reader, for example, a built-in laptop. It also makes sense to replace the cable connecting the usb port with the card reader.

USB port of a flash drive clogged with garbage

It is very important to store the USB flash drive with the cap closed. Some owners of flash drives forget about the correct operation of the usb drive, which is why problems arise. With careless storage and constant use, debris accumulates in the connector of the flash drive, which complicates the contact between the flash drive and the computer.

What to do. Thoroughly blow out the USB flash drive connector, making sure by eye that it does not contain husks, dust, or foreign objects that have fallen from your pocket into the connector. The most difficult case: the port is clogged with dirt and access to contacts is impossible without cleaning. Take a stick, a match and clean the connector and internal contacts of the flash drive.

After that in "Device manager" This flash drive appears with a problem "Code 10", "This device cannot be started". Why doesn’t the computer see the flash drive?

P.S: During the connection, a sound is made that the USB is connected and the notification diode on the USB flash drive also works.

Answer. Perhaps the file table has flown, so Windows does not see the USB flash drive. Try formatting the flash drive with proprietary software (if available on the manufacturer’s website). Alternatively, try a program for low-level formatting. HDD Low Level Format Tool.

If there is no physical damage on the flash drive and the antivirus was the cause, there should not be other options. over, formatting. the only method to programmatically affect this storage device.

When you connect a flash drive, the software is installed. Windows shows that the device is ready for use, but the computer still does not recognize the USB flash drive. Why?

Answer. Go to "Drive management" and check if the flash drive is defined as a file volume or unallocated space. Has the meaning:

I have a 32 GB Silicon Power flash drive, the computer does not see the flash drive. It appears in the disk manager as unallocated space, but an error appears when you try to create a simple volume. As a result, the computer does not see the files on the USB flash drive, the explorer writes "Insert disc". What to do?

I bought a new Xiaomi redmi note 4 64gb phone, I took the 10th grade SanDisk 64gb memory card from the old one, having previously formatted it with standard Windows tools in ExtFAT with a standard cluster size.
After formatting, the Explorer does not see the memory card; when you try to turn it on, it writes to the phone "Failed to safely remove the device: sd card sandisk", when you try to format in the phone, nothing just happens. How to win this?

Answer. The point here is not that the phone does not see the flash drive after formatting. The memory card model may not be supported by your mobile device. this happens often. In addition to exFAT, try formatting Fat32. Test the card on any other Android device: is the flash drive readable?

I try to recover deleted photos using the Recuva program, but when connected to a computer via USB, the computer does not see the memory card, the phone appears as a portable device. The USB debugging icon is turned on, while at the same time it turns on MTP enable. What is better to do in this situation?

Answer. When restoring files from internal memory, you need to make its image (see the instructions http://softdroid.net/vosstanovit-dannye-vnutrenney-pamyati-telefon-android), and only then mount a copy of the internal memory as a separate disk. Only after these complex manipulations Recuva will be able to detect the disk.

If the computer does not see the sd card, and not the internal memory, then this is another question. The fact is that you do not need to connect a memory card to a PC via a cable, but using a card reader. Only then will the sd card be displayed as a disk.

When I tried to format the flash drive, the computer issued a message: “the disk is write-protected”. It was not possible to format, but the flash drive completely stopped seeing the computer. The indication on the flash drive is on, but does not detect the flash drive itself. What can be done in this case? 32 gig transcend flash drive. Thank you in advance for any useful information.

Answer. You can check the performance of the flash drive through Disk Management (Start. Run. diskmgmt.msc). When you connect a USB drive, a new device will appear in the list. In order for the flash drive to be detected again, you need to create a new disk on it and format it. You can do this in the same Disk Management.
