Computer sees USB flash drive as drive

The flash drive sees as a removable drive. Sees the flash drive as a removable drive

In section Hardware on the question USB-storage. Computer sees removable drive L, but can’t do anything with it. there’s a way to revive it? Given by the author Nosogreyka the best answer is it will work if you do it right and sensibly. I’ve already lifted a dozen flash drives, and of different kinds, according to this technique:Software malfunction controller.In any flash drive installed microchip-controller. It is responsible for transferring data between computer and flash memory. The controller is controlled by the firmware. In the case of various power failures, improper removal and other causes. the controller’s firmware fails. As a result of which the controller is blocked and does not respond to requests from the operating system.When connected to a computer, the flash drive may be recognized as an “unknown device”. Have a RAW drive or can be read as a zero-capacity drive. You may get an “Insert Disk” or “No access to disk” message while trying to access it.Sometimes, the flash drive becomes read-only. Data is visible and readable, but “The drive is write-protected” message is displayed when trying to create a file, erase or format it. In this case the controller enters the data protection mode when it detects errors in the firmware or flash memory to prevent its further destruction (NAND memory installed in the flash drive is damaged mostly when writing data).How to recover a flash drive.1. Find out the model of the chip-controller to find a utility for working with it. There are two ways to do it. First. open the flash to see the controller model name printed on the chip. If it is problematic to open the case. we use the second method. It identifies the model by VID and PID codes in the controller firmware. VID is the manufacturer identifier and PID is the device identifier. VID and PID are present in any USB device. These codes can be read by programs like CheckUDisk 5.0, UsbIDCheck, ChipGenius v2.64, as well as by means of the operating system.I used CheckUDisk 5.0If you can not read VIDPID or it is empty, then there is a good chance that your chip is electrically damaged. In this case we can’t fix the drive using software means.2. So, we were able to read VIDPID, so chances to recover it are. Then according to VIDPID you can find the manufacturer of flash drive and model of controller installed (for example with the help of iFlash database). After identifying the controller, let’s search for a service utility to work with it. CHECK IT CAREFULLY! There are some that can kill your flash drive permanently. 3. You can find a suitable utility on the manufacturer’s web site or in the utility catalog on the web site at. For your convenience the utilities are sorted by controller manufacturers. there is no 100% guarantee that the downloaded tool will help you, it is possible that another one will help (not related to your flash drive in any way)!) For example:You have found out that VID of your flash drive is 1005 and its PID is B113. According to the database iFlash find that the flash controller PS2136 firm PHISON. Utility for this USB 2K REL90 (PS2231-UP12) controller. If you opened the enclosure and determined the controller type, you would go straight to the file directory and search for the appropriate utility.I will not describe how to work with the utilities, as there are many utilities, and the order of some of them is described in the instructions, which can be found in the archives with the utilities or read in the Комментарии и мнения владельцев to them.After you restore controller’s work there is a great chance to pull some data from flash drive’s memory. You can use PhotoRec to do this.If the data is no longer needed or the information is completely destroyed, it is recommended to test the flash memory for bad sectors. You can do this with MyDiskTest v2.42, Victoria 4.3 Beta or Flashnul 0.99. not used part of the article from _www.flashboot.Open the device manager in the Start menu and go to the device manager (kudos to them for that)

Why can’t the computer see the USB memory stick or hard disk drive?

Usually software malfunctions, incorrect operating system settings, outdated drivers, malfunctioning USB ports of the computer, adapters or the drives themselves are suspects in this case.

Buy a computer with the competent installation of all the necessary drivers that would work correctly you can on our website.

Depending on the causes, in each case the problem manifests itself differently. Sometimes the computer doesn’t respond at all to a USB flash drive or a hard disk drive. In other situations, you will hear a new device sound, but the drive icon still does not appear in Explorer. And sometimes the computer just hangs right after making contact with a USB device.

What to do if your Windows computer can not see your USB stick or external drive

First, determine what the problem is with your computer, the adapter (if it is connected by cable), or the drive. Try connecting the USB device through other ports. If it does not and you are using a cable, try replacing it with a spare. If not, check to see if the drive opens on the other computers.

If you see the drive without a volume label in the “Disk Management” menu, it may be causing a problem. Then right-click on the disk and assign a letter to it using the appropriate option in the context menu.

Then reboot your computer. the drive you need may finally appear in Explorer.

Check your hardware settings in “Device Manager. To open it, type devmgmt at the command line.msc and press Enter. If you see a device in the manager that is not working (with a question mark or exclamation mark), an update may help.

Right-click on this device and click “Remove”. In the top menu, click on “Action”. → “Update Hardware Configuration”.

Install the latest updates for Windows. Without them. especially for Windows XP. the operating system may not have the necessary corrections for working with modern USB drives. It is also a good idea to update the drivers.

If another PC does not see the flash drive, or all the above tips did not help

If so, the problem is most likely with the drive itself.

If you have a flash drive, but not a hard drive, you can use special utilities for fixing programming errors. This software is usually available from the manufacturer’s website. For example, the program JetFlash Online Recovery for Transcend flash drives. And USB Flash Drive Online Recovery is for flash drives of ADATA brand. But be aware that in the recovery process these utilities erase all data from flash drives.

What to do if your Mac can’t see your flash drive or external hard drive

On Apple computers the verification procedure is a bit different, but it follows a similar algorithm. Let’s assume that you have already tried rebooting your computer, disconnecting and reconnecting the flash drive, and verified that the connection is secure. If this does not help, you should do the following:

Check the drive in “Disk Utility”. Open the built-in Disk Utility (Programs → Utilities → Disk Utility) and see if the problem stick is detected there. If the drive is still visible, try reformatting it by pressing the “Erase” button and reconnect it. Keep in mind that all data from the flash drive will be irretrievably erased.

Check the drive in “System Information”. A special Mac diagnostic program provides detailed information about all software and hardware components of your computer, including USB devices. Open the Apple menu, then hold down the Option key and click on “System Information” and go to the USB section in the menu that opens.

If the stick is there, it means that the problem lies in the software and the drive can be tried to restore, referring to the manufacturer’s recommendations. If there is no information about the flash drive, then the matter is a physical malfunction, and you should contact the store or a service center, if repair makes sense.

The flash drive is not detected due to a malfunction

It is not always possible to fix the problem which causes the computer to stop recognizing the USB flash drive. To determine the USB malfunction, you can use the Device Manager:

  • Go to the “Start” menu and type “Device Manager” in the search box.
  • In the menu that appears, select the “Disk drives” category.
  • A subcategory will open and connected drives will appear.
  • If the flash drive does not show up in the list, you need to insert it into another computer device or laptop. The situation has not changed? So the USB device has a burned controller and can not be recovered.
