Usb flash drive is not recognized

I have a couple of flash drives that don't show up when I plug them into my laptop or docking station. The computer can see that it is plugged in and you can remove it by using the system tray stop icon but it does not turn up in windows explorer.

Could someone step me though giving the flash drives a drive letter?

Re: Usb flash drive is not recognized

You need to go to the disk management utility located in the control panel under system tools or performance and maintenence depending on if you are in classic view or XP view.  If it shows up there, right click on it, and select "change drive Letter" click yes to the dialoguye warning box, select a different drive letter from the list and select OK if another warning comes up, say OK, I forget when it comes up.  9 out of 10 times, this fixes the problem

I am a student in school, and I am not to computer savvy on Flash drive.. It did not come with any instructions on how to use it. It is a Cruzer USB 2.0 Flash Drive (4GB) Can you help me with step-by-step...

  • Boot up your computer and find an open USB port. These are small, rectangular ports typically on the sides or backs of laptop computers, or on the fronts or backs of desktop towers.

  • Plug your flash drive into the USB port. The drive will slide in only if it is turned in the right direction, so if you have trouble inserting it, turn it over.

  • Make sure your computer sees the flash drive. It should launch a menu, letting you know that it has found a new storage device. You can choose an option from the menu or close the menu if you don't need to immediately access the flash drive.

  • Install the flash drive's driver if your computer doesn't recognize the flash drive. The flash drive's packaging should include the manufacturer's website address. Open your Internet browser, go to that address, and download the flash drive's driver from the site. Install the driver on your computer. After that, your computer should be able to recognize your drive.

    My laptop does not see my sandisk when I plugged

    Files on a flash drive can be corrupted if it is not removed from the USB port properly.
    Before removing the flash drive click on the Safely Remove Hardware icon and then click on the flash drive you want to remove and then remove the flash drive when the computer message says it is Safe to remove.
    To restore the flash drive you need to format the flash drive, but you will lose the data stored on the flash drive.
    If you need the data on the flash drive these WEB sites may help: -

    I plug in the sundisk cruzer 2.0 GB USB device and all it does is blink. It will not show up on my computer for the drive.


    If the computer recognize that there is a device plugged into the system, then just try to plug the flashdrive into another port at the back of your case.

    If the computer does not recognize that there is a device plugged in, there is a problem with your flash drive. It still gets power from the computer(Bliking light), but there is no data transfer between computer and flash drive.

    If it is still under warrenty, send the flash in for repairs(presuming that your USB ports work), otherwise try and see if it works on a other computer. If it does, the the problem is with the USB ports on your computer. I really hope this can be of help.

    Best regards

    Verbatim 1GB flash drive data recovery

    Sounds like you broke something ;)

    If your computer does not recognize anything when you plug it into the computer, your problem is most likely a broken contact inside the usb drive.

    You should attempt to open the drive, and see if one of the four contacts on the inside of hte usb key are no longer making their way to the circuit board, and try to reconnect it.

    IF you can push the connectors down with your fingers and make contact temporarily, and the computer recognizes it, try to just hold it there while you copy all your data off. Then throw away the flash drive.
