    When attempting to format USB Drive, it disconnects.


    Hello,


    I am trying to format a SanDisk Cruzer Glide 16GB USB Thumb drive.

    When trying to format, after a period of time I get an error message that its no longer assessable because it has disconnected on its own.


    Ill give out any info when question is asked.


    Thank you.

    :)

    How To Format A Write Protected Flash Memory ?

    ¿You already tried this one?...

    Run CMD


    1. diskpart
    2. list disk

    Then in the 3º step, put the correct number of disk in the list for the usb flash (if it's listed in disk 3, then you'll have to write select disk 3).

    2. select disk #
    3. clean
    4. create partition primary
    5. select partition 1
    6. active
    7. format fs=fat32
    8. assign
    9. exit

    with that commands you will format the flash drive in fat32, if you have a large drive you can select also "format fs=ntfs" in step 7.

    good luck!

    USB Flash Drive saying not formatted..?

    Hi,

    I have a Memorex Poker Chip USB Flash Drive 1GB, and It shows up fine on one PC as "Poker Chip" in explore, and I can transfer files... but on my other PC (the one I'm on now..specs in profile) it's listed only as H: Removable Disk, and when I click on it, it says: "The Device is not formatted, would you like to format it now? (Y/N). Why would it be recognized on one PC, but the not the other? How come the other PC didn't need it formatted? When I click yes to format it, it says: "Windows was unable to complete the format"

    I went to the BIOS and USB 2.0 is enabled. And Device Manager does list it as a Memorex Poker Chip..

    When attempting to format USB Drive, it disconnects.

    help. USB drive isn't assigned a drive letter.

    Any usb flash drive I plug into my computer isn't assigned a drive letter. The physical drive shows in the "safely remove hardware" but it doesnt show up in disk management. I have tried to populate the volume thru the safely remove hardware properties window and it does pop up in the list but it doesn't stay there. This isn't a format or assign a letter problem. It's more complicated then that. Maybe one of the services needed for usb drive management was disabled? Suggestions needed. btw external usb harddrives work fine.
