    Does Windows 10 support disk on key 1TR?


    Hi,
    I just bought a disk on key (DOK) 1TR. The device file system is exFAT.
    When I try to copy files (movies for example) it copies as looks like OK.
    Some of the files work (from the DOK), some not although they all work on my PC.
    When I try to copy some more files - some of the already copied files disappear.

    I must add that another DOK 1TR behaved the same. I formated it to NTFS, took 4 full days to complete.
    Now, the PC does not recognize the previous DOK.....

    Any idea for the present problem?
    Thanks a lot

    It is a Flash Drive. Normally USB thumb drives are formatted Fat32.

    thank you.
    If I try (as I did in the previous DOK) to format I get no option as Fat32. The alternative is NTFS.
    Besides, Files larger than 4GB can NOT be stored on a FAT32 volume.

    Fat32 is common use. Unless you are trying to store large sized media files on it, Fat will work just fine.

    I am trying to store large files , of course.
    When you say "Fat will work just fine" you mean Fat32, right?
    I am at a stage where I would like the DOK to work one way or another.
    How can I format to Fat32 when I don't have the option in WIN10 format manu ?
    Thanks a lot.

    If you are planning to do large files then forget formatting to FAT32.
    And if by DOK 1TR you mean a 1TB USB Flash Drive, then put the drive into the computer, if using a Desktop, place it into the Back USB port not the front or though a Hub as these ports are weaker.
    Go to Start/Search and type diskmgmt.msc, Right click the diskmgmt results and Run As Administrator. In the Elevated Disk Management window in the lower pane, if you see your Flash Drive there, right click the File system and choose to Format. You should be able to choose NTFS, or exFAT.
    If the file system says Unallocated Space, then Right click it and choose to make a simple volume and then format it. You can just do a quick format. If it takes a really long time, or it doesn't complete there is a problem with the Flash drive and it needs to be replaced.

    Thanks Spunk for the detailed answer.
    I do mean 1TB USB Flash Drive.
    In the first place , the Flash Drive was formated as exFAT and yet, as I tried to copy some more files - some of the already copied files disappeared.

    This is the second Flash Drive I am trying to work with, both 1TR.
    I will try the method you suggested and let you know. Hope it will work.
    Tnx again,
    Moshe

    Are you sure the flashdrive is legitimate?

    There are very few legitimate branded flash drives of that capacity (e.g. Kingston); typically they sell for hundreds of dollars. If you're using DiskOnKey as a brand name, I am unable to verify a legitimate 1TB flash drive sold under than brand.

    There are a lot of counterfeit 1TB and 2TB flash drives out there, whose actual capacity is a small fraction of what is labelled. It might be well to verify it first.

    Sorry to say the none of the solutions worked for me.
    As far as I read on the net, Windows 10 does not support a flash drive this size 1TR.
    Microsoft suggests "
    you can try EaseUS
    partition tool
    to do the USB formatting job". Nothing less and of course it cost a lot of money
    and there is no guarantee it will work after all.
    BTW, Windows 10 says "... it is impossible for you to format flash drive which is larger than 32GB from NTFS to FAT32 by this way"

    So , the problem is still on...
    In case anybody can let another solution or any Freeware I can use of test befor buying I'll be more then glad.

    Thanks guys.

    Did you verify the capacity, as I suggested in post #8 above, using ChipGenius, h2testw, or the Quick Size Test function of rmprepusb? (the last of which, by the way, can partition and format it for you. You have to enable the "view large drives" option to make a flash drive of that size visible in the menus). These programs are all free. Please run them and post screen shots of the results.

    Your description of disappearing files on two drives of the same type, strongly suggests that the flash drives are defective in design or misrepresented. Can you post a web link to the product page describing this 1TB-sized flash drive by brand and model number?
