    1TB USB drive will not retain data


    I run an older computer, PC compatible, roughly from 9 or 10 years ago, running W10 (Pro, i think) with all updates. Lately i have consecutively gotten several (three of them) 1TB USB "thumb" drives. In every case they will store up to about 100 - 175 MB of data, but when i exceed that i suddenly find directories with no files in them at all, exactly like all the files within the directories were deleted, but the directories were left intact.

    I did try to format the first one, first a quick format, and after that failed a full format that took two to three days to complete. Still had the same issue.

    I first blamed the drives, as this experience has been one drive at a time over the last month or so, but now, three drives in a row, i suspect my hardware. The vendor refunded my money and i got yet another drive from them, but now i feel like i am the problem, not them.

    How do i diagnose if it is me or not? I do not have access to any more recent computer off-hand, which would have been my first step. To note, i do believe these are all USB 2 as is my computer, but i have made mistakes in my assumptions before. I apologize for my lack of knowledge-

    This is the drive - Amazon.com

    Many thanks for your kind support and knowledge!!!

    I suspect it is a fake - it nay have some capacity, but unlikely 1TB at that price. Have you read the reviews? - not just the 5-start ones - although one of them rated the device 5 stars merely to ensure his warning gets read! The behaviour of appearing to work OK until a 'large' amount of data has been stored is typical. It means most users won't notice, at least not immediately.

    See this for details: Be aware of fake 2TB USB sticks on Amazon that can cause data loss - Myce.com

    That is 4 years old, but they didn't stop: this from earlier this year: That cheap 2TB USB stick is probably fake - here’s how you know | The Star

    5 Tools to Test and Detect Fake or Counterfeit USB Flash Drives Raymond.CC I have used h2testw for years to test actual capacity vs fakes, even if it came from Amazon - and I test them before using them.

    Just read reviews, i feel like an idiot. I almost always will check them first, but i guess i just didn't think.

    Thank you both for your responses and education!

    MERRY CHRISTMAS, HAPPY NEW YEAR, and pray all this Covid stuff goes away, both actual and political!

    Don't feel that way ....... we don't know what we don't know, then we learn. If we can help further, let us know.

    Thanks for your good wishes and wishing the same for you too.
