Recording and reading issue for JPG files

Solved

Hello,

I transferred folders containing JPG files onto a USB key. Each file bears the names of the people appearing in the photos, so there are many characters.

The transfer seems to go through normally, but when opening some folders either

- the files do not open due to incompatibility

- the photos appear “incomplete” (gray band)

- the files have disappeared

Could the fact that the filenames are long be the cause of these problems?

Thank you for your advice.

    Hello,

    This is the fake USB key syndrome.

    Do you want to go further in solving the problem, see reprogramming the Flash disk? with firmware if possible, if the capacity was fake from the start?

    The USB keys should be reprogrammed, (Not you and me) or sent to Recycling

    Tell me more about the key, (Brand, Model, Capacity) * If applicable

    And post a report (created with the key connected) with ChipGenius, as explained at the bottom.

    Note: It is a tool to extract information about USB hardware, (Controller chip model, memory chip etc.) It can be perceived as malware by antivirus software even though it isn’t, I’ve been using it for years, nothing to fear.

    Disable SmartScreen and real-time protection of the antivirus while downloading, extracting everything, and running ChipGenius, or add the files to exceptions.

    Otherwise it’s the same thing, behind the version at the bottom here with a password:

    https://www.usbdev.ru/files/chipgenius/

    Run ChipGenius, and right-click in the ChipGenius window then close the small information window (Which means the report is copied to the clipboard) with "Ok", then use Ctrl + V to paste the clipboard text into your next reply.

    They are keys bought in a bulk on CDiscount for 20 bucks.

    The error message is "It seems we do not support this file format."

    I just did other tests by transferring jpg, OpenDocument and PDF files not originating from the initial files, and there was no problem.

    All the problematic files are photos and documents scanned from originals.

    I don’t understand anything...

    So I deduce that you don’t want to try the first method I described?

    I’ll give you a second one that’s different.

    Format one of your USB drives and then test it with H2testw

    https://www.commentcamarche.net/telecharger/utilitaires/11535-h2testw/

    You’ll be able to post the report, which will probably be unambiguous; I think your USB drives are

    Hello,

    I tested the keys with H2testw, and your verdict is unfortunately correct... The keys are faulty, I requested a refund from CDiscount.

    Thank you for your advice.

    But no explanations about why some files don’t pose a problem... The mysteries of computing...

    It depends on the actual size, and on the good blocks vs the bad ones (Falcified), whose firmware makes Windows believe they exist when they don’t, Windows only sees smoke and mirrors...

    If you have a batch, I can help you reprogram them in bulk to their true size, if we can find the tool for it; a pure ChipGenius report is needed to know the controller of the keys, without that, we’re shooting in the dark, it would be like looking for a needle in a haystack.

    Then it depends, it can be simple, as complex, as impossible; nothing ventured, nothing gained.

    I couldn’t give a verdict on that without you trying.

    You had an idea of the real size of the keys with H2testw; we might be able to give them that size, and have them reliable afterward, no more loss of jpg or other files, but size reduced to reality.
