    Disappearing DAT file on new USB Drive


    I purchased a 1TB USB Drive and plugged it into the USB port on my laptop running Windows 10 22H2 . When I selected the associated drive letter the drive opened and there were two files present, the normal System Volume Information file and a DAT file, which I did not get the name of as it disappeared within seconds. Is this a normal windows operation to add a DAT file when a new device/USB drive is added?

    :)

    Urgent! All files on my USB drive's suddenly disappeared

    Hi. Thank you, I did as instructed and only two files are listed. I can actually see them myself after opting to show hidden files in File Explorer:

    The drive did contain hundreds, if not thousands of user files.

    Actually, on the first screenshot (second picture) it's open, that can be seen in the address bar (even though on the left 'my computer' is highlighted in blue, no idea why. Too bad MS forces local languages upon users, I would have opted for English but instead it chose Bulgarian for me... I still hope I can make the situation clear enough)
    Anyway, I took a new screenshot as suggested:

    I just looked up the drive's status in Disk management, it's listed as healthy, active, primary partition.

    Saving a .dat file to Sd

    I formatted the SD card in camera as instructed. I inserted it into the computer and copied the .dat file to it. It's not seen by the camera nor is it there when I put it back into the computer. I checked by doing it all again. Saved to Sd. Took the SD out of the computer. Put the SD back into the computer and the .dat file is gone. Insanity looms. The .dat file disappears from the SD.

    Disappearing DAT file on new USB Drive

    need some help opening a .dat file.....

    I don't know if will help, but I noticed in a thread someone (@chefsuccess.com) mentioned, that, you need to use the restore to import the file.

    I don't use the software, so, I have no idea on the steps/procedure.

    Goodluck*Smile Disappearing DAT file on new USB Drive :)

    EDIT:

    Dam* those how-to web sites have everything.
