What's wrong with the flash drive and the file?

Question

Data recovery

Good afternoon

Please let me know. There is a file on the flash drive, according to the last modification date, it can be seen that it was not overwritten, but when opened, it gives out this:


What can it be, is it possible to get the original file data?

Answer 1

What could it be

With a certain probability, the flash drive is kirdyk :(
Also check what is the situation with the rest of the files.
If some files look better, then try to open them after copying to the hard drive, you can also correctly remove / insert the flash drive a couple of times, copying the files both times, and then compare their contents in a hex editor.If
it differs, it's not good.Although not all controllers will give different
data.By the way, since you know how to use a hex editor, you can compare the drive images.Also
try to go through the flash drive with a data recovery program, which itself must be on another drive.I traditionally offer free R.saver: https://rlab.ru/tools/rsaver.html
Suddenly it turns out to restore previous revisions of the file or something like that.

is it possible to get the original data of a file?

More likely yes than no, but not at home.
With a high probability, you will need to contact a specialist who knows how to work with memory directly, bypassing the controller.
