How to isolate the Bad sector on a flash drive?

Question

Windows

Software repair is needed if possible (under windows)
there is a flash drive 2.0, there is Windows (hehe, working environment), these sectors are not visible with the usual means of chkdsk, etc. Only in ChkFlsh.exe Bottom
line: let's say we have a bad sector at the end of the hard drive. We would simply mark this area on the disk as unallocated and continue to live as usual
. With flash drives, I think this trick will not work.
So I think what can be done?
A flash drive was given by a friend with the words "file recording is interrupted (sometimes)"
If you kill a flash drive, you don’t feel sorry for it, so offer anything
Now the question is: how can I find this block, and how to delete / cut / hide / remove / get rid of, etc. etc.
Or is it not worth it because the controller will not write to a poorly readable block (skip no block)?

Answer 1

Or not worth it

Yes

because the controller will not record ..

where you think. flash and ssd controllers are very mindful (the topic is stoned on the network from head to toe), they dynamically redistribute real blocks of cells to logical address blocks. this is done in order to equalize the "wear". while the firmware algorithms themselves contain bugs

will not write to a badly readable block

will. This is where mistakes happen. otherwise there would not be this problem with this flash drive
