Use of FreeFileSync gives HDD Errors

[trucken]

Hello,

Since last versions while use of FFS I receive after syncing some bizarre hard disk errors in logical structure.

What I receive from Windows 10: it is information, that "we find some errors on HDD".
When I check Journal, I see, some files has missing parts or occupied places signed as empty etc.

What I receive from Explorer view: I have e.g. different files, which have the same content, total shredded files.
For example, today I synced 2 different mp3 and several m3u files in my collection from HDD to other HDD.
Because I observe the problem, I have checked HDDs before start.
After syncing I found, that both mp3s playing the same content: from the second file of that both files I synced. Both files still have own name, so why I find the error visually, because the first file displayed in Explorer the thumb from second file, not it own.
After a while Win recognizes errors in HDD logical structure. Some of syncing m3u I find after repair in typical 000.FOUND folder.

I have observed before on my SD cards, that I receive that problem for sure at the moment, when FFS stops responding during syncing, freezing for a while during syncing and starting again or I stop the app during syncing (especially or SD cards). After that my phone started playing different content than describbed via file name from files, which where syncing at describbed above moment, so it is how I find the error.
Now I have problem with external USB3 HDD.

I've changed disks, computers, cables. Problem returns from time to time, last time 1 month ago, 2 weeks ago and now. Please, check the app.
