What's the model of the flash drive?

You're concerned about 20GBs a day, really?

I am sure that it’s not because of another program or Windows updates.

there is literally no other way

TRIM doesn't write to the drive. It's a completely different operation.

I'd stop and ask on r/datarecovery, consider professional recovery. Might be a mechanical issue.

Same answer as the last time you posted https://www.reddit.com/r/datarecovery/comments/186yhtt/how_do_i_repair_this_corrupted_chunk_of_data/

Cloning, but only with proper software. ddrescue or HDDSuperClone. Can't be done under Windows due to Windows limitations.

by "bad block" you mean a read error? what does smart say?

197 pending sectors, 5 reallocated

yes, this drive is cooked

Newegg never changes...

This should be only like 25GB (at 256kbps). Have multiple HDDs/SSDs with copies. Backup to cloud. Don't bother with optical media unless you have a BluRay writer already.

does it spin up? isn't showing up where?

It's definitely not the recent ZFS bug that others mentioned here. Simply to the fact that when corruption occurs due to that bug it cannot be identified, the filesystem is consistent.
