Is it a single drive that's the destination or multiple drives in an array?
Single mag media drives that do that - what I do is assume they are bad -
backup all data on them - then if I am not trusting the software I dd zeros
over the entire drive, then run SMART to see what the drive reports.
SSD's I don't dd over the entire drive. Instead, I run the manufacturer's
SSD utility. Most decent M.2 SSD's have them. Unfortunately, many are
windows-only. As of yet I have not committed a production Linux or FreeBSD
system to SSD and I have little inclination to do so, since in general I use
those as servers where having it boot fast is pointless.

Subject: [PLUG] Error reading files
Last Wednesday I copied a large set of data files to a different partition
on this desktop host. Since then my dirvish backup reports show errors
reading the copied files; files in the original location are backed up just
fine. Here's one day's report:

There are no changes to these files other than their presence in the new
location. File sizes are the same in the source directories.
The destination partition has available 85% of its capacity.
How do I find why these errors occur?
TIA,
Rich
