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.

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
