(many of them) on a Seagate 8TB Archive HDD.
The disk is only a year old and barely used (since it's just one of the
backups of my main data disks - and the primary disk another Seagate
8TB HDD broke just few days ago).
I have connected them via USB/SATA bridge... and when I now started
copying from the backup (which is sdb) to a fresh HDD I started seeing
vast numbers of these errors.
However, fsck, cp seem to do fine, and the data (as far as it has been
copied) seems good (I have sha512 sums of all of it).
Any ideas what "Unaligned partial completion" and these errors mean?
Thanks,
Chris.
