Try another few to make sure, but the lack of consistency suggest something
other than the drive itself, but its inconclusive at this stage.

Reading will involve accessing multiple index and datafiles, which may
provoke issues which dont occur when linearly reading files to copy them.

Thats error &D for old ST506 controllers. For modern controllers error &13
is an uncorrected data error, which means the sector data did not match the
checksum, which could either mean the information on the disc was corrupted,
or more likely as it passes a verify, that the data was ok on the disc but
was corrupted by a glitch while being read.
