Well, it's been a long time since I fooled with DDS and Travan tapes,
but I do have the OEM Manual for the HP 35470/80A DDS drive, so it may
shed some light.
When you encounter the error, how long do you give the drive to recover?
Do you have the sense bytes from the read operation?
On the DDS drive, the error recovery can be quite lengthy, upwards of 6
minutes. If it fails, the manual is unclear if you can simply skip to
the next block or not, but that might be worth a try (use the SCSI
LOCATE command).
HP acquired the Colorado line, so there may well be OEM manuals around
from Colorado that better describe the operation of
your particular unit.
