This is really an IO error.  Probably due to hardware problems.
See in the system logs for more information. (/var/{adm,log}/messages
or syslog).
Try cleaning the drive.
Push on the scsi connectors.  Unscrew them/ screw back in.
Move all power cables away from the scsi cables (cross only at 90°).
Sacrifice a chicken or a goat (depending if you're on scsi2 or UW scsi).

This is from Amanda version 2.4.2p2 (Debian package for Woody), so I'm a
little behind the times.

tapetype from that version would take a few days (and it will not
warn about compression on or off).  Upgrading would be nice (after you
solved your hardware problems).
