Hi,
We're having some trouble reading tapes from a SCSI DAT drive connected to
a Linux box running a 2.2.8 kernel.
The specs are:
Adapter: Motherboard AIC-7880
Tape Drive: SONY Model: SDT-7000
SCSI Driver: AIC7xxx driver version: 5.1.10/3.2.4
The st driver is loaded as a module. There is one other device on the bus
with the DAT drive - a NEC CDROM drive. The Bus is terminated with an
avtive terminator on the cable (cabling shipped that way from Dell - it's
a Precision Workstation 610).
We can write tapes, apparently without trouble. No error messages. But
we can't verrify the contents of the tapes by reading them. When we try
we get in /var/log/messages:
May 17 16:37:11 ceres kernel: st0: Error with sense data: Current
error st09:00 : sense key Medium Error
May 17 16:37:11 ceres kernel: Additional sense indicates Medium
format corrupted
over and over again. From dmesg we get:
st0: Error with sense data: Current error st09:00: sense key
Medium Error Additional sense indicates Medium format corrupted
over and over again.
We've tried several differnt tapes from two different vendors. We have no
other DAT drives with which to attempt to read the tape.
Can anyone help?
Thanks,
Chance
