Sorry for the long post, but I can't access/use my tape drive with the tar
or mt programs and could use some help.
I'm running a 2.4.18 kernel on mandrake 8.2 (barebones install) and using an
IDE HP colorado 5gb tape drive. The drive appears to be recognized fine on
bootup (by looking at dmesg) and the relevant modules are loaded -- st,
ide-scsi and scsi_mod.
When I type any mt command, using either /dev/st0 or
/dev/nst0, I get a notice of an input/output error
and, sometimes, "mt: The device is offline (not
powered on, no tape ?)." Likewise, with tar, any
attempt to write to either /dev/st0 or /dev/nst0 fails.
Here are some examples. Let me know if any other info is needed.
WITH THE TAPE IN
[EMAIL PROTECTED] boot]# mt -f /dev/st0 status
SCSI 2 tape drive:
File number=-1, block number=-1, partition=0.
Tape block size 0 bytes. Density code 0x0 (default).
Soft error count since last status=0
General status bits on (10000):
IM_REP_EN
WITH THE TAPE OUT
[EMAIL PROTECTED] boot]# mt -f /dev/st0 status
SCSI 2 tape drive:
File number=-1, block number=-1, partition=0.
Tape block size 0 bytes. Density code 0x0 (default).
Soft error count since last status=0
General status bits on (50000):
DR_OPEN IM_REP_EN
TAPE BACK IN
[EMAIL PROTECTED] boot]# mt -f /dev/st0 rewind
/dev/st0: Input/output error
mt: The device is offline (not powered on, no tape ?).
USING TAR
[EMAIL PROTECTED] boot]# tar -cv /etc/passwd > /dev/st0
tar: Removing leading `/' from member names

tar: -: Wrote only 0 of 10240 bytes
tar: Error is not recoverable: exiting now

Any suggestions? First time setting up a tape drive in linux. and I have
been googling and groups.googling since 9am this morning trying to find the
answer.
I found this same question asked by some other people online but no answers.
Thanks in advance for any info.
