I've tried running stinit manually before doing anything, and it says that
it has inited four drives (the ones in the library).
This is what it writes to the dmesg buffer:
st0: Drive buffer default set to 1
st0: Normal timeout set to 800 seconds.
st0: Long timeout set to 14400 seconds.
st0: Mode 0 options: buffer writes: 1, async writes: 1, read ahead: 1
st0: can bsr: 1, two FMs: 0, fast mteom: 0, auto lock: 0,
st0: defs for wr: 0, no block limits: 0, partitions: 0, s2 log: 1
st0: sysv: 0 nowait: 0
st0: Default block size set to 0 bytes.
st0: Density default set to 0
The same is also written for the remaining three drives.
This doesn't seem to make a difference to the behavior I'm descriving.
I will include the modprobe.conf at the end of this email.

The "st0: Incorrect block size." appears after I try to mount a tape in
the drive. This does not appear after I've run the mt -f device status
command just before inserting a tape into the device.

I don't have a /etc/modules.conf file. But I guess /etc/modprobe.conf
should do the same thing. Can't see it there though. Based on the below
file, should I just enter what ypu've written into
/etc/modprobe.conf.local ?
