Re: Problem detecting HP Tape Drive



I did, also tried loading st module manually.
modprobe sym53c8xx

but /proc/scsi/scsi is still empty

modprobe st

and in messages just mention the st module with a certain offset is
loaded, nothing about the tape detection then also tried "mt" utility
to send some commands to the tape, but nothing works!??!?!
