I'm a newbie, but I've been experimenting with mandrake since 7.0. I just brought up a Mandrake LE 2005, as a PDC for a blended linux, windows network. I want to move my Quantum 7000 DLT tape drive to box to back up the profiles and shared files. The lower level HBA driver is loaded, as is the mid level scsi_mod driver. The upper level device driver st.o is not loaded, but I can accomplish this using modprobe. When I run 'cat /proc/scsi/scsi' there are no devices listed and when I run 'mt -f /dev/st0 status' I get: /dev/st0: No such device or address.
The drive worked fine on WIN2000 server when I removed it last week, the scsi bios acknowledges the device on boot up. I have searched google/linux but not gotten anything that seemed to help. I have seen other 'cat' listings with the Quantum in them, so I know it should work.

Interestingly enough, I tried an old copy of mandrake move, which recognized the device when I used 'cat /proc/scsi/scsi'.
I guess I decided it was time to try a few other distros instead of wasting much more time on mandrake.
Next up: Suse 9.3 (install looks beautiful) Vector Soho and Mepis Soho.
