I'm, in fact, using a 2940U with a Python DAT on ID 6 with 2.4.25 on a PC next to me right now. Since you're working with a tape drive, I'll take this chance to advertise for bacula: http://www.bacula.org A free network backup solution. ;) Other investigatory things you should look at are 'dmesg' 'cat /proc/scsi/scsi' and 'cat /proc/scsi/(modulename)/*' Digging around in st.c and scsi_scan.c don't indicate anything strange, but, hey, try out ID 6 anyway -- this is the first time I've looked at either of those files!
