My QIC-80 drive is useless so far. : Is that why even though FreeBSD V2.05 MAKEDEV's *ft0 and recognizes : a Colorado 250Mb as ft0, but no tape or dump commands will work with : the device - "not configured" ?? Guess -- I've peered at something similar recently on NetBSD (which has moderately similar st.c)... If the drive quirks aren't set up right then the driver can go and do a mode sense/select combination to set the blocksize / density code. Some QICs get a bit upset at being asked to do this. (Quirks here including scsi inquiry string) What you could do is... get your st.c, and dyke out the mode select in the st_mount area... Failing that, get a scsi trace out of it and post it :-) cheers, al (not speaking for HP..)
