Hmm, i forgot to mention that you need to actually turn it on using something like scsi -f /dev/rst0.ctl -d 0x7f (Don't ask me for the actual meaning of the possible numbers after the -d, i've never got a clue about them.) > Present Mode: Density = 0x45 Blocksize = 512 bytes That's probably a vendor density code for the compressed mode. Density codes 0x15 through 0x7e are marked as `reserved' in the SCSI-2 specs. I have no idea what the SCSI-3 drafts say about them. > Is there any possibility that the density table listed in > scsiconf.h is seriously out of date? It's the table from the SCSI-2 specs, and as such, represents the official standard. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
