I've once posted a /usr/share/misc/scsi_modes definition for the mode page 0x10 (?) in this mailing list. Using this, you should be able to edit the compression field in the mode page. Alas, none of the drives avaible to me did really let me edit this field, so there are certainly other problems around. (I've trashed my archive of freebsd-scsi, so i cannot repost this message now. However, you should be able to dig it up in the mailing list archive on freefall, or via the WWW server.) Once we know that it works, adding it to the ioctl(MTIOCOP) and to mt(1) is 5 minutes of work. -- 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. ;-)
