The correct geometry for an Adaptec is XXXX * 32 * 64, with XXXX being the number of megabytes for your drive (rounded down to the nearest megabyte boundary). You cannot really ``turn off'' translation for a SCSI controller, since SCSI does only know absolute block addressing, so *any* ``geometry'' (as seen from outside) is a translated one. -- 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. ;-)
