I.e., a Really Old ESDI MOD drive, 2x280 MB, with an ESDI-to-SCSI bridge? > (aha0:2:0): "SONY SMO-F521-00 2.03" type 0 removable SCSI 1 > sd0(aha0:2:0): Direct-Access 311MB (637041 512 byte sectors) > > I'm using a 1304 MB double side rewritable Magneto Optical Disk with 1024 > byte/sector. Hmm, but the above information does rather look suspicious. It seems the driver got it wrong, it identified you medium as being a 600 MB one. Since this information comes from the drive, i would basically trust it. Are you sure your drive can handle 1.3GB media? (Mine cannot.) The drive is a good candidate for the `od' driver, btw. Our kernel cannot handle media with 1024 bytes per physical sector yet, in particular ufs falls over. I've got patches sitting in my queue for too long, from the author of the `od' driver, to fix this, but i haven't had the time to review them. If you promise to send me a failure or success report, i could send them to you. Be warned however: it will be some work, and you will have to run a -current kernel in order to experiment this (most likely, that is). -- 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. ;-)
