To: scsi Date: Fri, 26 Jul 1996 18:29:12 -0700 (PDT) X-Mailer: ELM [version 2.4 PL24] Content-Type: text Sender: owner-freebsd-scsi@FreeBSD.ORG X-Loop: FreeBSD.org Precedence: bulk A friend of mine just turned up with a Tandem disk drive (looks for all the world like an IBM :-) which has 514 byte sectors. He also has another one with 516 byte sectors. By all accounts we can change that to 512 with 'scsi -m 3 -p 3 -e', except that the driver gets all uptight about the 514 byte sectors and doesn't get as far as reading the mode page. scsiformat can report the format, so there must be some way to do read the information, and I suspect there's also a way to set it. Does anybody have any ideas? Greg
