- There is no facility in mediainit, guru mode or otherwise, to specify a
- SCSI disk sector size. The s800 and s700 SCSI disk drivers simply issue
- a FORMAT UNIT command and do not support modifying any of the various
- parameters on the Direct Access Device Format page (SCSI mode page 3).
- If you're using a s700 and your disk mechanism allows changing the
- sector size value on mode page 3 you could write your own application to
- do it using the SCSI device control driver (see scsi_ctl(7) on a 9.0
- system).
-
- I'm curious as to why you want to use a sector size different from the
- default chosen by the disk vendor? And how many other folks reading
- this want to do the same?
