The only reason I can see for supporting 512byte reads is to allow them to to be used as system disks without requiring a BIOS update. I suspect that the only reason that the BSD systems don't support sector sizes other than 512 is a lack of test media. Indeed someone has recently gone through the netbsd code getting it to work with (IIRC) 1k blocks for a specific disk. With a test sample the ffs support would be fixed in a few days, and probably backported to recent releases within a few weeks. No one using windows will care :-) you could lock the ATA bus a few times a day and they'd just reset and continue. :-) David -- David Laight: david@l8s.co.uk To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
