As I understand it, all the 64MB EARS model drive have the WD Advanced Format eg 4k sectors. I don't have one and I'm pulling this (from the depths of memory || out of my ass), but I think those drives also have something funky going on where they report normal 512 sector when in fact they do have 4k ones. Either way, it wouldn't hurt to align on 1MB boundaries. -- Adam Vande More _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
