You might want to try fiddling with the disk modes (LBA etc.) associated with the disks to make sure they're treated the same. There's also a reasonable chance that it's getting its information from the MBR on the disk; you would have to dd 0's over the first block of the disk and power cycle to experiment with this theory. -- \\ The mind's the standard \\ Mike Smith \\ of the man. \\ msmith@freebsd.org \\ -- Joseph Merrick \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
