Your second paragraph contradicts the first, as if you had "written an IDE driver before", you would know that "LBA formatted" doesn't mean anything, and that LBA and CHS are just two ways of feeding the same numbers to the disk. You'd also know that reading a disk won't cause it to "lose" its data. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
