Some of you said that > the disks worked just fine with other OSes. Not all non IBM disks has problems, that was not the message back then, at least not from me. What I said, and still says, is that Maxtor and WDC has a bad reputation on making drives that can't work reliably with UDMA66, quantum has its share too but not so bad. IBM's on the other hand works as expected... > I'd like to know if there has been a change in status of the UDMA66 > code. Not really, and it wont solve your particular problem, you should just run that disk as UDMA33 and it should work... -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
