This has been changed in both -current and -stable, so use DD disks with care (ie skip the first 10 secs) > Correct me if I'm wrong, but in RAID1 it is essential to be able to take one > of the drives and boot from it almost as if it was singe simple disk.

Not at all, you have to use the BIOS to either switch off the RAID or setup a new fresh disks or whatever you want to do. If a RAID array is broken somehow, the driver wont attach it (a safety mesure so you wont blow up the remaining disks).. > Is it possible to query the driver to check, if the drives are OK from the > userland ? No. However I have an atacontrol thingie on the bench but its not ready yet, with that you will be able to control the RAIDs and other ATA related stuff... -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
