responding 2 nick: > WHY do you want to mirror root?
i do not like software raid at all and i even more dislike ide-raid (regardless whether it's sw or any other hw-raid). but sometimes you use hw where an hw-raid is not supported (even if there's a controller on-board...) and that's my reason for trying and using sw-raid like raidframe because it is better than nothing... really talking 'bout raid1 like i want it to be: having redundant power, redundant disks w hotplug, scsi320 at least and a good raid-controller-hw with a really smart bios handling any problems... i totally agree with you that scsi-hw-raid w hotplug support is definitely what you want on any production server. but if it comes to a development server or anything you just test on, you'd want to mirror root also, because you don't have to take care for your "2nd chance". you just throw the damn bad ide-hdd out of the window and the other one would bring up your system again like it was 10 minutes (add time for hangup, shutdown and some coffee) ago.
