Like you found in the handbook, atacontrol is what you need and yes, you ca= n=20 do it without rebooting or droping into singleuser (if the drive hadn't=20 really failed but only had a "bad day" like trash on the bus which I=20 regularly have) > > The other option seems to be to reboot the computer and use the Fastrak > firmware to rebuild the array. Last time I tried that it didn't work for SIL0680 nor HPT372, but I don't k= now=20 about the promise. Give the handbook procedure a try! =2DHarry > > Which option is the most painless?
