They're raid 5. We were using a software raid to combine them all together. 1 hard drive went down so we replaced it and now the system won't boot. We have used a Knoppix boot cd to get into a linux system. We can see /dev/sda1 and /dev/sdb1. However, /dev/md0 cannot be accessed. Is there a safe way to create the software raid from the cd to see if maybe mdadm on the original system got corrupt? any help would be greatly appreciated. Sincerly, Ken
