My guess is the 250GB id causing you problems, remove that drive from the array and rebuild the array if needed, and all should be well. If you really want to use the 250GB drive, make a 200GB partition on it, and then add the 200GB partition to the array and you are free to use the remaining 50GB for whatever, maybe LVM. ~J Joseph Key wrote: > I have a AMD system with 3 200G and 1 250G hard drive arranged in a 4 drive > RAID 5 array.
