Hello, I have a serious problem with a RAID 1 hardware array, and I've been looking for a solution for months, unsuccessfully I had a 2-disk RAID1 array plugged to an Asrock N68C-S motherboard (which natively supports RAID); one day, I don't know why, the RAID configuration was lost and the two disks now show up as individual disks, and they are individually unreadable/unmountable by the operating system (Ubuntu 11.10). All I should have to do is define a new array using the two disks, on the same motherboard, but that would erase both disks! The only way I figured out to avoid losing the data is the following: - Define a new array using 2 empty disks; - Replace one empty disk with one of the actual data disks; - Rebuild the RAID, assuming I can choose which disk is the right source Do you think it could work? Or I should try installing Windows and try recovering the disk from there using some commercial software? By the way, the filesystem is ext4, not sure if windows can even read it Thanks a lot to anyone who may help! Mick
