Especially if you get larger drives, and you can identify and copy just the three good disks, then don't bother with the bad one. Just partition the new fourth disk the way you plan to do it, and then add it back in. You can then use the utilities to re-arrange the other drives. Or, and it's a bit more work, partition the new drives the way you want, and ddrescue the old drives partition by partition, rather than a drive at a time. But it'll save moving the partitions around later. Cheers, Wol
