Interesting, and ironically appropriate, sig, Mark. No magic is required. Simply wipe each disk by writing all zeros with dd. You can do all 4 in parallel. This will take a while with 1TB drives. If there are still SATA/NCQ/etc issues they should pop up while wiping the drives. If not, and all dd operations complete successfully, simply create a new RAID 10 array and format it with your favorite filesystem. Then restore all your files from your backups.[1] [1] Tact is the ability to tell a man he has an open mind when he has a hole in his head. -- Stan
