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.
