If that works, you should be able to repeat the previous process to completely remove the mirror. I don't presume to know enough about WD drives or mdadm's implementation to be able to answer that.

I re-added the removed drive to /dev/md0 and recovery began; things would look something like this: [email protected]:~$ cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : Note that the data on these sectors will be lost forever! $ hdparm -write-sector 1261069669 /dev/sdb /dev/sdc: Use of -write-sector is VERY DANGEROUS.

I don't understand what to do when you suggest doing an echo repair or verify. If you accidentally delete a file or a software bug issues a file delete or wipe command, the RAID 5 array will dutifully destroy the data on all drives. –David Schwartz If I come up against a similar circumstance again and figure anything out, I'll post the results here for posterity. Unhandled Sense Code The read errors were caused by a sync of a new RAID5 array, which was initially running in degraded mode (on /dev/sdb and /dev/sdc, with /dev/sdd missing).
