I've found plenty of info talking about people having this problem, but I haven't found anyone saying what to do if you do. While this is not a critical server (used mostly for labs), it does have enough on it that I would *definitely* like to avoid rebuilding it. There won't be any actual data loss if I have to though, just time.
I believe I have logical bad blocks from a hard drive failing in a RAID 1 of my RAID 10. Similar situations from all my searching also reference it as a "punctured" array (but that also seems to be a vendor-specific term). The array won't rebuild.
Slot 1 started reporting predictive failures. We purchased an brand new drive of the same model (ST3500320NS), shutdown the server, replaced the drive, and booted it back up (non-production server). It reached 90% on the rebuild and started throwing unrecoverable media errors (slot 0 [remaining drive of the RAID 1] and slot 1 [the new drive] increment at about the same media error rate when this happens). We returned the drive for a new one, same issue at 90%. All cables have been re-fixed, just in case. A chkdsk with /f or /R hangs at the exact same file count of stage 4/5 every time (waited 1.5 hours with no movement).
- Controller ID: 0 Unrecoverable medium error during rebuild: PD 0 location 0x34c67621
