Try running a long self-test on the drive (megactl -T long a0c0t0). If
it fails that it will be worth replacing it.

I'm assuming that that drive is part of a redunant RAID. Be aware that
if the disk is failing, a long self-test may turn up enough problems for
the PERC to knock the disk offline. If you don't have redundancy, back
the system up first...
