Tejun,

I rebooted with the 4726 online during bootup, verified everything was
there by re-formatting the fs on each drive. I powered off the 4726 for
approx 15 seconds, turned it back on, and repeated the power on/off
again about 1 minute later.

The first 3 drives are accessible, but the 4th drive on ata1.03 failed
to be recognized.
