RAID 5 recovery with a single disk?

[Paul M. Dyer]

I recovered a RAID-5 with 2 disk failures once.   There were 5 disks in the RAIDset.   It was just luck.   Pull one of the failed drives out of the bay, wait about 1 minute, re-insert it, then pray.   If the light goes green, you did it.

The idea is that the disk is maybe not totally bad.   Re-inserting the drive, the controller sees it as maybe okay to use and just accepts it for good.   No rebuilding happens.

It worked for me once on a PE-2650.

I've got a 1750 with a PERC 4/Di that suffered two drive failures in
quick succession, and now I have one remaining drive of the original
three.  I know it's a long shot, but do I have any chance at
recovering data from the remaining drive.
