Repairing corrupt volume information on external drive

Hi All,

I have an external drive here that used to be mirrored with another
recording backups of some of our workstations here. The machine
crashed a few days ago and no volumes can be found on either of the
two mirrored drives anymore. Every time I try to connect it to a
different system, it comes up with an error stating that no volumes
readable by Mac-OSX can be found on this disk. The drive was never
used on anything except a Mac. I have tried different disk utilities
including Disk Utility, Tech Tool Pro, Drive 10, Diskwarrior, etc.
only to find that the only one that even sees the disk is Tech Tool
(and finds no errors on it) but none of them can see the volume.

Can someone please recommend a solution to recovering data from this
drive. Maybe software that can rebuild volume information for a
drive without erasing everything? Thanks in advance!
