JBOD ate my drive

I have a Galaxy Dual-Bay JBOD enclosure with two 1TB drives in it. Then one day my 160GB portable USB drive got sucked in by the JBOD and made useless (would no longer mount). This was on a MacBook Pro running OS X 10.4.11. Galaxy support denied their enclosure could do this until I told them it renamed the portable drive "2.0 TB Media" and after a pause they say, "well that shouldn't have done that." I guess the name rung a bell with them. The physical size of the drive was also showing up to be little over 2 terabytes (935GB X 2 + 160GB I guess). I could see the name and the size in the app Disk Utility but it still wouldn't mount nor could I repair it there.

I have tried Data Rescue, Stellar Phoenix and FileSalvage on the Mac and SpinRite 6 and R-Studio on the PC (pulled the drive and hooked it to a 2.5 to 3.5 adaptor cable). While the programs on the Mac can see the drive they get to 128GB and just bog down. I've left them run for a week and a half and the indicator said they still had like 40,000 hours more to run. I bailed on the Mac tools thinking a low level tool like SpinRite would be better but it and R-Studio don't even see the drive.

Last note, I had tried the Mac recovery tools with the original configuration of the JBOD and portable drive plugged in but the tools only saw them as separate drives and I got the same result as if they were single drives.

Any thoughts/help is appreciated.
