Time Machine Recovery (after data recovery)

Several months ago, Disk2 and Disk3 in my 2007 MacPro 1,1 (OSX 10.7.5) became unreadable by the computer. To make matters worse, the Time Machine external backup became equally as unreadable. All at the same time! Drive 1, with the operating system, seems to be unaffected. The two unreadable drives showed up as "media" in disk utility, but didn't show up in Disk Warrior or any other similar programs (partition repairing) using the "terminal." I sent the Time Machine drive (WD Mybook Essential 3Tb) to DataRecovery.com and they found no phyical issues with the drive. There was, however,"Data Corruption in the file tables and data area" (according to the evaluation report). This was corrected and the TM drive was supposedly completely recovered.

Upon receiving the external drive (now replaced by a newer 3Tb Mybook), I replaced disk2 and disk3 with new 1TB drives (formatted with a single partition) and tried to perform a restore for these two drives. No such luck.....The drive was readable by the computer but would not actually enter into "Time Machine." I examined the actual drive and found an inordinate amount of Unix executable files, especially when going into the individual backups. The drive does show that they recovered 870Gb of information, but nothing seems to be readable much less recoverable.

I'm wondering if there is a workaround for any of this or whether I should contact the data recovery people to resolve this. I appreciate any help on this as it's become expensive and a bit deflating.......I still hold out some hope, though. Thanks. The drives were most likely corrupted by a generator that kicks on once a week (automatic maintenance) and temporarily cuts power long enough to turn the computer off...I've since gotten a UPS.
