[sdiy] OT: how to save a dead Raided Drive?

Not all striped RAID controllers format and control the drive in the same
manner. My business partner found this out the hard way by moving two drives
in a striped RAID from one PC to another after a motherboard failure. The
motherboards both had onboard RAID support, but were from different
manufacturers. He lost ALL of the data on the drives as a result.

In other words, there's no guarantee that plugging them into that "sometimes
working Vista machine" will help any. I'd also be a little surprised if a
Mac could do anything with them.

Sounds to me like your best bet is to pay that $285 for the same unit that
you have. How much is this data actually worth to you? Less than $285?

You could also try contacting LaCie.
