I think you missed my point - I did that. It worked fine. I was able to recover about 30% of the files on the drive that way. There are another 30% in "$Inodexxxxxx" files, and the other 40% are not there at all.
The problem is that, if this ever happens again or for other people that don't have a (for example) 16 Terabyte spare drive laying around, can you help me configure R-TT to configure and interpret the original drive set?
RAIDFRAME is a software RAID5 configuration - when you set up the drives, there are a couple of ways to approach it. The first is to simply stripe the drives together, which would make sense if the R-TT software were correctly interpretting the Parity Blocks on the drive. The "RAID5" approach seems to work as badly as striping, since I can't figure out a way to specify where the parity blocks are in the sector set. Since you guys aren't using (or actively ignoring) the parity anyway, it would seem like a relatively simple thing to be able to specify in a RAID0 set how many sectors there are in a stripe and where the parity is.
LIke I said, I'd be glad to work with you guys on this. Being able to access the original damaged RAID array and then make reasonable changes to the mirror (in my case) might make it so that I can retrieve more of these files.
