AFAICT the way most 'recovery' places work is that they'll recover data if there are no issues and any ordinarily skilled IT tech could also recover it. And then otherwise they'll claim it's unrecoverable. Sometimes, it seems, they'll even just claim its unrecoverable because they didn't happen to have or find a compatible drive when that's all that was needed.

I've recovered data from media a number of times a recovery company said it was unrecoverable with no particular difficulty.
