My RAID 5 server got severely corrupted by windows checkdisk.
R3 data recovery did their best to recover the data and got a lot of files back for me - but a lot was also lost. I doubt anyone else would have managed to do more so better than I feared (rather than better than expected).
R3 are very organised and efficient and provide pretty much 24/7 support. They will show you exactly what they can recover before you have to pay up. Data returned on a USB drive with the original drive delivered back to you in "as received" condition - all included in the "more than I'd hoped but less than I'd feared" cost.
My advice if you have a drive crash is touch nothing and get it to R3; then stand back and let them do the job.. They are totally trustworthy and you won't be ripped off.
