I think you are not going to recover any files that are not corrupted. You said you tried other software that failed to recover your files. Did any of the software find your files and were they also corrupted? 

 

I can't say this will work but you can download Partition Wizard here. Install and run the program. Start the partition recovery wizard. Do a Quick Scan. Does it detect any partitions. Highlight any partition found and double click it. Does it show your files? Do this for any partition found on the 2TB if you had more than one partition on it. 

 

Place a checkmark next to the partitions that showed files when you double clicked them. Press Finish then Apply. This should recover your partition but I cannot guarantee that the files on the recovered partitions will not be corrupted as even TestDisk failed. 

 

If a Quick Scan does not detect any partitions you can do a Full Scan but this will take a long time on a 2TB drive.

 

Edit: Depending on how important your data is you may have to use a professional data recovery service which can be expensive. One of the better ones is DriveSavers.

I haven't tried this method myself but check it out. Just make sure you are willing to take that chance before considering it

 

How to Convert/Change RAW File System to NTFS without Data Loss

http://www.easeus.com/resource/raw-file-system-to-ntfs.htm

The RAW drive can be caused by a number of reasons such as virus infection, format failure, accidentally shut down operating system, power outages, etc.

When you access the RAW drive, you will get an error message like "The disk in drive is not formatted. Do you want to format it now?"

If you click "No", the drive cannot be accessed. If you click "Yes", we will lose all of the files stored on this drive.

What that tells is do not try converting back to NTFS before trying to recover your data.

 

This isn't free: I didn't go back on-line to check how much it costs.

EaseUS Data Recovery Wizard Professional is a powerful data recovery software that can first help get all data out from the RAW drive. Then you can format the RAW drive to NTFS, FAT or other file system. Besides this, EaseUS Data Recovery software can recover deleted files, recover files from raw drive, recover files from formatted drive, recover files from lost or deleted drive, etc.

See if you can recover any files using PhotoRec or Easeus as comptrgy suggested but if you tried other recovery software and it failed I don't think you chances are good PhotoRec would also work.

 

Is it possible to pull the drive from the enclosure and attach it to another computer either using an enclosure or USB adapter? There may be a problem with the USB bridge card. Does the Buffalo external encrypt your files? I noticed it uses a WD drive (wd20ears). If WD made the enclosure for Buffalo it's possible it encrypts the data and the drive cannot be removed and placed in an enclosure. You may want to contact Buffalo to confirm this.
