sorry for the long delay in replying - I had some traveling to do lately and didn't get a chance to really hit this forum
So after attempting some restores of files using a variety of programs, I managed to put a few in the attached zip file. I was unable to attach, say, the .jpgs individually as the forum was unable to determine the dimensions of the images (and they are not viewable in Windows)
I also attached some .mp3s that the restore program said were recovered but were not playable at all. I'm also going to try some of the apps fzabakar mentioned earlier now that I'm back home

Your files do not appear to be encrypted, but they do appear to be corrupt, or incorrectly recovered.

For example, here is a section from akeah.jpg:



Moreover, the sizes of the files and their compression ratios suggests that, even if some were encrypted, they are not MP3s or JPEGs.

if you can see the partitions and files on your drive but files has no valid content, then you may got infected by cryptlocker virus. I have seen similar cases.
CryptLocker is a file-based encryprion virus which encrypt all the data on your HDD.
Please give a look here: http://en.wikipedia.org/wiki/CryptoLocker

Hi that would have been a good call, and even I was thinking that was a maybe, except in his first post it was stated the drive failed in 2006 and was in storage until it was sent for imaging last year. I don't think Cryptolocker or anything like it was around at that time.

Since the MBR looks correct, then any decent software should be able to build the file tree for each of the partitions. Can you post a picture of the file tree structure for each of the partitions?

Also, since you said that wherever the drive was sent to determined the drive had an electronics issue, then that should have not had any impact on the logical structure.

You mentioned a cheap enclosure of some sort was used to connect this drive. Can you describe this adapter in more detail? What is the model, brand, etc?

Let's assume the drive is not encrypted. You can use software to run a keyword search in the RAW data for some common words that any set of data would contain. If you get no hits in the search for several words, the drive is likely encrypted.
