First thanks to cgsecurity for making this suite - awesome work!
I've ran into a problem, and I'm getting the same result on both Windows and Linux.
I've taken a dd img of a drive from an old apple laptop I own. I'm trying to recover data from the "Apple Core Storage" partition. I'm aware that there's a HFS+ partition wrapped in there, and that I need to do a calculation to set a limit on mount. However, TestDisk isn't giving me the response I expected as can be seen below.
1) On loading up an image with TestDisk I get the following:

2) So, I proceed with a quick scan with the following result:

You can see that the middle partition, the one I'm interested in, is not listed.
3) I proceed with deeper scan and I get:


4) I tried PhotoRec to see if it would recover files (to determine if the drive was encrypted), some files were recovered but as far as I can tell they were unreadable. I don't know what this means (Is PhotoRec trying to build files from encrypted mumbo-jumbo? Is the drive simple half-dead?)
Can anyone think of anything which may be causing this?
