Magic Rescue is a file extractor that works with .img (image) files, like Foremost, extracting files you need. The difference between the two apps is that Foremost is finite, so to speak, as to what file types it will extract.... Magic Rescue can be configured so that you can extract ANY file type you need (as far as I know). Magic Rescue extracts files using what are called "recipes" (one recipe per file type) which are simple text files with a few lines of code that represent the file type you want to extract from the image file.
For instance if one wanted to extract a jpeg file, you would invoke MagicRescue in a command line like you would with ddrescue, using the recipe you need as an argument in the command line, to tell magic rescue which file you want to find/extract. There are a number of pre-configured recipes by default that are installed when MagicRescue is installed, but it lacks the .m4a (music file type) recipe that I need.. The magic rescue official help website says you can find the file type information you need to set up a custom recipe by using a hex editor to view the file header/footer information bytes which must be entered into the recipe. Then again it suggests to look on the Internet for some recipe that someone else may have come up with to avoid doing a bunch of work, if you catch my drift... Someone may have posted the recipe for an .m4a file somewhere and I was just wondering if anyone had seen one at any time, or if someone knew a database/website with recipes you can download.... I wanted to try to avoid messing with a hex editor to get the file information I need if someone's got a pre-configured recipe for .m4a files posted somewhere. That's all I was saying. I'm sure I can put the recipe together I need I just don't want to do the work
Ultimately what I'm trying to do is rescue .m4a files from a hard drive that the OS was reinstalled onto. Reinstalling the OS may have wiped out most of the files I need, but there is a chance the the reinstall did over write ALL the hdd sectors where the .m4a files are stored and I wanted to try to recover as many as I can.

It can be installed pretty easy... sudo apt-get install magicrescue
...just got an idea that will probably make the recipe building easier. I'll zero a hard drive and format the the drive....then I'll put a single .m4a music file on the drive so that the file info I need will be easier to find with a hex editor.. Once I get that info. it should be simple from there. But if you find a website or database with these recipes give me a holler...if you will
