I cannot speak to accessibility, but I can speak to the power of the tool:
TestDisk - Partition Recovery and File Undelete
If things were lost by accidental deletion then TestDisk will likely get them back. If it's drive failure, it might, and PhotoRec (which can recover more than photos) almost certainly can, though it's a grand pain to sort through the recovered files, as they do not retain their original file names if you have to resort to PhotoRec and you often end up with many duplicates since files get moved around with great regularity and PhotoRec will find all instances.
