I'm familiar with the various undelete tools for Windows and Linux. Such tools may not exist or make sense for older file systems. Entire files would be great to find, but I suspect interesting fragments may be more likely. Running a Windows-based tool like Recuva on a hard drive leads to such a firehose of fragments if you choose the deep scan that examines all unused blocks. I've only tried the free version. Does the pro version give you a way to exclude all the dozens of OS file types that are probably not the user-made files that you want? And for the archaic disk formats, it would be good to have platform-specific methods of identifying fragments to guess their file type beyond executable and ASCII. Older run-length compression image formats may be more possible to recover than today's block-compressed images. - John
