Sounds like you are stuck in DOS mode. For an undelete in a real OS, beyond the Windows 'trashcan' desktop GUIs implement, it should be a "Do or Do Not, there is no try." deal. Either have real file versioning, snapshots, etc. or don't bother. Snuffling around on the platters for raw blocks and just blanking out the first letter of file names are bad ideas best left in the dustbin of history.
undelete through versioning is bloody useful. However it's no substitute for a tool that tries to recover data when there has been a failure. When people are writing filesystems they often don't think about how they could make it easier for themselves or others to write a tool to recover corrupted data in the event of various failures (both software and hardware).
Personally I don't see the loss of logical volumes as a big deal. I've never understood the point of them when you could just have a fast index in the first place.
