Your only chance is if the file you "got" was smaller than what was
originally there.  IOW, if you overwrote a 10K file with a 5K file,
you *MIGHT* be able to recover the last 5K. (Assuming the remaining
5K weren't subsequently overwritten by something else.)

I'm not that familar with low-level utilities for Linux, but there's
probably something that's similar to Norton Utilities for DOS which
will read absolute disk sectors.
