Deleted file retrieval
Can a file that's been deleted and subsequently had all it's sectors
overwritten with new data be restored to its original content? My
intuitive sense is that it cannot, but I seem to remember a thread on a
different news group where someone claimed that even if a file had been
completely overwritten numerous times, it could still be retrieved.
In light of above, is there a poor man's way (meaning without
specialized software) of rendering a deleted sensitive file
unretrievable by overwriting it's data with another file of equal or
greater size?
