So my buddy ran a Windows 'Disk Cleanup' on his WinXP machine that has undergone several upgrades over the years. He checked off the box to clean up 'Old Windows 98 and ME files' and it deleted....
EVERYTHING. Stupid Micro$oft.
Foo. OK, well, I can fix that. I whip out my handy-dandy deleted file recovery tool and I was able to recover almost everything. Almost, except for what is actually the most important - his Outlook Email database. The file is there and recoverable, but has a size of zero, not ~5Mb or whatever it should be. (Nothing has been written to this HDD since the delete to avoid overwriting the deleted files)
Now, I fully believe that someone who really knows what they're doing could examine the disk (NTFS) and recover that file sector-by-sector. But what about us? ;-)
My guess is that he's hosed, but I you were gonna tackle the problem, where would you start, and how could it be done?
