I got this problem last night.
Windows XP prompted me that i have some corrupt files on my external usb hard disk & to perform check disk utility.
I ignored the message & worked on this hard disk & when due to some reason i restarted my machine at this time the windows automatically started scanning my external hdd.
One of your disks needs to be checked for consistency. You
may cancel the disk check, but it is strongly recommended
that you continue.
Windows will now check the disk.

It was deleting some index thing & I can see it was going through each & every file & folded presented in my external hdd.
Now when it launched the desktop I noticed in my external hard disk that many files are removed from there original place & moved to a hidden folder known as found0 where there are around 500 sub-folders with all files scattered between all of them. This found folder is about 30gb. Now i don't know if any data is deleted or not IF yes how to recover such data?
