hard disk wiping?

(1/2) > >>

solarismka:
I was wondering if there is a program out there that can wipe the free space in linux, including the swap space?

I googled but all i've found are programs that erase a file and/or directory not free space.

Any help would be great!  :D

flap:
You want to wipe all the space unoccupied by files? That seems like an odd thing to want to do, and I don't know of anything you could use to do it. I suppose you could create large random files to fill the remaining space on your disk and then delete them.

Try searching freshmeat.  I also know theres a program in Windows called Eraser that can do this - it's covered by the GPL so there may be a port.

If you mean shrinking your linux file system:
Try Diskdrake. Just make a bootable floppy from Mandrake and include Diskdrake (as far as I know the best partitionning program).

I'm pretty sure he doesnt, he means wiping.  Writing random 1's and 0's over the free space to ensure it cant be read by anyone with "recovery" equipment (like the fuzz, or people interested in getting medical records off hard drives etcetera...)
