Hi, I need to securely wipe out a disk on a remote machine, but I don't have access to that machine. Therefore I cannot use the LiveCD+shred (or dd) combination. Besides manually shreding known data files, I am wondering if there is a (free) tool that can be used in my case. Thanks.

Wireless is configured per instructions in

Hello, I was asked if it is possible to zero unused space in ext3 partition?
