If you can get the disk to be detected I'd give the following program
a go, it'll completly wipe the disk clean, doing 6 or 7 passes of
writing ones and zeros to the disk, making it practically impossible
to recover any data on the disk.
There's another utility called "killdisk" that I've used in the past,
but I think it's only shareware.
Of course I'd check that using these types of utilities don't void any
warantee with the disk manufacturer.
