I think you’re absolutely right!

Good spot – thanks, Mike!

I’ll update the article accordingly.

I think your parameter is wrong. You should be using “sdelete -z”, which specifically zeroes free space. The -c parameter securely deletes content on free space by overwriting it, but does not guarantee to zero it.

Hey there,

when you get the error saying that the disk can not be registered, then you have to pass the UUID of the disk instead of the filename of the disk. In that case you do not have to edit any xml file.

Cheers!
