I've done a silly thing....
I'm at the start of installing Slackware and the setup offered to configure the swap space. I clicked yes, before noticing that the partition number wasn't swap at all. I hit <CNTRL>C immediately, but the damage is done.
I'm downloading http://www.tux.org/pub/people/kent-r...p/RIPLinux.iso
as we speak and intend to run testdisk.
