as root, dd if=/dev/wherever of=~/something Of course, it just contains pages (4KiB) of data. Since we can't tell what is in it, and therefore what you might look for, try running 'strings' on it and seeing if *any* text in the result makes sense. > I can't just mount it, right?

Ehm... right? > On this one, I'm in the dark - I like the sound of software suspend, but as Linus said a while ago, what people really want is suspend to ram. On my ibook, suspend to ram has worked for a long while without any funny requirements (just close the lid). On a desktop (or are you using a laptop ?) you need *something* to suspend it, and to make it resume. That part seems to be rarely discussed!
