A plug-in desktop hard drive thingy.
Something a complete n00b like me can plug into my PC and do a straight copy of my entire documents folder (ie. Music, video and pictures).
The theory is to keep it nearby and to have one recent copy of all my stuff . . . then copy another then delete the last.
My documents folder is around 40 Gig so, bearing in mind at maximum it'd have two copies (briefly) on it I'd need a 80-100 gig jobbie.
Or slightly bigger to allow for natural music expansion.
I'm not worried about compressing, converting or anything like that. I just want to do a straight copy and paste.
Fool proof . . . so even I can't f*ck it up.
