I currently have two Hard discs on the same IDE channel thingy. One's 120GB, which I use for my current OS. On the Slave, I have a 40GB harddisc, which i don't really use at all.
It seems logical to me to move the Swap over to the 40GB one, especially as my Computer seems to have gotten very slow recently (would buy new RAM, but i'm looking for a cheapass solution here ;) ). Are there any disadvantages to that?
