I am about to sell my 12" PB (in my sig) and want to make sure the HD is nice and clean of all of my data before I sell it. I want to delete the HD completely, then do a fresh install (so everything is nice and neat for whomever buys my computer. I am sure there must be a thread like this already, but I couldn't find it. I was thinking about hooking it to my new PB in target disk mode, then using disk utility to erase the old PB. Then put in the original CD for the old PB and load everything fresh from there. would this be good? Thanks!
