Hi, OK here's the 411: I have an eMac and also an eMachines. Both are having problems. And both need to go in for servicing, and both will likely need to have clean installs. Before hand, I need to back up all my data. So, I am looking to buy a big external hard disk. I am willing to buy a bigger hard disk than I need (maybe 200-300 gigs so I can continue to use it in the future). My eMachines has USB 2 and my eMac has Firewire (it's an older one without USB 2). So I'll be buying one with both so I can back up to one drive. Now, I am I right in that I'll need to format the drive (or more likely leave it) in FAT 32 in order to use it with both computers? From what I have read on these boards, that format is less reliable than the Mac ones. Is it possible to partition it into two parts, one FAT 32 and one for the Mac? Is that advisable? What brand should I get? And finally where are the great deals? I don't want to pay retail! THANKS!!!!!
