My 7.5-year-old G4 Dual 500 has been working like a charm ever since I got it in Dec. '99. Finally, after all these years, the HD died. Luckily I have everything backed up to an external FW and I'm using that as my boot drive now. I'll be getting a new iMac after the redesign comes out, but I'd still like to get a new internal drive for the G4 now and keep it as a 2nd computer after I get the iMac. I know the current drive is ATA, but other than that I know nothing about replacing it. Do I just look for another ATA drive and plug it in when it arrives? Are they plug and play, or do I need to know more about it? Is there anything in particular I should know, or is it typical Apple simplicity? Any advice would be greatly appreciated!
