OK here we go. As I stated I am new to the whole Mac thing. I got a IBOOK G3 really cheap. I am a hardware tech for cell phones and bought this due to the logic board failure that the G3 is famous for. After fixing the video issue I love this thing. It was about 5 times faster than my desk top I use to program my phones with. I have been using it non stop for about 2 days now. Putting it threw its paces. Well I think I have problems....lol Stats...800 mhz 640 mb 30ghhd 1. The thing had not been updated for a couple years so I did this updating everything. Now for my problem... 1. The HHD started popping lastnight. I know what that means NEW HHD..Woo Hoo. 2. The net started going really slow. Another sign my hhd is going. My question is If I replace the hhd with a 320gig and upgrade the ram to 1 gig can I boot from my drive with the disc? Or do I need to copy my current hhd to the new one. I really would like to start fresh new everything. I want to put OS X 10.5. If I have to copy can I use my 320 external seagate I use with my Cell flashes to copy my HHD? I tried once and it said my seagate could not be modded? What am I doing wrong? I love this thing and dont mind spending the time to make it soar but right now my apple is rotten....Thank you in advance. 1. One more thing how hot should the bottom of this thing get. Its pretty warm.
