My trusted iBook's HDD has died. How hard is it going to be to install a new hard drive for someone who's never been inside a computer of anykind in anyway? Is it as simple as 1) Buy new HD 2) Undo a couple of screws 3) Unplug old and replace with new 4) Return screws and power up? My data is safe on an external drive purchased a couple of weeks ago when the iBook began ticking and there's a new iMac on order so the iBook is being resurected as a spare. The reason for portibility is no longer an issue. It's a 3year old 800mhz G3 that will need a new battery and an AP card to be of use to me. Is it worth saving??
