I've been considering replacing my iBook HDD and would like to know if anyone has any advice... What kind of drive can I fit? Will any 2.5" ATA do? Do I have to use a 4200 RPM one or can I use 5400 RPM drives and can I fit a 120GB drive? my iBook is a late 2005 12" 1.33Ghz. Any advice or suggestions as to what make/model drive to get?
