hey guys, my friend told me to take a look at his powerbook G4 and his hard drive needs replacing. being that i am relatively new to the Mac scene i am only familiar with the Macbook and Macbook pro generation. After doing some research online i picked out this hard drive as a replacement: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3169381&CatId=2678 I just want to make sure this will work in the powerbook before i go ahead and get it. he has the 1.67ghz, 1gb ram, aluminum Powerbook G4, 15" Thanks. if thats the wrong one can you guys please suggest one that will work. Or if there is anything at a better price with the same or more capacity i would appreciate that too.
