Well, the hdd in my powerbook has finally died. Won't be recognized in disk utility, and when it was, it wouldn't repair or even verify. I kept getting the invalid node structure error. My AppleCare subscription has also expired about 2 months ago. So, I went online and found the following web site about opening up the Powerbook 15" (Aluminum) and how to go about replacing things in it: http://www.xlr8yourmac.com/systems/PB_G4_15_AL_takeapart/AL_PB_G4_take-apart.html#storytop Then, I went to tiger direct and found this hard drive to put in it: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1870093&CatId=2342 What do you guys think? Is it really worth it? What hard drive do you recommend I use? Is this better than going and getting it done?
