Ok so i'm pretty sure my powerbook g4's hard drive is dying and i am looking for a replacement. i have looked around the web for a few days and newegg.com seems to have the best priced hard drives. i have searched the site and narrowed it down to this page of hard drive: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2010150380+1035907889+4026&name=%2450+-+%2475 here are a few questions though: 1. i am pretty sure all of the drives on this page are compatible with my aluminum 12' powerbook g4 (ex: connection type, mac/pc, etc.); if not plz let me know 2. i am only willing to spend between $50-$75; on this page all the hard drives are between that price range but they vary in size (60gb all the way to 160gb); so why are some of the bigger sized drives the same price as the smaller sized drive? does the company brand really make that big of a difference? which brand of hard drives are better than the others? 3. if you know of a better site where i can purchase a hard drive plz let me know thanx for reading and any help would greatly be appreciated.
