I'm going to take the plunge and DIY (DIM?) but having a bit of trouble figuring out what drive would work. The drives in that model of Powerbook are ATA (and all the tech specks I can find on Western Digital are for their SATA drives) IFixit lists this drive: http://www.ifixit.com/Apple-Parts/160-GB-5400-RPM-Seagate-ATA-Hard-Drive-New/IF107-046 Which is a bit more expensive than a comparable drive on Newegg: http://www.newegg.com/Product/Product.aspx?Item=N82E16822148073 They are different models (the newegg seems newer. Which makes me wonder if the IFixit drives are all older models - which may be necessary and more compatible with older laptops) Will either drive work as a replacement? Thanks for your help!
