My son has an early 2008 Macbook and the Hitachi drive in it appears to be dead. I have read a number of postings on how to change the drive but my question is what drive can I use? The old drive is a Hitachi 5k250-160; 160GB SATA 1.5Gb/s. The stickers on it say that it has Apple Firmware 2007 on board. Can I replace it with any similar sized drive up to 250GB or does it need to be an Apple specific drive? Once I've put the drive in do I just load it from the original CDs? (I have not been using Macs for very long and this is the first time that I will be oing anything like this.) Thanks in advance.
