Hey guys I have an iMac I purchased in 2008 (not sure what gen that is, but its the one right before the current models) in 24'' screen with 320GB hard drive. It began running anciently slow so I popped in the disk at startup to run Disk Utility and it shows that the hard drive is failing No more Warranty on the iMac so I'm gonna have to do myself. Does anyone have recommendations on what hard drive to get? The 320GB is plenty for me. The sad thing is that the hard drive failed before when it was under warranty and it happened again - I believe its a Maxtor so I figured I would go with a more reliable brand. I remember when buying memory for the iMac there was only select brands that were compatible. Would this also apply to buying the correct hard drive?
