I'm looking for a used hard drive to put into my system, and basically it's been narrowed down to either a 30gb or 45gb IBM 75GXP, or a 40gb or 60gb Maxtor DiamondMax Plus 60. They're all about 1.5-2 years old. Can anybody give me any advice, and and pro's or con's of each drive? I've heard of problems with the 75GXP, but I'm not sure how common it is. I also heard that if you do have a problem with the 75GXP, when you RMA it, IBM will replace it with a better drive, like the 120GXP. Not sure if there's any truth to this. Any help would be appreciated.
