Hi y'all Just wondering if I could get a bit of advice I have a Macbook Pro early 2011 which came with a 500GB Hitachi drive. I was experiencing poor performance in certain areas of the disk regarding file transfer speed a couple months ago, and after further investigation found that CrystalDiskInfo and HD Tune Pro (under Boot Camp) would report a SMART warning next to current pending sector. A month ago I upgraded to an SSD and put the Hitachi in an external enclosure. I would still like to use it for data. Today I spoke to Apple and their reponse was basically that they wouldn't help me until I put the drive back into the Mac (fair enough), but they dismissed my point about SMART errors in Windows, saying that they weren't a reliable indicator of drive health, instead referring me to Apple Disk Utility (which actually gives less information). They told me that I would have to take the Mac to an Apple store and get it assessed. After getting off the phone, I scanned the drive for bad sectors using Speedtools Utilities Pro and it failed at around the 85% mark. I know it is normal for drives to develop a few bad sectors over time but my concern is that they're not being automatically re-mapped. So I don't feel like I can trust the drive. Although I would like to have the drive replaced under Applecare I am loathe to spend time without my Mac if all they are going to do is refer to Disk Utility's 'Verified' status. Do I have enough evidence to support a claim for a failing drive? Should I try and get it replaced?
