I have a first-gen i7 iMac still covered under AppleCare. Over a year ago, I manually removed the HD and replaced it with an SSD, and have been running the original HD in an external enclosure ever since. Just recently, the HD appears to have bitten the dust as HDs are prone to do (no, I didn't damage it in any way during the extraction, and it's been stationary on my desk ever since). Is there any way I can get Apple to replace the HD under AppleCare given that it's not housed in the original machine any more? I assume that if I transplanted the dead HD back into the iMac, then schlepped the whole machine into the Apple Store, they'd identify the HD as the bad component and replace it, except 1) the original HD transplant was difficult and nerve-wracking enough that I don't wish to repeat it, and 2) hauling the entire machine into the store over just the HD seems like a big waste of effort.
