Even though that eMachine is only 8 months old, if it were mine, I would check out the label on the power supply while you have the case open. If that label indicates that eMachines are still using Bestec power supplies, I would plan on replacing it ASAP. Bestec power supplies are notorious for failing and taking out the motherboard and possibly other components when the go. Your power supply probably did not cause your present hard drive troubles, but it could fail at any time. My experience with Bestec power supplies has been that after 18-24 months you are risking your computer if you have not replaced it.
