[QUOTE="Nethfel, post: 1017179, member: 89124"] Hard drives in general are rated in MTBF (Mean Time Between Failures) which is calculated on the average amount of time before the given part will fail. Hard drives tend to have huge numbers on their MTBF ratings, but that is just an average (and if you read this article, it discusses a Carnegie Mellon research project on accuracy of those numbers here: [url=http://www.dailytech.com/article.aspx?newsid=6404]DailyTech - Study: Hard Drive MTBF Ratings Highly Exaggerated[/url] ) Hard drives, as mentioned have moving parts and are one of the several most likely to fail first parts in an average computer (other parts most likely to fail early include CD/DVD drive, fans, power supply) Hard drives can fail within days after install or last decades (or longer) - I still have a few hard drives from the late 80s that work fine - and I've had brand new hard drives fail in a week. It can happen. Now, if you bought Applecare, then it should be a covered repair and you should already be able to get it fixed for little to no cost (assuming you have an apple store somewhere and don't need to ship it)! If you didn't buy Applecare, then at least laptop hard drives are fairly inexpensive these days and you could pick up a 500 or 640GB drive for <$100 (just looking at a list of laptop hard drives at tiger direct, the only one >$100 is a poorly rated seagate) [/QUOTE]
