After two dead disks last month, another one died on me this evening. This time it was the 400GB external drive I have attached to my Mac Mini. The data on it wasn't critical, fortunately. I'd been loading it up with ripped DVDs from our collection, so the only thing I've really lost is time.
That, and my cool. Data loss FREAKS ME OUT at the best of times. Losing three disks in the space of a month has practically got me hyperventilating.
