One Maxtor, many years ago. I have continued to use Maxtor drives; none have died since.
The death of that drive may have been related to a power supply going bad -- didn't discover that until later when the PSU failed completely. Luckily, the drive gave me about a week's warning, during which time I was able to extract all my data except for two files I didn't really need anyway.
At work a few years back, we had an entire lot (I would guess 50 to 100.) Western Digital HDs fail after they had been installed in rack-mounted PCs (transaction processors) and shipped to the field. They all had to be returned. I don't know what model these drives were.
