But they weren't the only ones - just perhaps the biggest volume vendor, 
generally for good reasons.  Name someone that hasn't shipped a bad 
drive - that we can afford.

Besides, single drive failures should really be the least of your 
problems because they are common enough that ordinary OS's and 
controllers have simple techniques to deal with them. But there are a 
near-infinite number of other things that can go wrong that you also 
need to be prepared for.
