I have had a couple of disks do that, but only after showing some
signs of failure beforehand.  Like one that was sticky starting and
needed a quick thump to spin up, after about the second 'start with a
thump' I copied all the data off it.  It carried on working in
non-critical roles for quite a while after that.

I've also had a couple which have developed a few bad blocks before
rapidly deteriorating into uselessness, again I've had ample time to
remove all imprtant data before the end.

That's true but I'm very rarely disk performance bound - in fact I'm
very rarely any sort of performance bound except the speed of my ADSL
connection.  Speeding up either my processor or my hard disk would
probably save me 50mS per day!  :-)
