A long time ago, possibly back in the MFM days with two cables per drive, a 
friend had a 24/7 machine and one day he came home to the sound of the hard 
drive hunting. He did a frantic backup (only MB, not GB or TB but transfer 
speeds were proportionally lower) and once he'd copied all the data onto 
another machine, he turned that one off. Once stopped, the drive seized and 
never went again, it must have chewed its bearings to paste.

I have a drive giving a couple of SMART errors, I've moved everything 
important off of it but it can stay for now. It was pressed into service as 
the only one I had to hand at the time of building that system so I don't 
know its full service history. In general, when in use my drives all stay up 
24/7 barring powercuts or the occasional exceptional deliberate power down. 
I have probably averaged losing one a year over the past 30 years, thinking 
of the big pile of defunct drives I smashed up a couple of years ago.
