Gonna jinx it, but I've had a good run with drives lasting eons, with
the exception of several ones failing in an iMac (the same machine). 
And it's such a pain to change the drives buried within that hardware.

Also, that iMac has much less use than any other PC, here.

I have some 1980-1990s Amigas around here that still work, though there
is one that needs a slap to get the hard drive to unstick and spin up.

I did pull apart another completely stuck drive, and found that the arm
that tracks the heads over the single disk platter is a y-shaped fork
that holds the heads either side of the platter moves too far into the
centre of the drive, and the centre of the Y branch of the fork grabs
the disk platter.  I always thought the head arm should move the other
way at shut-off and stay off the platter.
