I'm assuming you mean not spinning at the time, in which case I think two 
disks are essential, with regular (eg: annual) checks that they do actually 
spin when you want them to.

I've certainly had example of disks in machines which I've then stopped using, 
and maybe 3 years later decided to archive the contents of the drives, only to 
find that they won't even start.

Anyone who's worked with mag tapes, punched cards, paper tape, 8" floppies, 
CP/M, Pr1mOS, etc is already familiar with that problem :)
