Not typically; there isn't much writing going on, this is true.  Are you that 
cash strapped that a $75 UPS with a serial port is out of your budget?

HDDs don't fail because they lose power.  You get data corruption when writing 
and losing power, and you get filesystem corruption if the filesystem/OS is 
postponing writes to increase write performance.  That's not HDD failure.
