When playing a recorded TV broadcast on my PC, I notice heavy disk reads,
judging by the light on my HDD.

Will this stress the disk, or lead to premature failure?

Thanks very much.

I doubt it - that is what they are designed to do. Hard drives are rated
with a MTBF - mean time before failure. This is not affected by the type of
files you open and close.

I believe that the most strenuous activity for a hard disk is spinning up
(power on).

If they're heavy, you might need to defrag the disk, get a
newer faster drive, or record at a lower bitrate. Depends
on specifics but generally if you notice no playback
stuttering it's probably fine.

Of course it'll stress the disk, everything that reads and
writes stresses it, compared to having your PC turned off.

That stress is going to wear it out over several years of
use... what a hard drive is meant for, writing and reading
files.

No premature failure, there's nothing premature about
wearing out a mechanical device by using it. Similarly,
driving your car around town is a lot more stressful to it
than leaving it off and parked in the driveway, but that's
the point of having a car.

I love you, man!
 
Obviously when you record a TV show it has to be stored somewhere, and it is
stored on the Harddrive. So to view the show your harddrive will be
constantly running. This should not appreciably shorten your harddrive's
life.
