Betcha 50c that is not the disks they have in the PVRs, though. I would guess WD greens.

Actually, keeping an HDD running all the time is not a bad way of ensuring maximum life. It's not the continuous spinning that causes problems - the HDD spindle bearings typically have a life of 250000 - 275000 hrs MTBF at constant optimal operating temperature. Apart from direct physical trauma such as head crashes (including bumps during operation) the biggest killer of HDDs and electronics generally is thermal cycling, ie the expansions and contractions caused by heating and cooling when powering on and off. This is why many devices have a "standby" mode in the first place - to keep circuits warm and reduce the dramatic shortening of componentry and circuitry lifespan caused by thermal cycling.
That said, modern HDDs are less prone to thermal cycling problems than in days of yore. Still, there's a reason most failures occur at startup/power-on, and it's related to the additional stresses this cycle places on drive componentry.
The whole HDD electro-mechanical unit has a typical MTBF of 40000-50000 hours, and most failures are in the head/actuator mechanism, which power-offs in any case don't mitigate.
This is why I prefer to leave my HDDs running 24x7. I specifically set the PVR's HDD to never switch off.
Cold start stresses can be enormous, especially for machinery designed to operate above ambient temp, including car engines. Most of the wear and tear in a car engine takes place between cold start and reaching operating temp for the whole unit.

Mmmmm.... with load shedding & winter on the way, might not be such a good idea to keep the HDD running all the time.
And I hope you don't get lightning a lot!

Lightning doesn't give a sht if something is turned on or not. It just jumped a couple hundred meters of air. You think a tiny air gap in a switch makes any difference?
