Frequently reinstalling OS damage your machine?

As titlle said. Does frequently reinstalling an operating system damage your machine? Especially your hard drive.

nope

Answer no. It won't damage.

The hard drive is going to get a little exercise, but not much more than running the OS would give it anyway. If it's an SSD rather than an HDD then there's only a limited number of times you can write data, but the lifetime is measured in Terabytes or Petabytes - a few reinstalls are just a drop in the ocean.

No, the main risk of damage is to your sanity, especially if you're reinstalling under duress because the system keep falling over :)

As a matter of interest @Peyote why do you feel you might need to do a regular reinstall? I have a machine I regularly reinstall or restore a system image to, but that's for test and/or support purposes. What's your reason?

Hey @Bree thanks for the explanation. I work with 2-3 OS in one machine. Well sometimes i'd something wrong and got an error that cant be fixed without reinstalling it, since i got multiple OS in one machine its often for me to accidently overwrite the other OS (Windows) when reinstalling the OS (linux). Sorry for my english, i cant explain this more specific. And thanks again, cheers.

@Peyote, I understand you fine. My test/support PC has 3 OS too. I reimage it each time I want to switch OS to get a clean system to work on, it's quicker than reinstalling each time.

It won't cause any damage. I guess my question would be why you are reinstalling the OS so often. It might be better to use a virtual machine if you are doing a lot of testing.
