Question: Up to how many days will a hard disk last if it is turned on 24/7? I was planning to host my own web server on my computer. But then I had this incident where I was downloading <insert favorite anime here> from the torrent network. And I turned my PC on for 4 days straight I think.... And then on the last day, it was at 90% of the whole downloading process when suddenly my computer hanged. When I restarted my PC... I cannot boot anymore. So I reformatted it and then it started out cleanly. But then... All of what I have downloaded(8.57GB!!!) was erased!!!! So, I was traughmatized of that incident so I asked this question. Now back to the question, up to how many days can the Hard Disk be turned on before shutting it off to make it rest?

Answer: How long is a piece of string?  A hard drive can function indefinitely sans manufacturing defects or extreme heat.  I have 2 primary hard drives and 2 external drives running on my machine 24/7, only rebooting when a necessary update is required and things are fine.\n\nA hard drive is the only mechanical part of a computer and as such will at some point fail.  BUT when that is can not be predicted.  I would say 90% of the time it would work faultlessly until you are ready to change your machine
