Eli5: What affect do power cuts really have on a computer?

596 views

If the computer is running and gets suddenly turned off by loss of power, what really happens? Is there damage that happens slowly or progressively over time or is it more of a risk that something might happen to the computer suddenly in any event?

Biggest issue is data corruption. Things that were in the process of being written to the hard drive but didn’t complete. Windows (or other OS) will make an attempt to fix it on reboot but it’s sort of a situation where it doesn’t know what it doesn’t know. Which is why you should never cut and paste, but copy and paste and then delete the source if you’re at risk of a power hit.
