Anything from no effect at all, to complete data corruption.

You protect against any bad experience with backups, and maybe a UPS.

Yeah, you’re absolutely right. I can just see all the files corrupt or something now

generally if the drive is working when the power loss happens, that is when data corruption usually occurs. not saying it won't happen with the drive at idle but generally when drive is reading and writing is when trouble happens. sometimes it only corrupts what your working on at the moment but full data loss can (and has) happen.

backing up important data is the way to go to ensure you got a copy if something happens.
