laptop's hard drive turns on and off
I don't actually know whether it is a problem, this is what I want to find out: my laptop's hard drive turns on and off every few seconds. Even if I'm not doing anything. Is it normal?
I'm a little bit concerned that it might not be normal, and it is irritating - every time it turns on it emits a bip. Well, not the high-pitched bip, just the sound a computer does when it awakes from a standby, for example.
I tried antivirus, getting off the internet, etc. but it didn't change anything.
