Strange hard drive behaviour
I'm pretty new to Linux, currently running suse 9.3.
Something pretty strange seems to be happening on my machine, at least, I''ve never noticed it before. I have a permanently on braodband connection, which is why I'm a bit concerned about the following. Sometimes, when I am away from the keyboard and not using the machine my hard drive light will come on and stay on for some long time. Is this some kind of normal scheduled activity happening in the background or is it evidence that the machine is being hacked and the hard drive scanned? If it could be either, is there any way I can tell which it is?
