Constant disk access in Kubuntu
Since installing Kubuntu I keep hearing the heads in my laptop's hard drive as they go into resting position (as is normal when the drive isn't used for a few seconds), wait some two or three seconds and then are energized again.
This isn't a drive health problem (aka head crash); I've experienced those, and what's happening here is not the heads being reset over and over again, it's just the drive heads going to sleep and being woken up immediately afterwards.
I think this is causing much unneeded stress to my drive, and I'd like to stop it. Problem is, I've no idea what's causing it, or what to do about it.
