Random Hard Drive Spin Ups
I have a crappy old laptop that is on its last legs, but I use it as a print server (and as a linux server) on my network - so it is fairly useful to me.
I leave this laptop on all the time, but only access it over my network occasionally. As such, I thought it would be nice to use HDPARM to get the hard drive to spin down after about 30 seconds to prolong the life of my hard drive.
This works, but for some reason about every two - three minutes the hard drive mysteriously spins up, whirs for about thirty seconds and then spins down.
I thought this may have been due to the fact that I was almost totally reliant on swap space (only had 64MB), so I upgraded to 200MB - same problem.
Tried monitoring processes to see what is causing this, but to no avail.
