I presume this is the right place to post this. Ever since I've had my computer it clicks a few times on startup/restart. Always been the way for years. However, on booting Debian 8 last night I noticed it did it a few times more than usual and stopped when the desktop had loaded. However, the boot to desktop speed was fine, very fast.
Normally I would think this noise is coming from the platters in the hard drive or the arm, but my main hard drive is an SSD. However, I also have two backup platter hard drives. Any idea what this could be? Could it be from the drives or elsewhere?
