Monitor your drives to extend their life
The problem is that modern laptops often have very aggressive power setups by default to, theoretically, guard against damage and reduce power consumption. But in doing so they may cause your disk drive to load/unload at more regular intervals than is reasonable.
These are typically set by the hardware manufacturer. Ubuntu doesn't overwrite these by default which is perhaps where the problem comes in. Hardware manufacturer-set power management settings are very often extremely aggressive in the interests of better performance but don't always take into account the lifespan of the components.
Another number widely quoted in relation to this is 600 000. That is the typical load/unload life cycle of a hard drive. Which means that if your hard disk is anywhere near this you need to consider the fact that it may be nearing the end of its useful life.
