If you've recently made any hardware modifications to the box, especially adding extra new bits, then that's a distinct possibility. However, much more likely is that your hard drive is developing a fault. Moving parts wear out, and hard drives can be quite fragile, especially if they have been used heavily or are running at high temperature. (If you've maxed out an ordinary tower case with hard drives, then you really should think about adding extra fans to improve the air flow. Server class or rack mount kit is usually designed to cope with the extra drives already.) First of all, make sure you have good backups. That disk could give up the ghost at any moment. Make sure the machine is adequately ventilated, that all the fans are working and that any vents are not clogged with dust. If that doesn't make things any better, it's time to get out the screwdrivers and start swapping out the suspect components.
