The hard disk is very hot while in operation

Explanation: The hard disk feels very hot while it is operating.

Diagnosis: It is normal for hard disks, especially newer ones, to feel hot while they are operating. They should not get as hot as solid-state components like processors; they will often feel warm to the touch but should not be uncomfortable to put a hand onto. Newer disks that spin at 7200 RPM or higher will tend to get hotter than older, slower drives. A properly-ventilated case should be able to handle all but the hottest drives without additional cooling measures being required.

Recommendation:

Check the cooling level of the case as a whole if you suspect that the case is not being ventilated properly.
You may want to change the physical layout of the inside of the case. If the hard disk is mounted close to another disk or other hot-running components, or in a place where it will not receive much air flow to cool it, moving it may reduce its temperature.
High-performance disks such as Seagate's 10,000 RPM Cheetah often require special cooling arrangements. I recommend you contact the manufacturer directly for advice on cooling high-end, high-RPM disk drives.
