The hard disk is very hot while in operation

The hard disk is vibrating a great deal while running

The hard disk works but the LED does not light during activity

The hard disk activity LED flickers every few seconds even when nothing is running on the PC and it is completely idle

The hard disk heads can be heard moving occasionally even though the system is idle and the activity LED is off

My hard disk spins down after a period of inactivity even though I disabled power management in the BIOS

I hear a clicking or clunking sound coming from the hard disk occasionally

I hear a loud buzzing sound or rattling sound coming from the drive
