Hard Drive Myths part 1

August 10th, 2009

One sign of the hard disk’s calibration process is the spin-up and spin –down events. The hard disk recalibrates itself to balance the changes in temperature which is also adjusting the position of data on the platter surface and when the hard disk can not scan the data properly. As a result, if the hard disk recalibrates a lot it might be a symptom of a failing hard disk.

However, take note that there is hard disk that programmed to saves power. In order to saves power the hard disk spin down and when there’s work to be done that’s the time to spin-up again.
