Abstract
A method to prevent data loss includes monitoring a vibration from a computer rack and, when the vibration is harmful to a hard disk drive in the computer rack, moving data in transition to the hard disk drive to another hard disk drive, spinning down the hard disk drive, and sending an alarm. The method further includes, after the vibration is no longer harmful to the hard disk drive, spinning up the hard disk drive, moving the data from the other hard disk drive to the hard disk drive, and clearing the alarm and adding an event to an alarm history.
