Abstract

A mechanical transport device includes a system for transport; and a hard disk drive attached to the system. The hard disk drive comprises a magnetic recording disk to record data, a head to read or write the data to or from the disk, and a drop sensor designed to sense a shock condition. The system for transport may be a vehicle such as a car.

Claims

1. A mechanical transport device comprising:

a system for transport; and

a hard disk drive attached to said system, wherein the hard disk drive comprises;

a magnetic recording disk to record data;

a head to read or write the data to or from the disk; and

a drop sensor designed to sense a shock condition.

2. The mechanical transport device of claim 1, wherein the system for transport is a vehicle.

3. The mechanical transport device of claim 2, wherein the vehicle is a car.

4. The mechanical transport device of claim 2, wherein sensing of the shock condition by the drop sensor is changed adaptively.

5. The mechanical transport device of claim 1, wherein sensing of the shock condition by the drop sensor is changed adaptively.
