METHOD FOR GENERATING PHYSICAL IDENTIFIER IN STORAGE DEVICE AND MACHINE-READABLE STORAGE MEDIUM
First Claim
1. A method for generating a physical identifier in a storage device that includes a plurality of storage regions, the method comprising:
- determining a number of reference storage regions for uniquely identifying the storage device;
comparing the number of reference storage regions to a threshold;
generating auxiliary storage regions for uniquely identifying the storage device, such that a number of the auxiliary storage regions corresponds to a result of the comparison;
generating location distribution information of the reference storage regions and auxiliary storage regions; and
storing the location distribution information in the storage device.
