Abstract:
For generating a random number in a disk drive, a seed is generated from a respective sector number for each of at least one sector of the disk drive. The random number is calculated using the seed. The seed that is generated with enhanced unpredictability and complexity is used to generate the random number for secure data cryptography within the disk drive.
