  The main objective of the paper is to study and develop an efficient method
for Hard Disk Drive(HDD) Security using Full Disk Encryption (FDE) with
Advanced Encryption Standards(AES) for data security specifically for Personal
Computers(PCS) and Laptops . The focus of this work is to authenticate and
protect the content of HDD from illegal use. The paper proposes an adaptive
methods for protecting a HDD based on FDE. The proposed method is labeled as
DiskTrust. FDE encrypts entire content or a single volume on your disk.
DiskTrust implements Symmetric key cryptography with, Advanced Encryption
Standards. Finally, the applicability of these methodologies for HDD security
will be evaluated on a set of data files with different key sizes.
