Patent ID: 8312296

Claim:
An information handling system, comprising: a processor; a memory communicatively coupled to the processor; at least one storage resource communicatively coupled to the processor; and one or more computer-readable media communicatively coupled to the processor and having one or more instructions stored thereon, the one or more instructions configured to, when executed by the processor: periodically store, during an encryption or decryption operation performed on a volume of the at least one storage resource, one or more variables indicative of an encryption status of the volume in a master boot record signature of the volume; read the master boot record signature of the volume; determine, based on whether a specific value exists in the master boot record signature, the specific value indicative of whether the volume is in a partially encrypted or decrypted state; and in response to a determination that the specific value does not exist: decrypt the master boot record signature; determine if the specific value exists in the decrypted master boot record signature; and if the specific value exists in the decrypted master boot record signature: read a variable from the decrypted master boot record signature, the variable indicative of a portion of the volume that has been encrypted or decrypted; and boot from the volume and continue the encryption or decryption operation based on the variable indicative of a portion of the volume that has been encrypted or decrypted.
