description To comply with a policy for a computing device indicating that data written by the computing device to the storage volume after activation of the policy be encrypted, a sector map is accessed. The sector map identifies one or more sectors of a storage volume and also identifies, for each of the one or more sectors of the storage volume, a signature of the content of the sector. In response to a request to read the content of a sector, the content of the sector is returned without decrypting the content if the sector is one of the one or more sectors and the signature of the content of the sector matches the signature of the sector identified in the sector map. Otherwise, the content of the sector is decrypted and the decrypted content is returned.
