Original boot sector

The original boot sector is the one that is run after the DEK (Data Encryption Key) has been decrypted and the algorithm and the key have been loaded to the BE filter driver.

If this boot sector is defective, Windows is unable to access the volume. Normally the common error message "Device is not formatted. Would you like to format it now? Yes/No" is displayed.

Nonetheless, SafeGuard Enterprise will load the DEK for this volume. A tool that is used to repair the boot sector needs to be compatible with the SafeGuard Enterprise Upper Volume Filter.
