There are a few conditions that have been reported concerning an encryption or decryption process that has gone into a "paused" state:
• The encryption or decryption process may pause after a system wakes up from Sleep or Standby Mode.
• The encryption or decryption process may state "paused" in the PGP Whole Disk Encryption User Interface, but is actually encrypting in the background.
• Certain systems randomly going into a "paused" state during encryption\decryption process.
Systems not resuming the encryption\decryption process after waking from Sleep or Standby Mode was a known issue (2753309) that is resolved in Symantec Drive Encryption 10.3 and above.
Check to see if the machine was recently resumed out of Sleep or Standby Mode and if it was, click resume, or via the command line, run the following:
c:\program files[x86]\PGP Corporation\PGP Desktop>pgpwde --resume --disk 0 --interactive
Enter the passphrase to authenticate the disk and encryption/decryption process should resume.
If the System has paused on its own and did not recently wake from Sleep Mode or Standby, this is another issue that is resolved in 10.2.1 MP5 by allowing the user to click "resume" to continue the encryption/decryption process.
If the PGP Whole Disk Encryption client states "paused", and it is not expected, check the status of the encryption via the PGP Command Line:
c:\program files[x86]\PGP Corporation\PGP Desktop>pgpwde --status --disk 0
Run the status command a few times and if the total sectors for the watermark does not change, then the disk is most likely paused.
If the encryption\decryption process is truly paused, attempt to resume the encryption process via the PGP Whole Disk Encryption UI, or via the command line.
