This is what pgpwde --status should look like if it's fully encrypted:
"c:\Program Files (x86)\PGP Corporation\PGP Desktop\pgpwde.
exe" --status --disk 0
Disk 0 is instrumented by bootguard.
Current key is valid.
Whole disk encrypted
Total sectors: 250069680 highwatermark: 250069618 reserved start sectors: 62
Failed login attempt lockout enabled. Max failures=5
Request sent to Disk status was successful
The "watermark" that weevil describes is the total sectors vs highwatermark. You should always have total sectors - start sectors for your high watermark if it's complete. If highwtaermark is at a much lower number, encryption is still in progress. The watermark is a number that is incrimentally updated based on the encryption progress.
BTW:
Many issues with encryption pausing or not completing can be resolved by following our WDE best practices KBA here:
