Products

• Symantec Products

Issue/Introduction

If the disk is already instrumented, i.e. due to a previously failed encryption attempt, the encryption will fail with an error.

If the internal user policy required automatic disk encryption the initial enrollment will fail.

An Error Occurred - PGPError #-12291

Cause

PGP Whole Disk Encryption will fail if the disk is already instrumented.

Resolution

To resolve this issue uninstrument the disk using one of the following:

 

1. Uninstrument via pgpwde commandline using the command: 

         pgpwde --uninstrument --disk <number>

                    Where  --disk specifies the disk number to be uninstrumented 

 

2. Uninstrument by starting PGP Whole Disk Encryption, then select Pause and choose to decrypt the disk.

 

Applies To

PGP  Desktop 10.2 (as well as all PGP Desktop 10.x versions)
