When attempting to encrypt a disk using Symantec Drive Encryption, you receive one of the following error codes:
Could not start disk encryption error: - 11286 (authorization failed)
Unable to start encryption: end of file:-11988 (unknown request)
Check disk space
Check that the free disk space on the boot drive volume (usually C:) contains at least 20% of free space. If not enough free space exists, then it is recommended to clear disk space.
Defragment the disk
If on a Windows PC, run Disk Defragmenter on the boot disk volume using Windows Disk Defragmenter and then re-attempt to encrypt the disk.
Use a new setup file
Download a new setup file of Symantec Encryption Desktop/Symantec Drive Encryption from Symantec Encryption Management Server (previously known as PGP Universal Server).
Use the Secure command
Try the --secure command to encrypt the disk instead of the manual method of adding a user to the disk via pgpwde command line tool.
pgpwde --secure --disk 0 -u testuser -p password --sso --domain TEST
