Issue



Symantec Drive Encryption (previously PGP Whole Disk Encryption) is unable to encrypt a drive with a 4k native sector size.


Error



Usually an error isn't included for this problem. But when selecting PGP Disk through the Symantec Encryption Desktop UI the drive will not appear as a drive to encrypt. It may instead generate an unknown error (11980) when trying to encrypt the device as well.


Environment



Symantec Encryption Desktop (previously PGP Desktop) (All versions up to and including Symantec Encryption Desktop 10.3.0)

Hard Drive with 4k Native Sector size


Cause



 This is a known limitation of Symantec Drive Encryption. It does not currently support native 4K sectors. We plan to add support for the 4k Native Sector size in a future release.


Solution



 Drives with native 512-byte sectors are supported.  Many drives with 512-byte sector emulation (commonly referred to as 512e) are supported as well. To determine if your disk drives sector size please see TECH198917
