When attempting to encrypt a disk with Symantec Drive Encryption 10.3.0 or previous (formerly known as PGP Whole Disk Encryption) the operation fails and you receive the error below.
Error code: 12000: bad parameters
Symantec Drive Encryption 10.3.0 and previous did not support computers using UEFI firmware and would run into this issue, therefore, this issue could occur if computers are running UEFI firmware without emulated BIOS.
Symantec Drive Encryption 10.3.1 includes UEFI support for Windows 8, but not Windows 7.
Symantec Encryption Desktop 10.3.2 has support for UEFI for Windows 7 64-bit and Windows 8.0/8.1.
Symantec Drive Encryption 10.3.2 and above now supports GUID Partition Table (GPT) formatting on Microsoft Windows 7 64-bit systems and Windows 8.0/8.1 64-bit systems, running in UEFI mode.
Systems using UEFI should upgrade to Symantec Drive Encryption 10.3.2 or above to obtain this full support for this new functionality.
Refer to article TECH203071 for more details on UEFI support and Symantec Drive Encryption.
UEFI and BIOS are different types of firmware being used by computers. There are three types of bootstrap configuration on laptops and workstation computers:
UEFI > Operating System Boot loader
BIOS > Operating System Boot loader
UEFI > BIOS (emulated BIOS) > Operating System Boot loader
Symantec Encryption Desktop 10.3.0 and previous support
UEFI emulated BIOS boot configuration.
If an operating system is bootstrapped from UEFI directly, a newer version of Symantec Drive Encryption is required.
