First, I would recommend upgrading ePO and Drive Encryption. The EEPC 7.0.3 Extension, the "plugin" within ePO used enable the functionality to manage the point product (EEPC) on the cleint system, is no longer supported. The EEPC 7.0 extension was only supported on ePO 4.6 and 5.0. Both of those versions of ePO are end of life / end of support as of December 2015. EEPC 7.0.3 was released January 2014. To upgrade ePO and the EEPC extension, please follow KB81538.
There is several KBs that cover this issue:
Some notes about OPAL with Drive Encryption.
- The systems SATA Operational Mode must be set to AHCI (KB81136). This also applies to all SSD drives.
- If the system is in UEFI mode, it must be Windows 8 or above certified by Microsoft (KB81136)
- If the system is in UEFI mode, the OPAL drive must be shipped in the system from the OEM (KB81136)
- The drive must be a supported OPAL drive and listed in KB81136.
- The correct storage driver must be installed. Typically this is the Intel Rapid Storage Technology (IRST) driver.
If the system does not meet these requirements, the system can still be encrypted with the software encryption provider. To encrypt with software provider, edit the Product Settings policy, click the Encryption tab, and move "PC Software" to the top of the list by clicking "Move to top".
To deactivate the system, you will need to use the DEOpalTech disk. First you must determine if this is a UEFI or Legacy BIOS system. Go to ePO and navigate to the system in the System Tree and click on the system. Select the Drive Encryption tab and select "More". You will see "Firmware Type" and next to it will show either EFI or BIOS. Based on this, follow PD24871 to build a DEOpalTech disk or use the EZPE tool to build the correct disk. Once the disk is created, you will need to authorize using the code of the day and deactivate by clicking the Remove EE.
Thank you this helped me solve it
