ExpressCache software

Problem 1

IMPORTANT: Although this article specifically cites Lenovo, this issue isn't unique to Lenovo systems. Since the original publishing date of this article, other manufacturers' systems, including Dell laptops, have been reported to also incur this issue.

Lenovo has reported the following issue with the licensed ExpressCache software with the following types of encryption products:

Software - Full Disk Encryption (FDE) products such as DE and EEPC.

NOTE: This also applies to BitLocker, Sophos SafeGuard, and WinMagic SecureDoc.
Hardware - OPAL Self Encrypting Drives (SEDs).

The following symptoms have been reported:

The Express cache might not function.
The computer might perform the same with or without the ExpressCache software installed, therefore losing the expected speed improvements.
The cache might not be encrypted, which defeats the purpose of deploying encryption.
ExpressCache software might cause unwanted side effects in the encryption software, where the system stops responding, or data corruption occurs.

Problem 2

The following specific details have been reported with DE 7.1:

Successfully install DE.
Assign users.
Encrypt the disk and activate.

After restarting the system several times, users who could previously log in at preboot are no longer able to authenticate.

When the preboot system becomes corrupted, you'll see one of the following errors during the preboot authentication stage:

Fatal Error [ee000007] Internal initialization error

Fatal error: File access error at startup

Fatal error: 0xEE0D0001 - Failed to read registry file

MfeEpe.log records the following errors:

ERROR	PcSystem	Error performing policy update: [0xEE0D0001] Failed to read registry file
ERROR	StatusService	Failed to update system policy
WARNING	MfeEpePcEncryptionProviderPlugin	.\..\..\Src\EpeGenSystemPolicyHandler.cpp: EPE_gen_system_policy_handler::set_policy: 353: [0xEE0D0001] Failed to read registry file
ERROR	EpoPlugin	userHandler: failed to process user updates/acknowledgement: [0xEE010002] [0xEE0D0001] Failed to read registry file

Cause

ExpressCache software is incompatible with FDE and OPAL SEDs.

Solution

Uninstall ExpressCache software if your computers have either FDE or OPAL encrypted drives.
