ExpressCache software is incompatible with disk encryption.
Symptom

ExpressCache and disk encryption are incompatible.  This is true for all types of encryption: both hardware (e.g. OPAL and FDE) and software (e.g. BitLocker, Sophos SafeGuard, WinMagic SecureDoc, etc).  One or more of the following symptoms may be observed:

  1. The cache may not work at all.  The system may perform the same with or without the ExpressCache software installed.
  2. The cache may not be encrypted.  This defeats the purpose of deploying encryption.
  3. The ExpressCache software may cause unwanted side-effects in the encryption software, such as lock-outs or data corruption.

 

Affected configurations


The above symptom is associated with, but not limited to, the following ThinkPad systems:

  • All ThinkPad

The system is configured with:

  • mSATA or M.2 SSD and ExpressCache software

Applies to:

  • Microsoft Windows 7
  • Microsoft Windows 8

 

Solution


None.

 

Workaround
