Issue/Introduction

Symantec Encryption Desktop shows the disk as a "Removable Drive" not as a "Fixed Disk", on Dell Latitude E7240 and E7440 Ultrabooks:

Internal drive showing as removable

While you actually can encrypt the disk by adding a normal passphrase user, you may be unable to use the following features:

  • SSO feature
  • Display detailed authentication fields
  • WDE Admin passphrase user

 In addition, the bootable SSD drive on the Latitude E7240/E7440 may show as a removable device in Windows, with the option to "Eject Media". 

Cause

 The SATA RAID driver causes the disk to incorrectly appear to be a removable drive and not a fixed drive. The above mentioned affected features are not supported on removable drives.

Resolution

Dell have published the following knowledge base article about this issue. Follow the steps in the article to stop the SSD boot drive appearing as removable media:

SLN293012 - The SSD boot drive appearing as removable media on the Latitude E7240/E7440 

Alternatively, carry out the following steps:

1. Check the version of your Intel® Rapid Storage Technology (Intel® RST) RAID Driver. If you are not running version 12.9.0.1001, you can update through the following link:

 Intel® Rapid Storage Technology (Intel® RST) RAID Driver 12.9.0.1001

Note: Currently the 12.9.0.1001 RST driver is the only one that seems to resolve the issue. The newer release of the RST driver (13.1.0.1058 on 5/27/2014) may not resolve the problem.

2. After you have updated the driver, reboot the PC. The disk status of affected machine should have changed to "Fixed Disk". 

 

If updating the Rapid Storage Control driver does not resolve the issue and you are using a managed client, please check the user's policy.
