SYMPTOMS

You have a computer that is running Windows 7 or Windows Server 2008 R2. When you attach an external Serial Advanced Technology Attachment (eSATA) drive to the computer, the computer recognizes the eSATA drive as a removable disk. However, the computer tags the eSATA drive as a fixed data disk for some other services, such as the BitLocker Drive Encryption service.

For example, you enable a "Deny write access to fixed drives not protected by BitLocker" Group Policy for fixed data drives in Windows 7. When you attach an eSATA drive to the computer, you are prompted to encrypt the eSATA drive with BitLocker if you want to continue using the eSATA drive.

CAUSE

This issue occurs because of an error in Fvevol.sys and Volmgr.sys components. These two components handle external devices.
