SEE Removable Storage conflict with TrueCrypt

Created: 19 Dec 2012 • Updated: 04 Jan 2013 | 3 comments
This issue has been solved. See solution.

We have just deployed our SEE Removable Storage and Device control to all users and at the same time we upgraded our SEP clients to 12.1.2.  We have some people on our networks/security team that uses TrueCrypt to mount volumes on their computers for encryption so that they can send this information to other people/agencies.  The problem is that TrueCrypt will mount the volume that you choose but when you open Windows explorer you cannot open the new drive that TrueCrypt creates.  It gives the error Access Denied.  The only way to get it to work is to dismount and remount the volume, and I am not sure what difference that makes.  I have tested this to see which application is causing it and I still have Device Control and SEP installed on the computer and TrueCrypt works like it should.  If I install Removable Storage then it breaks.  What on earth could cause this?  

Our environment:  Windows 7 Enterprise 64 bit

SEE 64 bit clients

SEP 64 bit cilents

It could be that SEE is thinking that its a removable disk.  Did you have any other installations of SEE prior to this one without incident?

Please mark posts as solutions if they solve your problem!

Not sure that it sees it as a removable disk.  The volume shows up as a local disk in Windows explorer.  That is the only installation of SEE, this is our first time using it.

Turns out this is a simple case of "do not use 2 different encryption applications".  We are going to phase out TrueCrypt and tell those 5-8 users who use it to go to SEE-RS for encryption from now on.  Thanks for all the help.  

The two applications are simply trying to access the same resources and since Symantec is the only one of the two that offer support, that is the one that we will use.
