What is new?

  • User password authentication type;

Works Swell

BUT one small thing…

once the user tries to encrypt the "x:" drive and at the last minute decides to cancel…
BSOD Appears…


Excellent :■■■■ :BNC :■■■■ :BNC :■■■■ :BNC :■■■■

Please follow the guide on how to upgrade!

I did,

I’m trying this on a virtual machine…
and this is how you can reproduce the problem

Start up CDE > Right click C:\ > Encrypt > Enter the desired info… > at the last window click the red X button and BSOD Will appear



Voila, the long awaited one ;D. Great job development team :■■■■


Stay assured we will verify this, but please post it on BUG section.

My expiriences…
Very slow shutdown after install.
Run as Administrator is not preset on the Vista Shortcut.

For the rest great work on this new release :BNC

Great job guys!!!

I tried it but it didn’t happen.

Great piece of work! (R)

Thanks Team!! Great job!

Can you reproduce this again?
please attach the memory dump file…

Hi Guys,

I created a new Bug Report Thread here:


It doesn’t happen again i don’t know why…
No i don’t have a dump file…


Maybe someone could answer a few questions about CDE Beta:

  1. I have encrypted my primary patrition with password protection. After encryption the machine’s boot time increased, and the Operating System is loading slower . Is this normal?

  2. If I’ll decide to encrypt the second, logical partition, it will use the same password at boot time as the primary partition, wich is encrypted already? Or, to be more exact, can I encrypt two partitions and use the same password, even if the encryption protocols are different (like on C:\ I use SHA256 with AES, and on D:\ I’ll use MD5 and Serpent)

  1. It is normal that the machine’s boot time increased, depending on the encryption algorithm you chosed.

  2. If you decide to encrypt a second partition it will use the same password. You cannot encrypt on a computer, 2 partitions with two distinct passwords or authentication types. But you can change hash and encryption algorithms.

Just a minor detail:

The installer defaults to:
c:\program files\comodo\Comodo Disk Encryption - BETA

All other Comodo products install like this:
c:\program files\comodo\Disk Encryption
