Bitlocker does not want to encrypt disk | K2000

Hi, everyone,

I've been using the KACE SDA k2000 for a long time now, but since the new KBE update, the Bitlocker don't  worked recently.

When trying to activate the bitlocker I keep getting this error message:

"The new active drive cannot be formatted. You may need to manually prepare your drive for Bitlocker."

After a long research I found out that the disk is not properly partitioned. I have already tried some pre-installation tasks, but without success. I keep getting this error message.
