Empty drives must be given drive letters or folder mounts prior to being managed by Entrust through the Windows Disk Manager. If no drive letters or folder mounts are associated with the drives, Entrust cannot encrypt them.

For example, if you have a new system with two disks (E: and F:) and a folder mount (C:\data) that has been registered with Cryptographic Security Platform Vault, the hcl status command would return something similar to the following:

C:\> hcl status

We can now add/attach the drives as follows. Please note that this operation is destructive. It will add the drive and format it.

In this example, the E: disk will use the default cipher of AES-XTS-512 and the folder mount C:\data disk will use AES-256. For details on the encryption ciphers, see Encryption Key Sizes and Algorithms.
