Mountain Lion allows one to encrypt any disk by right-clicking on the disk in the Finder and selecting Encrypt from the contextual menu.

Is there anyway to check on the progress of this encryption process?

Open up the Terminal and enter the command:

diskutil cs list

You will see an output listing at least one Logical Volume Group, with a Logical Volume Family and Logical Volume nested below.

There is be a Conversion Status item in the Volume Family entry that will tell you if it's converting to an encrypted volume or not, and for a progress indicator, look under the Logical Volume entry for Size (Total) and Size (Converted) entries, to see how many GB have been converted so far.

During encryption:

Encryption Status:           Unlocked
    Encryption Type:         AES-XTS
    Conversion Status:       Converting
    Conversion Direction:    forward
    Has Encrypted Extents:   Yes
    Fully Secure:            No
    Passphrase Required:     Yes
 Disk:                       disk6
    Status:                  Online
    Size (Total):            569869340672 B (569.9 GB)
    Size (Converted):        231454277632 B (231.5 GB)
    Revertible:              Yes (unlock and decryption required)
    LV Name:                 Heap
    Volume Name:             Heap
    Content Hint:            Apple_HFS

Encryption completed:

Encryption Status:           Unlocked
    Encryption Type:         AES-XTS
    Conversion Status:       Complete
    Conversion Direction:    -none-
    Has Encrypted Extents:   Yes
    Fully Secure:            Yes
    Passphrase Required:     Yes
 Disk:                       disk6
    Status:                  Online
    Size (Total):            569869340672 B (569.9 GB)
    Size (Converted):        -none-
    Revertible:              Yes (unlock and decryption required)
    LV Name:                 Heap
    Volume Name:             Heap
    Content Hint:            Apple_HFS

The actual Terminal output is nested and longer. Here, only the most important information is listed.

Would you know if it's expected that erasing a disk (formatting) with enabling encryption, and then copying 50GB of files to that shows the "Complete" state immediately when copying is done? But when doing the same for Time Machine (first erasing and enabling encryption), TM goes into (another?) long lasting encryption process when the first backup is complete? Both start with an empty, encrypted disk... –  Arjan Mar 14 '13 at 9:19
