Second HDD Encryption Issue Mountain Lion

Question

I'm trying to encrypt my second harddrive in Mountail Lion.  When I click on the drive in finder and select encrypt drive, everything goes fine until the drive should start encrypting, then it tells me "A Recovery System for the targeted disk is required."  I have seen support documents that say you should reformat the drive and that will work.  Is there another way to place a recovery partition on my second drive without refomatting?  I've tried to install 10.8 on the second drive, but I get a message that says File Vault 2 will not work since a recovery partition will not be created. 
Any help would be greatly appreciated.

Repair the Hard Drive and Permissions - Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
