Win8.1 BitLocker on Data Drive

I have a system running Windows 8.1 64bit, and I want to enable BitLocker on my 2TB RAID1 Data Drive  (the Data drive is mirrored through Windows).  When I try to enable BitLocker through the Control Panel, only the Windows Drive (C:\) is listed, not the Data Drive (D:\).

I have attached the disk layout to show the partition layout of all 3 disks
The motherboard does not support TPM, and I only plan on using a PIN for access

Is there any reason why the Data drive is not listed?  Does the OS partition have to by encrypted first?

Hi.

It should be listed. Please try two other ways to start Bitlocker:
->Rightclick d: and select "Turn on bitlocker"
->use the command (from an elevated command prompt)
manage-bde on d: -pw

Open in new window

and quote the output.

Of course the GPO for non-tpm-bitlocking must be set first, see http://www.howtogeek.com/howto/6229/how-to-use-bitlocker-on-drives-without-tpm/

@McKnife: I right-clicked on the D Drive, but there's no option to Turn on Bitlocker.  I tried to run it from the command line, but it said the parameter is incorrect.  I did a manage-bde.exe -?, and saw no -pw option.  I tried running the command without it, but I received the same error.

I discovered that BitLocker will only work on hardware RAID, not a software RAID.  The D drive will only appear in BitLocker once the Windows RAID is removed.

Still, the attachment is missing.
1 apply the policy from my link
2 run the command as suggested, adding -pw:
manage-bde -on d: -pw
[sorry, typing error, forgot the "-" before "on".]
