Using BitLocker on TPM Computers with Multiple Disks

When you enable BitLocker on a TPM computer with multiple disks, the non-boot disks still require unlock passwords or PIN, while the boot disk (C:\) will be unlocked by the TPM chip. In order to automate unlocking of the non-boot disks after login, please do the following:

Use TruGrid dashboard to enable encryption on the TPM computer with multiple disks

Provide the passcode as required

Once encryption begins, login to the computer that you just enabled for BitLocker encryption

Open BitLocker Management Console from Control Panel. Or type this command from command line: control /name Microsoft.BitLockerDriveEncryption

Click on the non-boot disks and use the code typed in step 2 to unlock them

Click on the C:\ (boot disk). Then choose AUTO UNLOCK

Once Auto Unlock is selected, the non-boot disks will automatically be unlocked after authorized user signs on to the computer.
