Encryption is not activated

Question

Hi everyone 
 Thanks for the help you are giving 
 I do not activate the encryption on the second partition of a single disk of a PC 
 Dell Precision T3600 Windows 10 build 1909 (10.0.18363) bios Version A18 Sophos Safeguard 8.20.0.83 TPM version 1.2 
 The policy is working regularly on all other PCs. The problem occurs only with this model and i can't find the difference with other pc. 
 Any idea 
 Thanks in advance 
 Regards 
 Franco

what do you have for your encryption targets in your SGN policies. I would assume you only have boot drives targeted so only C will be encrypted. 
 You would need to create a policy that targets data drives or a specific drive letter to encrypt anything that isn't the boot drive.

I don't think the version of the TPM is at issue here. If it was, the main boot drive wouldn't encrypt - but you have that working. 
 If the issue is just that data drives don't encrypt but boot drives do - you need to make sure you have an encryption policy assigned that targets data drives not boot drives. You need both policies to encrypt both drives. Can you post your RSOP for the machine here please.
