Hi All,

I am again in trouble, Actualy we brought a Lenovo Think center model M92 P desktop. We have installed Windows 7 Ent SP1 on it and when we are trying to encrypt it we are getting error "unable to encrypt Bad perameter -12000". The PGP IS is a managed client with PGP Universal Server 3.2.0.

I also serach some article over internet and found to disable UEFI mode in BIOS. and i dis that i Disable the UEFI mode and enable the Legacy Mode then i Reinstall the OS and rebuild all the partition. but still the error is same "Unable to Encrypt HDD bad perameter -12000" can anyone help me in this regard.
