Drive Encryption

Hi,

We are testing the Device Encryption in our network, we are facing some issue

we are enabling the device encryption in a system and after encryption, we remove the HDD from this system connect to another computer to check it works or not

that time we are entering the recovery key which is available by Sophos central but this key is showing this key is incorrect.

anyone have the idea of unlock the drive

Thanks
