Hi,
Do you mean you would like to use the "ST2000DM001-1ER164 HDD 2000398934016" disk to create a storage pool, however, there's a partition on it and it shows "Insufficient Capacity".
Does the disk show as Games (G:) or the Unallocated partition? Please highlight it in the disk manager.
Besides, please also show the screenshot like below:
Besides, please try to use the powershell command "Clear-disk" to remove the partition, check if there's any error, if yes, please provide the error message:

Thanks for your time!
Best Regards,
