Is this reserved partition related to Veem? If not then it seems there was an OS on the disk previously. The 128MB partition is the MSR but that is usually created when installing an OS. Run the diskpart list disk command again and see if you get the full size. Select disk X Where X is the number of your 4TB internal driveĬlean This wipes the partition table so make sure you have the correct disk in the previous step I would do the following but you would need to back up the data on the disk first.
