Recover disk original capacity

We installed the 3TB WD30EZRX-00MMMB0 in a silverstore nas 2 NAS , which I assume initialized it with a proprietary format.

Then we had to remove it from the nas and wished to use directly on a windows computer .

However the disk is recognized as 748GB in size .

We tried with diskpart but it reports it as 748 GB disk no matter the command we tried ( clean , etc )

Is there a wdc utility to recover the disk to its original state and get it seen as 3 TB disk ?


What operating system?
