WD30EFRX - only 746 Gb of 3 Tb is visible and avaliable?

The disc was instaled on NAS and removed unsafe. After that I couldn’t use this. Avaliable pariton was formatted NTFS by NAS. The rest should be EXT4. Please advise how to restore full volume? Data restoration is not important.
I’m in Papua New Guinea now and can’t get any support( Please help! See screenshot.

Hi Dimitri8,

First, run Extended Test using Data Lifeguard Diagnostic Tool in order to check the health of the drive. If passes, try to reformat the drive in GPT file partition type.

Hi, Thanks for the answer. I did as adviced but result is the same…
