omni 27 3tb externel HD

Omni 27 1001ed
Microsoft Windows 10 (64-bit)

I have an All in one desktop Omni 27 1001ed. Now I want to use my external HD 3TB but it only reconize 2TB. Can someone explain what to do to get the other 1TB also.


I have already changed the disk to GPT and formatted it again. Still no result.

Welcome to the HP Forums :)

I would like to take a moment and thank you for using this forum, it is a great place to find answers.


As I understand you've connected 3TB drive but only 2TB is showing up,

The new partition displays in the Disk Management utility as Unallocated space, follow this link for more details on how to allocate the hidden 1TB storage: Click here


If I have helped you resolve the issue, feel free to give me a virtual high-five by clicking the 'Thumbs Up' icon below,
