3TB HDD showing only 746 GB Unallocated in Windows 11

Regular Visitor

I have HP Pavilion ec2275ng laptop. When I connect 3TB HDD via USB , I don't see it in explorer. In Disk Manager it says unallocated and shows only 746GB. Disk is already GPT partitioned.

When I connect this disk to three different computers with Windows 10 installed, everything works OK.

I don't know what to do, because I can't format this disk. It has over 1,5TB of backup data on it.

 

Edited later:

I downgraded this computer to Windows 10 and it recognised 3TB disk with no problems. Aparently it is Windows 11 fault.
