Problem adding physical SATA disk as RDM in ESXi 6.7

I followed the instructions in this guide to add the disk to my Windows 2016 server guest VM.

How to passthrough SATA drives directly on VMWare ESXI 6.5 as RDMs · GitHub

So, the drive appears and it recognizes the size in Windows. However, the problem is that it shows as a RAW partition in Windows although the drive has data in it. I don't recall if it is formatted as NTFS or exFAT, but the partition scheme is GPT. The drive is 4TB and has a single partition.

Any ideas?

Have you tried to run checkdisk ?
chkdsk /f /x /r /v F:

I don't think we can do scan disk on RAW disk.

I have same issue with 4TB GPT disk, but not on my 2TB MBR disk. I attach both disk to the same VM. Looks like this issue related to disk layout (GPT/MBR).

Finally, I can access my 4TB RDM disk. I've just attached it on SATA (virtual) controller on the VM.

And, I have access to my 4TB (GPT) RDM disk.
