I've fully passthrough a 14TB HDD to an ubuntu VM, I log in ubuntu and see in disks the 14TB hdd fine, but when I do any operations like creating a partition then formatting the drive parition in the VM I get errors and unable to continue with this drive.

I look at unraid logs of this specific unassigned disk and it shows the below:

so I've taken the disk out of the VM and ran a badblocks command on it "badblocks -wsv -b 4096 -p 1 /dev/sdh" and there's no errors. I even format and mount the drive in unassigned and can writing to the disk fine.

I've also successfully passthrough 11 other HDDs of varying sizes, same brand "Seagate" to my ubuntu VM without issues.

Any ideas what why this particular disk errors when passed through to a VM?
