As I follow all the articles instructing same, still it is not been clean that if my external drive become fixed then how should is turn back it as removabe. Which is "must" requirement to follow the steps. Other wise i suspect the physical drive option will be disabled.

IS there a limit to the physical disk size that Hyper-V can use in this way? We need a virtual drive larger than 2TB for use in an existing VM guest machine. I can get a 4+TB physical drive showing on the Hyper-V host but I am not sure if it will be seen at 4+TB when I attach it to the VM guest.

The Offline option is not present at all for the removeabel disk in the server manager.

Ben:

First, I thank you. This writeup helped me get physical drives connected.

Second, I am having an issue with physical drives on my VM. I have a Windows Home Server VM on my host and determined that I would want to use physical drives for the data pool due to the drive management scheme that WHSv1 uses. I got the first drive attached to the VM and was able to boot up and add it to the drive pool, but after shutting down to add another drive, the first drive was no longer accessible by the VM. I was able to correct it by removing the drive from the pool and re-adding it, but that solution will not work once data is on the drives, as removing and re-adding will purge whatever data is on the affected drive.

Is there anything you can recommend for this situation?

Hi Ben & thanks for your guides,

I tried to use a phyiscla disk, but instead of using logical partitions hyper-v is using the whole drive.

Do you see another option?

I'd just like to apply the disk as one partition. VMDK files offer exactly this option.

Do you know how to use Add-VMDisk to add the Physical hard disk (pass through) to drive?

"How is with performance physical disk vs. virtual are there any speed boost when using physical drive?"

The physical host doesn't access any files on the same drive so all of the disk arm movements belong to the guest.
