    If it is required in an environment where USB drives are allow to be used with servers this will help you of getting access to external storage from within a vm. It’s a very useful way of seeding initial copies of backup data.

    1. Attach the USB drive to the Hyper-V host server.

    2. Right click the USB disk (in our case Disk 1) and select Offline.

    3. Disk 1 is now offline.

    4. Select the vm Settings of the vm that you want to Add the USB drive to and select the SCSI Controller, highlight Hard Drive and click Add.

    5. Select Physical hard disk, using the pull down menu you should see the offiline disk on the host available to you, select it and click Apply, click OK.

    6. Within the vm start Server Manager, select the Tools menu, and select Computer Management, expand Disk Management, and you should the USB disk is offline. Right click Disk 2, and select Online.

    7. You can now see the disk in File Explorer on the VM and can copy data to and from it.

    To dismount the disk perform the following steps.

    1. In the VM go to Disk Management, and select Disk 2 (in this example) and set to Offline.

    2. In the Settings of the VM, expand SCSI Controller, and select the Hard Drive that you have used to mount the USB disk. Click Remove, Apply, OK.

    3. Right Click the USB icon in the System Tray and select Eject.

    Hope this will help you to perform external disk with Hyper-V.

  • FYI - not all USB disks can be simply attached as a Passthrough disk

    the driver for the USB disk must expose the disk as a 'disk drive' to the operating system and not a 'removable disk'.

    That is the key.

    If you USB disk is USB 3 and you have a USB 3 hub on your PC, you can use Direct Device Assignment to attach the USB HUB to the VM, then the disk will be like any removable disk.
