Creating, Using, and Transferring Files Using Virtual Floppy Disks

Creating, Using, and Transferring Files Using Virtual Floppy Disks

Applies to: Hyper-V and Hyper-V Manager enabled devices
May also be known as the virtual floppy shuffle

Before you can use a floppy disk in Hyper-V, you will have to create it in Hyper-V Manager.

1. Right-click the Hyper-V server where you want to create the floppy disk, click New, and then click Floppy Disk.

2. Select a physical file and folder location for the virtual floppy. In the File name box, enter an appropriate name, which is cafloppy.vfd in this example, and then click Create.
3. Once the floppy is created, you will have to mount it into a virtual machine that you want to make use of the floppy disk.

4. Use the Hyper-V virtual machine toolbar for the virtual machine to mount the floppy. The first time you mount the floppy, you will be asked for format it. Click Start, click Run, then type A: and press ENTER.
5. A dialog box appears to inform you that the floppy needs to be formatted. You can use Quick Format and then walk through the rest of the options.

6. Copy the required files from the source virtual machine to the virtual floppy.

7. Once the files are copied, unmount the floppy disk from the source computer, by configuring the virtual machine settings for the floppy disk to None.

8. Mount the floppy disk on the target virtual machine.

9. Open the A: drive on the destination virtual machine to access the files that you wanted to transfer.

  • It would be great to see the PowerShell cmdlets needed to do all the above.

    The basics are:

    New-VFD -p C:\vms\foo.vfd

    Set-VMFloppyDiskDrive -Path F:\vhd\dc1.vfd -VMName 'Foo'

    What I don't yet know how to do is to format the floppy and to copy files to it from a host.

  • Thanks for sharing. We can also leveraging SCSI controller which supports Hot Plug. It's documented here.

    Hyper-V: Configure a virtual machine with a SCSI controller to be able to hot plug and hot unplug storage

    Thus we can create a vhd/vhdx file, mount it and copy more files. :)

    With Hyper-V 3.0, these steps can be fully automated.
