Did you, by any change, create a VM with a floppy drive, installed Windows and then one day removed the floppy drive from the VM?

In that case disable the floppy drive in the Device Manager of Windows and see if the error goes away.



  1. Launch Control Panel \ Device Manager
  2. Select Floppy disk drives \ Floppy disk drive
    • Right click on your selection
    • From the drop-down menu, please select disable
 Device Manager – Original

VMWare – WorkStation (v8) – Expanding Disk – Error – The called function cannot be performed on partial chains. Open the parent virtual disk (0x500003e83)


I am just getting over a mishap I had with VMWare WorkStation Version 8.
On the VM Guest, the original provisioned disk was 40 GB on drive C: and 60 GB on drive D:

Not enough to do much with these days, and so I set out to increase it.


Attempt Disk Increase Using GUI

I took the VM Guest offline and tried increasing its disk layout.  But, each time on both disks (Disk C: and Disk D:)  got the same error message:

The called function cannot be performed on partial chains. Open the parent virtual disk (0x500003e83)




Attempt Disk Increase Using Command Line (vmware-vdiskmanager.exe)

Using VMWare’s vmware-vdiskmanager.exe:


cd C:\Program Files (x86)\VMware\VMware Workstation
vmware-vdiskmanager.exe" -x [new-size] [file-name-vmdk]


cd C:\Program Files (x86)\VMware\VMware Workstation
vmware-vdiskmanager.exe" -x 75GB Data-000003.vmdk

But, getting the same error…

Goggled for Help

I have one thing going, and that is an Internet connection — “Country Boy will survive

Here are the steps prescribed.

Clone VMWare Disk

Let us clone the disk; that is create a copy of the disk.

Again, keep in mind that you need sufficient disk to make a copy of the existing one. So you need about 1.5 * allocated VM disk space.


"C:\Program Files (x86)\VMware\VMware Workstation\vmware-vdiskmanager.exe" -r virtual-machine-disk-source -t 0 virtual-machine-disk-destination



"C:\Program Files (x86)\VMware\VMware Workstation\vmware-vdiskmanager.exe" -r Data-000003.vmdk -t 0 Data-000003-Clone-20131105.vmdk





Creating disk 'Data-000003-Clone-20131105.vmdk'
Convert: 100% done.
Virtual disk conversion successful.


Expand Resultant VMWare Disk

Let us expand the disk image that resulted from our cloning exercise.


C:\Program Files (x86)\VMware\VMware Workstation\vmware-vdiskmanager.exe" -x [new-size] [cloned-disk-file-name]



C:\Program Files (x86)\VMware\VMware Workstation\vmware-vdiskmanager.exe" -x 75GB Data-000003-Clone-20131105.vmdk
