vmware converter: Unable to clone volume 'C:'

When I used Vmware vCenter Converter Standalone 3.0.5 to dynamically converter a physical machine (Windows 2003) to VMware virtual machine.

Get error when just finish 1%:

vmware converter: Unable to clone volume 'C:'.

for vmware converter log:

Google about “Found dangling SSL error: [0] error:00000001:lib(0):func(0):reason(1)”, get a useful info:

get this error is caused by VSS, not converter, or something relate to SSL.

check source machine’s event viewer: VSS error:

check the GUI {24602736-bed9-4619-91b0-243447c6409c} from regedit:
got the VSS provider:

StorageCraft Volume Snapshot Software Provider

This is our backup software. Looks VMware is not compatible with StorageCraft’s backup software.

Uninstall it, conversion finished successfully.


  1. Yep... this appears to be the solution for me too. The error was "converter.fault.CloneFault". Removing StorageCraft allowed the conversion to proceed normally (albeit slowly).


  2. This has worked for me under VMware Converter Stand Alone v6. Sad that VMware themselves don't seem to have an article that describes this issue, it's taken my quite some time to find this solution - thank you!

  3. Spoke too soon, damnit. Conversions were failing as soon as the job started previously, this time it took some time before it failed.

    I saw there's a timeout setting in the worker XML config file, I might play with that.
