Converter 5.5.3, ESXI 6.0, P2V. "An error occurred during the conversion: 'converter.fault.FileIOFault'"

Converter 5.5.3, ESXI 6.0, P2V.  "An error occurred during the conversion: 'converter.fault.FileIOFault'"

The Job failed at 35%.  When I looked up the error it says that a HD error occurred and that I need to do a defrag.  Before I do this I want to check and make sure that 5.5.3 converter is compatible with ESXi 6.  I can't seem to find anything on this.

This is my environment:

Physical Box: IBM, Intel Dual 8c processors, 16 GB Ram, Raid 10

Virtual environment: (host)Dell r620, Intel Dual 8c processors, 64 GB Ram.  (san) Equallogic 6100, Raid 10

Thanks all, I just dont want to waste my time doing a defrag if the converter is not compatible.
