I'm running Workstation 8 and cannot copy or clone a vm. I have administrative rights to all files and folders. I have tried to copy the .vmdk file to another directory on the same computer no luck. 

Cloning error - Cloning failed : Data error ( cyclic redundancy check)

Copy error screen capture attached - Can't read from the source file or disk. 

I have searched the web and not found anything that helps. I have tried several different external hard drives.

I appreciate any help.
