I am having the problem mentioned in this article but the solution is not working for me since - when I follow all the steps and try to re-partition the external HD - I get the error message:

 

Partition Failed:

 

Particition failed with the error: Could not unmount disk.

 

Trying to reformat a BRAND NEW OWC external HD with 3TB of space, connect via Firewire 800.

 

Help!!
