Check the Seagate site here
. They have a utility to set up the drives that should determine whether DDO is required.
There really shouldn't be any problems with that board detecting over 137GB. Have you checked all the BIOS settings to see if there is something there (advanced options can be accessed with CTRL+F1.
Other than that, I'm out of ideas.
