I have 50gb on an extended Partition that I want to make into a Logical Drive. Problem is that when I right click on it and select New Logical drive I then go through the options and when I get to the part where it will format the partition after I click next I get this

"An unexpected error has occurred. Check the system event log for more information on the error, Close the Disk management, then restart Disk Management or restart the Computer"

The Event Log gives me this

"The parameter is incorrect. (80070057).

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

The link it tells me to go to in the event viewer is also invalid and not much help."

Any Ideas I don't really want to reinstall.
