Didn't work. Tried 4 partitions, approx. 20GB each, first one Primary, remaining 3 logical.
Got the following error message:
Error 631 Can't execute the operation: Can't find correct partition

This is what PowerQuest has to say about that error:
Cause: Cause(s) of the problem
Attempted to create a logical partition in a primary free space when an extended partition was already present on the drive.

Solution: Resize the existing extended partition to include the free space where you would like to create the logical partition. (They lost me on that one)


And if the solution doesn't work, per the link above they request 4 different reports/documentation be sent to them.
