1. Does the 'New' directory exist on the D: drive? (I am guessing that it is a new, freshly formatted spindle drive)
2. if New and Stored are on the same drive, there is no benefit (and some performance hits) to using both of them. Set your system to save the files to New. Turn off limit clip age and set the retention to the max using limit size (if the drive is not used for anything else, use the total drive storage amount minus about 10%).
