I had some problems initially on either the Pa600 or Pa900 with some USB sticks ... with the help from KORG USA tech support we narrowed it down to the fact that there were types of files other than KORG files on the stick ... I eliminated the non KORG files and the problem was resolved ...
I don't know if this will help or not ...
