No. I Have: (viewing the last picture : On Device Manager)Why don´t you try has only one partition on each usb pen drive, i.e:
1) - one -> mapped as /media/usb
on /media/usb --> used for Open Multiboot; picons ...
2) - other -> mapped as /media/hdd
on /media/hdd --> for xbmc; movies... for recording you must create in it the folder <movie>.
Note: Reserve for this the bigger one USB pen Drive.
This probably will avoid confusing the medias.
