I'm trying my first BitTorrent download from the PBO with a 80GB USB HD. There is a strange issue here:

1. I was able to see the C: drive in the torrent upload page, and load the torrent. But the torrent doesn't appear in the torrent list after I click "Yes" to confirm the upload. But I was able to see the torrent name and folder under C:\BT\ in the USB drive through Windows Explorer.

2. So I try to upload another torrent file. This time I am not able to see the drive letter from the upload page at all. The dropdown list is empty. But I am still able to see that USB drive attached to PBO from windows explorer, and able to copy files to and from it.

What is going on with the BT app on the PBO? Does it have to be an internal drive instead of a USB drive?
