I trying to use the new BD partition manager in RTEMS. I am using a compact flash card in my system as the removable storage device. I registered and mounted the compact flash card and I was able to see all of the directories and files. I then unmounted and unregistered the partition. I removed the compact flash from the system and added a directory using windows XP. I then reinserted the card into the system. After registering and mounting the partition, the new directory does not show up. As a side experiment, I unmounted/unregistered the partition, removed the compact flash from the system, and re-mounted/registered the partition (without the compact flash present). It successfully mounted. I assume that the MBR sectors are being cached as part of the BDBUF manager. When a partition is unregistered, should the BDBUF cache be cleared so that the next register forces a read from the disk itself?
