I have tried to 'cd' into /fs/etfs and received message 'device busy'.  I get same message trying to perform other tasks
 on it.

Normally I would try to mount /dev/etfs2 as the partition I want to a mount point.  But even doing this fails giving;

mount: Can't mount /mnt/usb (type qnx4) 
mount: Possible reason: No such device or address 

Do I need to format it?

Do I specify the size of etfs1 (raw partition) to include the 0-100 blocks I need reserved?
