在网站看到DM800使用OE1.6版本的下面说明： 
 
“* USB-Stick 
New kernel has changed usb identification. If you plugin an usb-stick, it is identified as sda1. After rebooting your box, it will be identified as /media/hdd. 
The reason is very simple: sda1 can be an usb-stick or an external hdd” 
 
大概意思是说当你把USB插入DM800后，系统会把USB当做hdd. 
 
换一句话，是不是系统的容量加大了（好像XP加大内存一样），请装flash的试一试（本人装的是BA系统，没有办法试） 
 
谢谢
