USB Mass Storage
The UC-7420-LX Plus supports PNP (plug-n-play), and hot pluggability for connecting USB mass
storage devices. The UC-7420-LX Plus has a built-in auto mount utility that eases the mounting
procedure. The first USB mass storage device to be connected will be mounted automatically by
mount to /mnt/sda, and the second device will be mounted automatically to /mnt/sdb. The
UC-7420-LX Plus will be un-mounted automatically with the umount command when the device
is disconnected.
ATTENTION
Remember to type the #sync command before you disconnect the USB mass storage device. If
you don’t issue the command, you may lose some data.
Remember to exit the /mnt/sda or /mnt/sdb directory when you disconnect the USB mass
storage device. If you stay in /mnt/sda or /mnt/sda, the auto un-mount process will fail. If that
happens, type #umount /mnt/sda to un-mount the USB device manually.
