storage devices. UC-7420/7410 has a built-in auto mount utility that eases the mount procedure.
The first connected USB mass storage device will be mounted automatically by
mount
to
/mnt/sda
, and the second device will be mounted automatically to
/mnt/sdb
. UC-7420/7410

command before you disconnect the USB mass storage device. If
you don’t issue the command, you may lose some data.

that happens, type

to un-mount the USB device manually.
