Mounting or unmounting a storage medium
Generally, a hot-swappable storage medium is automatically mounted when it is connected to the
device. If the system cannot recognize the storage medium, however, you must mount the storage
medium before you can access it.
To remove a hot-swappable storage medium from the device, you must first unmount it to disconnect
it from the device. Otherwise, files on the storage medium or even the storage medium itself might be
damaged.
Restrictions and guidelines
To mount/unmount a partitioned storage medium, you must mount/unmount all the partitions
individually, instead of mounting/unmounting the medium as a whole. To unmount a USB disk, make
sure the system has recognized the USB disk and the USB disk LED is not blinking. Otherwise, the
USB interface or USB disk might be damaged.
Before unmounting a storage medium, make sure no other users are accessing the medium.

Partitioning a USB disk
A USB disk can be divided into logical devices called partitions. Operations on one partition do not
affect the other partitions.
The following partitioning modes are available for USB disks:
Simple—Specify the number of partitions. The system divides a USB disk into the specified
number of partitions with the same size.
Interactive—The system partitions a USB disk according to user input. Each partition must
have a minimum of 32 MB of storage space.
Restrictions and guidelines
It is normal that the specified partition size and the actual partition size have an error less than 5% of
the total memory.
Before partitioning a USB disk, perform the following tasks:
