W406-CE User’s Manual
Introduction
Inserting an SD Card into the Computer
The W406 is equipped with an SD slot. When an empty SD card is inserted into the slot, the
computer automatically formats it in the FAT file system. This process takes a few minutes to
complete. After an SD card is inserted, the embedded computer will create a directory named
“StorageDisk” under the root directory. The “StorageDisk” directory controls access to the SD
storage space. The embedded computer will create a directory called “StorageDisk2” if another
USB storage device is plugged in at a later time.
Connecting a USB Mass Storage Device to the Computer
The USB mass storage device is highly portable between your PC and a computer that does not
support the TFAT system. We suggest that you format your devices with the FAT format. When
the first USB storage device is plugged into the slot on the back of the computer, a directory
named “USBDisk” under the root directory is created in the internal file system as a link to the
storage device. The embedded computer will create a directory called “StorageDisk2” if another
SD storage device is plugged in at a later time.
The following table lists USB mass storage devices that have been tested successfully for
