CHAPTER THREE - PL3000 BASICS

ADD-ON MEMORY OPTIONS
The PL3000 possesses a non-volatile storage option. In most cases it means
that there is an SD / MMC memory card slot being accessible through the battery
chamber. However, the mobile option of PL3000 changes that memory card slot to
a SIM card slot. If your need is the mobile PL3000 with the extra permanent
storage device, in that case, the PL3000 can be furnished with an internal non-
volatile storage, a so called ‘factory-installed add-on memory’. The factory-installed
memory is always the size of 2 gigabytes. The size of the SD or MMC memory
card installed into its slot can be up to 2 gigabytes, so the memory card can also be
a smaller one such as a 512MB or a 1GB SD memory card.
Logically the extra memory is shown as a ‘SDMMC’ directory off the root of the
file system no matter which of two add-on memory options is in use. To be more
precise, the ‘SDMMC’ is a logical drive name. Windows CE does not use drive
letters, but represent, such as partitions and separate flash file systems, as
directories off the root of the file system. Thus, the SDMMC as a storage volume
can be also repartitioned, if need be. In a Control Panel there is an applet called
‘Storage Manager’ with which you can repartition the SDMMC storage. (For more
information about ‘Control Panel’, see the section ‘Control Panel’ on page 30)
Having said that, it is recommended that the storage like SD memory card is
not repartitioned on the Windows CE device. If you transfer data from your PL3000
to some other system using the SD card as transfer medium, the target system
may not find data because it is not stored in the first partition on the SD memory
card. For example, Windows XP workstation cannot detect the partitions other than
the first one if there is more than one partition on the SD memory card. On the
contrary, in the case of the factory-installed add-on memory, repartitioning may be
recommended if more than one partition assists the maintenance of an application
or clarifies the structure of an application program, for example.
