[C] Creating HDD partition (Format HDD)
When the HDD is replaced or UI data, etc. are downloaded using the USB storage, it is
necessary to format a partition in the HDD before downloading. In this case, the partition is
created in the HDD with this function.
Notes:
• When downloading with a download jig, it is not necessary to format a partition in
advance.
• Perform the HDD partition formatting only when a new HDD is installed since all data in
the current HDD are erased by this operation.
[D] Formatting sRam data (Clear sRam)
When SRAM is replaced with a new one, abnormal values may be written in the new SRAM.
SRAM data must be formatted with this function for such case.
Notes:
• This function is required only when a new SRAM is installed.
• Do not perform this function in cases other than the installation of a new SRAM
because all data in the SRAM will be deleted with this function.
