sDrive Target drive
Description
• This function mounts the drive specified to the target drive (sDrive).
• The CARD RDY LED keeps flashing during the mount processing, and it turns ON once the mount processing is
completed.
• This function can be executed when the status of an SD memory card is "Inserted (unmounted)".
(The status can be checked with the CCPU_GetCpuStatus function.)
• When an SD memory card has already been mounted, this function ends normally without processing.
Use this function to access an SD memory card again without removing it after unmounting the SD memory
card with the CCPU_UnmountMemoryCard function while the power is ON.
This function does not need to be executed since an SD memory card is automatically mounted when it is
replaced.
Precautions
The USB Mass Storage Class-compliant device cannot be mounted using this function.
