      Hello Abhisek,

      To operate two different drives from the FAT file system you will need the following files:
      1. \third_party\fatfs\port\dual-disk-driver.c.
      2. under \utils folder fswrapper.c and fswrapper.h.

      The demo under \boards\dk-lm3s9b96\qs-checkout demonstrates FAT file system on a microSD card and USB flash drive.

      Regards,
      Sainandan Reddy
