Lost storage space on FRDM Board

Hi - small question about the FRDM KL25Z ? When I connect the FRDM Board before flashing/ upgrading to the MBED firmware. The FRDM board states that I have 132 MB of flash storage (I copied 120 mb file - so I know there is the space) - BUT - After having put the MBED firmware I know have 172KB storage?

What would be the reason for losing the 130MB ? Anyone else seen or had the same experience?

As there is no external flash, the fat file system is emulated in the RAM of the interface chip. So the size of the disk does not represent a physical storage space but emulates a "fake" file system. As soon as you have a size bigger than the size of the on chip target flash (128 Kb), there will be no difference.
