K64F not showing as Flash Drive

Hi, My new Freescale K64F arrived this morning. I updated the mBed firmware as per https://developer.mbed.org/platforms/FRDM-K64F/ All working well. The builtin demo was still working, flashing each of the RGB leds in sequence.

I imported the "ShakeRGBled" program into mBed, compiled and saved it to my mBed flash drive in Windows. I pressed the reset button. The white LED comes on, but the mBed flash drive has disappeared. I have pressed reset, tried different USB ports, re-uploaded the firmware (when I hold the reset button and connect USB it does appear as a 'bootloader' drive. I can see the serial port and drive in Windows device manager... /media/uploads/gjt211/001.png /media/uploads/gjt211/002.png

The mBed drive does not appear in Windows, have I bricked this already? I tried searching google with various keywords and couldn't find a similar problem.

Hoping I have not just wasted $60.

Thanks in advance for any help.

If you have access to MBED disk either in normal or boot loader mode, remove your faulty program binary from the disk and reset the device.
