If you corrupt the drive

1. Get drive to be recognized (but don't open any files on it)

2. Open terminal and get into REPL (if possible)

3. Enter the following

   >>> import storage
   >>> storage.erase_filesystem()

Another option...

If you can't access the PYCUBED drive nor the REPL:

1. Double-click the reset button and have PyCubed mount into bootloader mode

2. You should now see a drive called PYCUBEDBOOT

3. Drag the file below onto the PYCUBEDBOOT drive.
   Be patient! It will restart once the transfer is complete.
   

   erase_m4.uf2

4. Make sure to add all the default files back once you've wiped the memory
