problem is caused with the SD library being one of the first things to be 
initialized in the setup routines.

This needs to be re-worked to probably be initialized later but also 
re-initialized whenever the card is re-inserted.

Have fixed and now SD card removal is detected and recovered from, i.e. data is 
written to the card again when re-inserted.

One gotcha - The SD Library and LCD library share the SPI bus, initialization 
order is important i.e. SD needs to be initialized before the LCD.  

I had problems re-initializing the SD and/or LCD when the card was re-inserted 
due to the SPI bus sharing, so have opted for a simpler solution, that or a 
soft reboot after the card has been re-inserted.  This appears to works nicely.
