[Coco] create blank vhd file

[Bob Devries]

Thanks for the replies on this.

I ended up making a blank file of the right number of sectors using a 
Windows programme called HxD.

I then copied it to the SD card, and set it as /sd1, and after changing 
the dmode settings, was able to format it.

I'm still trying to make it bootable. Not successful yet. :(
