Thanks Graham,
It's been a frustrating journey, often because of my my own crass errors, but just like British Rail, I'm getting there.
One can understand a manufacturer, say Canon (digital cameras) throwing a bunch of engineers at this, sorting out the problems and then saying nothing to anyone. Not even to the SD Card Association. Such that their competitors have to go through the same exercise (read expense).
So the SD Card Association have no feedback that their specification is woefully lacking...which it really is IMHO.
For what I'm doing I've cracked all the necessary items SD-Card wise for reading, all I'm doing now is tidying up my own software. Next comes writing and handling the FAT32 system. I'm hoping that the cards won't be the issue anymore and the write commands are in the same format and have the same constraints as reading. We will see.
