[Coco] Why not 5.25 with XP?

[David]

Hi all,

I remember somebody mentioning *ages* ago that it's not possible to use 
Coco disks in a 5.25 drive while running XP

I seem to recall there was a technical explanation given relating to 
hard-coded sector sizes or somesuch which was incompatable with the coco 
disk structure

Is anyone able to shed any light on this, as if the problem is what I 
barely-remember it is, I may have a possible solution...

Anyone got any info?
