Can you quantify the difference - say in lines of code for the source or bytes for the object code - between a full-and-complete FAT32 driver and an equivalent driver for your proposed structure? If I may make some criticisms (which are intended to be helpful, of course) of your proposal I would say: The description needs to begin not with what a VP does but what it _is_. For example, "A VP is a specific way to lay out the initial disk blocks of a FAT32 volume, as detailed below. Organising the beginning of the volume in the way suggested allows the software which accesses it to be reduced in size by x%. This, in turn, allows the driver software to be included in a volume boot sector which, at 512 bytes, is not large enough to work with a generic FAT32 volume." "This is often better than having the volume boot sector load a FAT32 driver because ...." Is "virtual partition" the best term? It seems more to be a specific type of FAT32. Perhaps a name like "FAT32mg" would be clearer? (Lots of things could be called virtual partitions.) -- James Harris
