I am not sure whether it is offered around in the first place - there 
would not be any point in doing so because there would be no way to 
claim the partition. The only way it can be claimed is by an image 
filing system returning a filetype, which is then used to interpret 
the partition as an image file, but that only works for <2GB.

So, the partition is either FileCore format, then FileCore handles it 
directly irrespective of its size, or it will appear unformatted.

Nothing stops a program from using sector operations on a disc that 
appears unformatted. Not via FileCore%SCSI though, you would access 
the disc via SCSIFS.
