Well that is a little harsh. Scsiport can support a virtual device, it will just be slow as it will have to use the polling
method to process IO requests. It is possible to convince NT that your virtual miniport hardware has a virtual disk target/lun
on a virtual scsi bus. From the problem description I’d say that the Inquiry, Read Capacity, or initial sector(s) data you are
supplying is bogus. You need to reverse engineer exactly what a real disk supplies and then do the same thing. Good news here,
as Microsoft supplies you with the source code for the disk class driver in the ddk, and that will guide you to exactly what
you need to supply.
