Still don't get it even now

So… for example, if I want to write a virtual SCSI disk (for example RAM
disk) that will act as a SCSI driver (it’ll response to SCSI2 CDBs) and I’ll
be able to make partitions and format it - what kind of driver should I
write?

thanks,
Ziv

Well… the term “Storage Port Driver” is really somewhat misleading when
used in the context of the conventional XP stacks.

The PORT drivers provide access to a (usually shared) peripheral bus. So,
the SCSI driver (or the 1394 driver, or the PCI driver, or…) is the PORT.
The Disk Class driver is, ah, the CLASS.

One writes monolithic storage PORT drivers to acess a particular type of
storage device or media, in order to bypass the Microsoft supplied SCSI Port
or StorPort drivers.

Wooly terminology, I agree,

For Virtual SCSI Disk write a Scsi Miniport Driver. See the list’s archive
for further details.

We have a SCSI port driver designed just for developing virtual miniport
drivers. We have a disk driver sample that uses a local file to store
the emulated disk.

Contact me if you want more information.

A miniport with a SCSI port library (not with system-supplied SCSIPORT).
There are several such libraries in the market, we sell one.
