Hi All,
I developed a SCSI miniport driver to provide a virtual disk drive using
files.The Disk Manager can find my virtual disk when I mount the disk,but
can not acquire my disk’s size…:(.If I provide my virtual disk as
removable disk,all thing is ok.Why the nonremovable disk can not recognised
by the Disk Manager?Can anybody help me?

Thanks in advance
Donald

You need to support the CHS geometry mode page. I bet that driver is
pig-slow since you will have at least a 10ms delay per-request using a MS
miniport.
