    Hi All,

    I am developing a SCSI miniport virtual disk driver. Somehow, the
    system hangs with Shadow Volume Copy Service when a virtual disk drive
    (1G disk size) is present. It works fine if the disk capacity is
    smaller, e.g., 100M.

    I tried to debug, it seems a few write operation (SCSIOP_WRITE) is
    coming to the driver when Shadow Volume Copy Service is used.

    Any ideas?
