Use WDK10 and windows server 2019.
I created a physical miniport for storport, our miniport can received IOCTL_SCSI_MINIPORT request, but can't receive IOCTL_SCSI_PASS_THROUGH.
I use the sg_utils to test my miniport disk and system disk,(sg_readcap use IOCTL_SCSI_PASS_THROUGH):
sg_readcap.exe output for My miniport disk:
"Windows DeviceIoControl error=87"
"read capacity (10)": transport: ????????"
sg_readcap.exe output for system disk: Everything was in line with expectations
“Last Logical block address=167772159 (0x9ffffff), Number of blocks=167772160”
"Logical block length=512 bytes"
who can help me? why my miniport cann't receive IOCTL_SCSI_PASS_THROUGH/IOCTL_SCSI_PASS_THROUGH_DIRECT request?
