I use 0xEC command to get hard disk serial in vxd driver,it’s return is
right when my hard disk is in IDE0 MASTER!But it’s return may be(not must
be^V^) error when my hard disk is in IDE0 SLAVE.
I want to know whether you can get hard disk serial very steady or not…
How can i get hard disk serial steadily!

What does VxD have to do with NT?

IOCTL_SCSI_MINIPORT/SMART_RCV_DRIVE_DATA will return you the IDENTIFY data
for a disk.
Works for old disks without SMART too - the IOCTL is just misnamed.
