IOCTL_SCSI_RESCAN_BUS fails on XP,NT4

NTDEV
1

Hello All,
I am issuing IOCTL_SCSI_RESCAN_BUS on the disk to detect the newly
created partitions,drives.Partitions are created by using raw I/O on the
disk.This works successfully on WIndows 2000 but fails for both XP,NT 4.0.
What is the reason and is there any other way to detect these drives.
Thanks for ur time.

Why not use IOCTL_DISK_SET_DRIVE_LAYOUT?

On XP, the PnP reenumeration will help.

Sure I can, But the disk partition table is already written, I just want to
issue something like IoInavalidateBusRelation() from the user mode.For using
IOCTL_DISK_SET_DRIVE_LAYOUT I will have to get the partition information
again ,Initialize the structure and then issue the call.
Is there any simple way?
Thanx
