Getting Disk handle and sending IOCTL massages with SCSI driver...
KIM JUNG TAE
Hi
I'm working on Scsi miniport driver and
GUI which is communicating with the driver.
They must be supported under NT/2000
I was told that the way to get a handle from a disk is....
hDevice = CreateFile("\\\\.\\C:",
.... );
i got that working... and the next,
I tried to send a message with ...
rDevice = DeviceIoControl(hDevice,
IOCTL_SCSI_MINIPORT,
.... );
At this point, i got failed sending the message to my SCSI driver's
IoControl function...
This occurs only under 2000.
With NT, it's fine... so wierd...
Help me please....

Try CreateFile("\\\\.\\Scsi0" ... ) Scsi1, Scsi2, or whatever number your
device has.

Thanks for your answer.
I have already tried putting every string pointers as possible...like...
\\\\.\\Scsi0 , 1, 2 ... , \\\\.\\PhysicalDrive0, 1, 2.... etc..
There were no problems with CeateFile() function's working
under boths of NT and 2000.
DeviceIoControl() is black sheep... especially in 2000.
it works fine under NT.
But in 2000 with same code, it never works...
I could NOT find any informations about difference between them...
Should i make special INF for 2000 ?

What is the error code?

I.e. a colon must be specified after miniport number! This works both in NT and 2000.
Also note, that at least one device must be attached to SCSI bus otherwise SCSIPORT driver
does not pass IOCTL_SCSI_MINIPORT request to your miniport.

Wasn't there some extra security added to the DeviceIoControl() stuff? I
seem to recall that the process under Win2000 needs a few extra security
tidbids. This was added to prevent a user-written tool to go around NT
security and access any part of disk directly.
