hi!
could anyone tell me how to distinguish the usb harddisk type on filter driver from normal harddisk?

thank u in advance!

Hi,

Does it work for file filter driver too?
Can I put it in mountcompletion routine? And use the mountvolume
deviceobject as the deviceobject?
Does it work for win2k?

I tried it, and it give me a blue screen during boot for win2k.
But it work fine for win xp.

Thank You!

cheers,
vincent

vincent gambit,???ã?

I also got the DevicePropertyEnumeratorName is STORGE not a USBSTOR! why?
It’s a usb mass storage. I used wrong device object ?
should i use vpb->RealObject or not ?
help!

======= 2003-10-09 17:24:00 ???д???=======

Hi,

Thanks for your reply.
I have tried it.
I not sure whether I got the Physical DeviceObject successfully because the
IoGetDeviceProperty failed for DevicePropertyBusTypeGuid!!!
However it was successful for DevicePropertyDeviceDescription and
DevicePropertyEnumeratorName
First one return me Generic Volume
2nd one Storage
So I guess I did it wronly?
I issue the IRP and call IoGetDeviceObject in MountCompletion routine in
sfilter driver
Hope you can help

thank you very much.

Below is a cut of my code:

BOOLEAN
sfQueryRelations(
PDEVICE_OBJECT pDeviceObject,
PFILE_OBJECT pFileObject,
PVOID *pPhysicalDeviceObject
)
{
PIRP pIrp;
KEVENT event;
IO_STATUS_BLOCK IoStatusBlock;
PIO_STACK_LOCATION pIoStackLocation;
PDEVICE_RELATIONS pDevice_Relations;
PDEVICE_OBJECT pDevObj;

// Initialize the event
KeInitializeEvent (&event, SynchronizationEvent, FALSE);

// Allocate an irp for this request. This could also come from a
// private pool, for instance.
pIrp = IoAllocateIrp (pDeviceObject->StackSize, FALSE);
if(!pIrp)
{
// Failure!
KdPrint((“[sfQueryRelations] IoAllocateIrp Failed…\n”));
return FALSE;
}

// Build the IRP’s main body
pIrp->UserEvent = &event;
pIrp->UserIosb = &IoStatusBlock;
pIrp->Tail.Overlay.Thread = PsGetCurrentThread();
pIrp->RequestorMode = KernelMode;
pIrp->Flags = 0;

// Set up the I/O stack location.
pIoStackLocation = IoGetNextIrpStackLocation (pIrp);
pIoStackLocation->MajorFunction = IRP_MJ_PNP;
pIoStackLocation->MinorFunction = IRP_MN_QUERY_DEVICE_RELATIONS;
pIoStackLocation->DeviceObject = pDeviceObject;
pIoStackLocation->FileObject = pFileObject;
pIoStackLocation->Parameters.QueryDeviceRelations.Type =
TargetDeviceRelation;
IoStatusBlock.Status = STATUS_NOT_SUPPORTED;

// Set the completion routine.
IoSetCompletionRoutine (pIrp, sfQueryRelationsComplete, 0, TRUE, TRUE,
TRUE);

// Send it to the FSD
(void) IoCallDriver (pDeviceObject, pIrp);

// Wait for the I/O
KeWaitForSingleObject (&event, Executive, KernelMode, TRUE, 0);

pDevice_Relations = (PDEVICE_RELATIONS )IoStatusBlock.Information;
KdPrint ((“count d\n”, pDevice_Relations->Count));
pDevObj = (PDEVICE_OBJECT)pDevice_Relations->Objects[0];
KdPrint ((“pDevjObj devtype: x flags x\n”, pDevObj->DeviceType,
pDevObj->Flags));
(PDEVICE_OBJECT) *pPhysicalDeviceObject =
(PDEVICE_OBJECT)pDevice_Relations->Objects[0];

// Done! Note that since our completion routine frees the IRP we cannot
// touch the IRP now.
return NT_SUCCESS (IoStatusBlock.Status);
}

NTSTATUS
sfQueryRelationsComplete(
PDEVICE_OBJECT pDeviceObject,
PIRP pIrp,
PVOID pContext)
{
// Copy the status information back into the “user” IOSB.
*pIrp->UserIosb = pIrp->IoStatus;
if( !NT_SUCCESS(pIrp->IoStatus.Status) )
KdPrint((“ERROR ON IRP!!!: x\n”, pIrp->IoStatus.Status ));

// Set the user event - wakes up the mainline code doing this.
KeSetEvent(pIrp->UserEvent, 0, FALSE);

// Free the IRP now that we are done with it.
IoFreeIrp(pIrp);

// We return STATUS_MORE_PROCESSING_REQUIRED because this “magic” return
value
// tells the I/O Manager that additional processing will be done by this
driver
// to the IRP - in fact, it might (as it is in this case) already BE
done - and
// the IRP cannot be completed.
return STATUS_MORE_PROCESSING_REQUIRED;
}

In sfMountCompletion routine

if (NT_SUCCESS (sfQueryRelations (RealDeviceObject, pIrpSp->FileObject,
&PhyDevObj)))
{
KdPrint ((“Success! DevType x Flags x\n”, PhyDevObj->DeviceType,
PhyDevObj->Flags));
}

regprop = DevicePropertyBusTypeGuid;
ntstatus = IoGetDeviceProperty (PhyDevObj, regprop, sizeof(guid), &guid,
&ulSize);

if (NT_SUCCESS (ntstatus))
{
KdPrint ((“Guid : data 4: x data 1: x\n”, guid.Data4, guid.Data1));
}
else
{
KdPrint ((“IoGetDeviceProperty failed\n”));
if (ntstatus == STATUS_BUFFER_TOO_SMALL)
KdPrint ((“STATUS_BUFFER_TOO_SMALL\n”));
else if (ntstatus == STATUS_INVALID_PARAMETER_2)
KdPrint ((“STATUS_INVALID_PARAMETER_2\n”));
else if (ntstatus == STATUS_INVALID_DEVICE_REQUEST)
KdPrint ((“STATUS_INVALID_DEVICE_REQUEST\n”));
}

vincent gambit,???ã?

but what I want is that the DevicePropertyEnumeratorName is “USBSTOR” not “STORAGE”.
In that case I cannot distinguish it from a harddisk.

Maxim S. Shatskih,???ã?

But I want the whole disk. and how to get the whole disk info.
Thank u!

======= 2003-10-13 10:55:00 ???д???=======

“STORAGE” is the enumerator name for partitions, and not for the whole disk.
