Hi,
Does anyone know what you need to do to be able to format a virtual
disk with FAT on Windows 2000. I can format my drive with NTFS on
W2K and both FAT and NTFS on NT4 - just not FAT on W2K!
The last thing I see before UFAT.DLL unloads is a IRP_MJ_PNP with
a minor code of IRP_MN_QUERY_DEVICE_RELATIONS. The documentation
seems to suggest this is optional for function drivers that don’t
have a bus.
Thanks.
Shaun

one in the NT 4 DDK doesn’t seem to work at all on Windows 2000
(just gives and “Incorrect function” error when you try and access

My virtual disk does work on W2K, it just can’t format the volumes
to FAT. If I format it in to FAT in NT4 and then mount it in W2K,
it works fine!

Shaun,
RamDisk sample for w2k can be downloaded from ms web. I don’t have the link
because they change it on daily base; just try to search for ramdisk. FAT
formating problem is caused by some changes in the FastFat driver. I already
forgot details, it was something with disk verify and verify override flag.
w2k FastFat has some stronger expectation about it than NT4 implementation
and NTFS driver. If you have both NT4 and w2k IFS kits, just compare FastFat
sources and will see what is necessary to change.

Michal Vodicka

It isn’t included but can be downloded separatly. Se:

I recalled this problem in the meantime. In my virtual disk driver I have
following code:
if (IoctlCode == IOCTL_DISK_GET_PARTITION_INFO) {
…
if (BuildNumber > NT4_BUILD_NUMBER) {
// w2k ufat.dll tests if StartingOffset isn’t zero in sectors. We
have to apply this nasty workaround.
PartitionInfo->StartingOffset =
RtlConvertUlongToLargeInteger(Extension->DriveGeometry.SectorSize);
}
else {
PartitionInfo->StartingOffset =
RtlConvertUlongToLargeInteger(0);
}
…
RamDisk code seems different and uses zero there. It sets HiddenSectors to 1
and maybe it also solves the problem.

Nothing at all is “failing” at my level. I tried to handle all
IRPs and all DeviceIoclts that I got. The only one I didn’t know
what to do with was the PnP request to get the related target device.
Hopefully some of the suggestions that others have mention may help.
Thanks

Yep it doesn’t let you do it. The command line format just
says you can’t format a RAM drive. If you re-build the driver
to create devices of FILE_DEVICE_DISK (instead of
FILE_DEVICE_VIRTUAL_DISK) then the command line format says “Error in
IOCTL call”.
My device at least lets you bring up the format window from the
explorer properties and attempt the format. Unfortunately it
just says “Windows was unable to complete the format”. I’m
going to try the suggestions presented by others here tomorrow,
so maybe that will help.

It worked! I set the hidden sectors to one and the partition
number to -1 and that was enough to convince UFAT to format
it.
Thanks again.

Hi!
Check your driver Dispatch for handling IOCTL_STORAGE_CHECK_VERIFY and
IOCTL_DISK_CHECK_VERIFY.
If not you may insert following.
case IOCTL_STORAGE_CHECK_VERIFY:
case IOCTL_DISK_CHECK_VERIFY:
ntStatus = STATUS_SUCCESS;
Irp->IoStatus.Information = 0;
break;
