Problem in Formatting Filedisk drive with FAT

NTFSD
1

Hi

I am writing Virtual Disk Driver using Filedisk.

My virtual drive is working well when I format it using NTFS.

However, whenever I tried to format it using FAT or FAT32 an error
‘Windows is unable to format the disk’ occurs.

Same error occurs even while using Filedisk as it is.

eg I am using foll. command for Filedisk to mount a file as row disk.

Filedisk /mount 0 c:\file.dat 4M m:

This command mount file.dat as M:.

This drive gets formatted properly with NTFS.

But while formatting it with FAT/FAT32 above error occurs.

Can somebody please let me know why this is happening?

I’ve seen unhandled IOCTL 0x4D0008 while debugging Filedisk. Therefore
I’ve handled corr. MOUNTDEV_NAME IOCTL to return device name properly.

After this it has started giving me other unhandled IOCTL. After putting
that into IOCTL debugger, I got that Device Code id 0x66 and function
name ix 0x6.

Is this related to the formatting problem? Is so, what is solution for
it? I am getting the correct header file for IOCTL.

Please me help to solve this problem.

Thanks in advance.

Why would you use pirated software? Don’t expect much help.

Hi David,

I am sorry but I am not getting which pirated s/w you are talking about.
I believe Filedisk is free for modification and distribution from MS.

Please help me to understand.

Thanks in advance

FileDisk is a ‘supposedly’ GNU Public License disk in a file. It is a stolen work. It was written by Jamey Kirby of StorageCraft and others in that company. It is not a product of Microsoft and never has been. I have used the StorageCraft product in the past and know Jamey Kirby who sold his company. The commercial product has been updated a lot since the pirated version and is very stable.

Any GNU Public License (GPL) product when used and modified by another still carries the GPL restrictions including that source be available for a nonimal charge or free.

Hi David,

Thank you very much for that information.

Being a beginner in driver programming I had never read the lincense agreement carefully. Actually, I am developing this driver for the practice purpose, to know how to build a Virtual Disk Driver. I was thinking about keeping this driver for free download.

Can you please guide me on how should I proceed with the project?

Do you suggest me to recode everything? If so, is there any other sample source that I can use?

Actually, I’ve neerly finished coding with the driver mentioned above and the problem that I mentioned is the last problem that I am facing. On some other websites I’ve seen that many people are facing some problem with the FileDisk.

Please help us to solve the problem.

Thanks in advance.

The commercial product comes with a sample ‘disk in a file’ program and driver. It is a simple project to write one with the library code, so how much of a learning experience can it be? Write from scratch if you want to learn. Google the subject and see where you should not go - such as miniport. The Vista Beta 2 WDK has a ramdisk sample using KMDF. I hear Microsoft has a sample of a ‘disk in a file’ project using iSCSI. There are a couple of libraries still available for creating one of the projects, but with most of the work done for you they are more suitable for commercial projects and not practice.

By Jamey alone, long-long ago, in 90ies I think.

Hi David and Maxim,

Thanks for your help.

I’ve a genuine doubt. Please guide me on this issue.

I agree that it is very easy to make few changes in some ready to use sample. So, it will not give me much learning experience using it.

But, what I think is most of the things are predefined over here. For example, the input parameters and expected results for each IOCTL is predefined. So, even while writing driver from scratch one will need to look into such samples again and again. Then, instead of retyping most of the things from sample, why someone shouldn’t use the sample after going through its minute details? Wouldn’t this make him know more things in short span?

Also, I wonder why we shouldn’t be able to correct some sample in spite of having complete code. Isn’t that a great debugging challenge?

P.S. : While debugging the driver I’ve observed that the message ‘Windows is unable to format the drive’ comes before any unknown IOCTL or MOUNTDEV IOCTL occurs.

That means the problem is only with the data that formatter is reading from virtual drive. Is there something that FAT expects on disk even before formatting it? Can I get the trace of what FAT formatter does exactly?

Please help me to understand.

This is a BIG NEWS for me !!!

Are you sure the FileDisk provided here
http://www.acc.umu.se/~bosse/
and the one in question are the same?

I am interested because prolly I have also used the same as a starting
point for a CD Emulator although later I switched to SCSI miniport
method.

Hi David,

Let’s forget about helping me using Filedisk.

But can you help me understand what exactly do you mean by stolen work?

Using a product under GPL license doesn’t seem big issue as whole Linux
community works with same license agreement.

If it is a ‘disk in a file’ system, I know of no other named filedisk. I
wonder how you got around the lack of an interrupt in the SCSI miniport.
The advantage of the Storagecraft library is that it is a full SCSI port
driver library which makes the whole thing easy. There are supposed to be
some samples using iSCSI. Look at RocketDivision.com for StarPort.

The product is NOT, NOT, NOT under GPL. The source code was copyrighted and those headers and information was removed from the code and it was posted as GPL. Just added a GPL license to someone’s source code does not make it GPL. Do a search on the OSR web site about this issue. This has been said before. Search for Jamey Kirby who wrote the code and not the guy who ‘made it GPL’. He got the code from Jamey and tried to take credit for it being his own code. Just wait until you get a commercial product released and the new owners of the copyright to that code decide you have enough money to make it worthwhile to sue you and prevent your product from being sold in the U.S. and other countries.
