Dear All,
I am trying to develop a utility which simulates ‘format DOS command’.
eg. format /fs:NTFS f:
From my search I have come to know that format command passes request
from user level to IOCTL_DISK_VERIFY at kernel level.So I tried to format
a raw disk using IOCTL_DISK_VERIFY in my program (using all required
parameters such as DISK_VERIFY structure,).
But it didnot worked at all.
Are there any other IOCTLs also where format command sends its request to
?
Or Can anybody please suggest any alternative method to proceed for it.
Thanks in advance.
Rohit
I can send you sources for the utility that we use to format our FS -
without any FS specific code of course (so you can’t compile it, but you can
see all requires steps!)
Let me know via private e-mail if you need this.

Can’t you just open a file handle directly to the disk drive and write the
bytes out to construct your FS in user mode?

Actually, I’m curious. I’m aware that FAT and NTFS have a UFAT/UNTFS.DLL
used by format and chkdsk as well as Windows Explorer to format drives. I’ve
never bothered to register my own format utilties into Windows Explorer. Is
it actually possible to integrate one’s proprietary format so that Windows
will automatically add it as an option when you format, so say I replicate
the API found in the DLLs? Is there a registry hack so that it lists another
possible entry for formatting?

To mimic FORMAT, you must be able to write the empty filesystem volume
sector-wise by hand. The FSD cannot do this.

Dear Max,
Yes, I have coded for developing the empty filesystem volume.
Thank to all for the useful suggestions.
Rohit
If anyone asked me for the format utility and didn’t receive it yet,
e-mail me again (your virus scanner might’ve rejected the e-mail as I
attached a C file, which I didn’t zip)
