NTFSD

Hello,
I am developing a FileSystem driver over a SAN.
Sometimes, while debugging my system crashes and gives
the following message.

*** Fatal System Error: 0x00000024
(0x001901FE,0xFC48FAA0,0xFC48F8DC,0x80493C62)

I am not very sure about the 0x24 Error.
Anybody having any idea about this.
Thanks in advance,

It is IFS.
I am also surprised about calls to NTFS

Hi,
I have developed a IFS for NT 4.0.
I want to port it for Win2k,what major differences
does both OS carries with respect to FS.
I know there are some changes in the Driver Entry
point
I have read the Windows NT Device Driver Book By
Anthony Mason which speaks of 3 phases in the Driver
Entry level.Driver Entry does only the initialisation
of the Dispatch routines including IRP_MJ_PNP and
AddDevice.
I am not able to understand the parameter
PhysicalDeviceObject in the AddDevice() routine,
Does it carries any significance with respect to
FileSystem.What if I would like to do is to attach to
a disk with a particular signature written on it.

Second, with regard to IRP_MJ_PNP, what sigificance it
carries with respect to a FileSystem Driver.

Thanks in Advance.
Gurpreet
