Hi,
My driver which does raw i/o against an unformatted partition worked
fine until I installed W2K3 SP1. It now crashes with the following :
Do I have to do something special for raw I/O on for W2K3 SP1?
Thanks in advance.

KERNEL_MODE_EXCEPTION_NOT_HANDLED (8e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003. This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG. This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but …
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG. This will let us see why this breakpoint is
happening.
An exception code of 0x80000002 (STATUS_DATATYPE_MISALIGNMENT) indicates
that an unaligned data reference was encountered. The trap frame will
supply additional information.
Arguments:
Arg1: c0000005, The exception code that was not handled
Arg2: 8083f9cc, The address that the exception occurred at
Arg3: b90204d8, Trap Frame
Arg4: 00000000
Debugging Details:
EXCEPTION_CODE: (NTSTATUS) 0xc0000005 - The instruction at “0x%08lx”
referenced memory at “0x%08lx”. The memory could not be “%s”.
