Physical disk filter driver

OSR_Community_UserOSR_Community_User Member Posts: 110,217
Hello, please help me.
I need to make a driver that protects the boot sector and partitions
sector. So I attach to \\Harddisk0\\Partition1 (for example) and when I
get an IRP_MJ_WRITE call I check
if currentIrpStack->Parameters.Write.ByteOffset is 0 and if so happens
then I deny the write. I set my driver to start at boot time but when I
start my computer it crashes. Can anyone tell me why?

    How you attach itself to the disk driver ?
    Please give more informations and symptoms.
