Question about IRP_MJ_QUERY_VOLUME_INFORMATION

NTDEV

Hi Developers,

I need some help in the follow:

  1. My Filter dispatch IRP_MJ_QUERY_VOLUME_INFORMATION
    to catch floppy disk serial numbers.
  2. I’m reading the boot sector from ‘\Device\FloppyX’
    using ZwCreateFile, ZwReadFile and ZwClose.
  3. The floppy is reading correctly, but when change to
    other floppy, the explorer show an error and crash.

thanks in advance,

Sander.

Something like it is happening to me too and I am working on it. I guess
that when you change the floppy you have to attach to a new device by
intercepting MOUNT_VOLUME calls. Tell me more to see if we can can find
out anything.
