Hi all,
in my filterdriver I basically filter IRP_MJ_READ,IRP_MJ_READ for volumes.
The PIO_STACK_LOCATION->Parameters.Write/Read.ByteOffset is the
logical offset within a volume, and I’d like to know if
PIO_STACK_LOCATION->Parameters.Write/Read.ByteOffset
- PIO_STACK_LOCATION->Parameters.Write/Read.Length
on dynamic volumes will always be within extent boundaries (W2K and XP) ?
Otherwise, if READ/WRITE can span extents of a dynamic volume, I would have
to split the IRPs.
Regards
Else
