Hi All,
Given that I’m pretty green on the filesytems, I am trying to figure out the
mechanism of the raw filesytem.
In win2k ifs kit, there is an example about how to filter (attach) to the
raw file system ( ie. L"\Device\RawDisk"). Also I noticed that under
Createfile sdk api, one can open a floppy drive using “\.a:”.
My question is that if I filter mounted volume(s), are we going to see these
kind of open ?
And I suspect that there might be file utilities that needs to open the
device in raw mode ( like fsck etc.) for recovery etc? Another use might be
to dump kernel crash ?
Pls help on these, since we need to know when such a raw device access is
coming.
TIA

Attaching to Raw file system allows to filter requests for unformatted
partitions.
IO from utilities like fsck that open volume for direct access will go to
the file system that is mounted on the device.
