How to enable a volume readonly in file system driver ?

NTFSD
1

Hello, everyone!

Does anyone know how to enable a volume readonly in file system driver ?

I don’t find how to enable such an attribute like readonly for a volume, when volume information is queried. It works for inodes (files/directories).

Is there a readonly type object, such like cd-rom.

Thanks in advance and Best wishes,

You must make the disk device read-only by responding to the proper
IOCTL send to the disk class driver.

Jamey Kirby,

Which IOCTL ? I could not find it ?

It would be very nice that someone knows it!

Thanks!

Filter the disk volume below the FSD, catch IOCTL_DISK_IS_WRITEABLE and fail it.
