Mounting QNX6 filesystem in Ubuntu - for both Read and Write

Hi,

Is it possible to mount a qnx6 filesystem in ubuntu linux, for READ and WRITE?

I tried below cmd in ubuntu:
sudo mount -v -o rw -t qnx6 /dev/sdb1 /media/cf1

Observed:
mount: warning: /media/cf1 seems to be mounted read-only.
/dev/sdb1 on /media/cf1 type qnx6 (ro)
