¿Cómo eliminar un file en formatting QNX4 cuando una tarjeta CF está montada como de solo lectura en Linux?

Recientemente, el dispositivo DMA de nuestro laboratorio está roto y el problema que se sospecha está en la tarjeta CF que está en formatting QNX4. Quiero eliminar un file llamado 'calforce.dat' y volver a crearlo calibrando el dispositivo.

Monté la tarjeta CF en mi dispositivo y obtuve este resultado:

famer@iphyer:~$ sudo mount -t qnx4 /dev/sdb1 /mnt/ [sudo] password for famer: mount: warning: /mnt/ seems to be mounted read-only. famer@iphyer:~$ cd /mnt famer@iphyer:/mnt$ ls bin calfreq.dat dma dmasav.dat fit2.dat qgui caldyn.dat calraw.dat dma21cfr.dat dmausr.dat lib sbin calfgen.dat calres.dat dmaclamp.dat etc license.dat test_enu.str calfgres.dat calrpt.txt dmaid.dat exit_case loader usr calforce.dat devi-ads dmamfg.dat fit1.dat loader_image 

Quiero eliminar el file 'calforce.dat', pero el sistema de solo lectura ha denegado todos los commands, como escribir y eliminar.

Comandos como:

 famer@iphyer:/mnt$ sudo mount -o remount,rw /dev/sdb1 [sudo] password for famer: mount: warning: /mnt seems to be mounted read-only. 

no dar ningún resultado

¿Cómo puedo resolverlo?

O, como alternativa, ¿puedo copyr los files de la tarjeta CF a la nueva tarjeta CF? ¿Debo formatear una nueva tarjeta antes de que pueda usarla? ¿Puedo simplemente usar algo como GPart o fdisk para realizarlo?
