I just took a look at my fstab file, the NTFS partitions are listed as follows.
/dev/hda1 /mnt/hda1 ntfs noauto,users,exec,ro,umask=000 0 0 # Added by TC
/dev/hda2 /mnt/hda2 ntfs noauto,users,exec,ro,umask=000 0 0 # Added by TC
/dev/hda3 /mnt/hda3 ntfs noauto,users,exec,ro,umask=000 0 0 # Added by TC
Even though the ro option is listed the partitions get mounted as rw according to mtab.
/dev/hda2 /mnt/hda2 fuseblk rw,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096 0 0
If you are just trying to mount rw that should do it for you, if you are also trying to mount ro
then you will have to try something else.
