You might switch the following user,umask=0000 for defaults, which allows user write access to the files. There are of course many options available depending on your objectives. FYI, a line in my fstab reads:
/dev/sdb1 /mnt/dos/d vfat user,umask=0000 0 0
This mounts the first partition of the second scsi disk on /mnt/dos/d (I don't want to tie up my whole /mnt mount point with read/write permissions.
