Re: Cannot change permissions on a mountable drive

[Hong F Du]

My problem still persists. I read the manpages of mount and umount and some books too. Then I checked the file /etc/fstab, the entry I am having problem with is: /dev/hda6 /mnt/dosE msdos user,exec,dev,suid,rw,conv=auto,uid=0,gid=100 1 1 I am trying to understand part of this line, Can some one please tell me what this user,exec,dev,suid,rw,conv=auto,uid=0,gid=100 1 1 means, specially exec,dev, suid ,uid=0? What other options do I have? What is the default setting for a FAT16 file system?
