User access to write vfat partition?

Any suggestions would be most appreiciated, Well, vfat has absolutely NO idea about permissions and only limited access modifiers, so there's no way, in the filesystem, to allow a specific user to access a file on a vfat partition without allowing them to access the entire partition. Also, vfat won't allow you to place a symbolic link on it. You can link from your ext2 partition to a directory on a vfat drive, but not vice versa. You're probably getting the idea...vfat is dumb. It was intended for a single-user system and has many limitations associated with it because of that intention. If you're willing to allow this user to have access to your entire partition you can add a group (I called mine windows) and mount the partition as group writable and add this user to the group. Assuming the group you want to use has the GID 101 then you can have an entry in /etc/fstab like: /dev/hda1 /cdrive vfat defaults,uid=0,gid=101,umask=002 0 1 which will mount the drive group writable and owned by the group associated with GID 101.

User access to write vfat partition? [Nevermind]
Doh, never mind, I figured it out. Linuxconf can be a wonderful tool. Thanks anyway, Todd

Many moons ago i had this problem and somewhere I read that certain parameters can be added to the Windows partition data in /etc/fstab. I did this and users can read and write to my Windows partition. Here is my fstab entry: /dev/hda2 /dosc vfat defaults,user,auto,umask=002,gid=101 0 2 Maybe you only need the 'user' bit, but since it works I have left it like this. 'auto', of course, mounts the partition when I boot Linux. Hope this helps. -- Phillip Deackes Using Storm Linux 2000
