Different file permissions on vfat

garrik · 06-13-2006, 05:33 PM

Hi all,
I'm trying to share a fat32 partition between winXP and Linux.
I have the following line in /etc/fstab

Code:

/dev/hda1               /mnt/Condiviso          vfat    auto,umask=0000 0 0

but when I type

Code:

[root@Alba ~]# ls -l /mnt/Condiviso/
total 921620
dr-xr-xr-x 12 root root      4096 Jun  7 01:14 Documenti
dr-xr-xr-x  4 root root      4096 Dec 18 11:21 FC4_backup
-r-xr-xr-x  1 root root 943718400 Apr 18 18:42 pagefile.sys
drwxrwxrwx  2 root root      8192 Dec 24 13:36 Recycled
drwxrwxrwx  3 root root      4096 Dec  7  2005 System Volume Information

Why all files do not have the same file permissions? Moreover, why there are some directories without writing permissions?
As far as I know vfat should not support single file permissions...
I have tried to mount partition using default options but still I don't have writing permissions for root!
Please help me!

Try this for your options
umask=000,users,auto,owner,rw 0 0

I have mine as: user,umask=1000,rw,auto 0 0

I have tried some other commands, much more than the following examples, but none has worked.

Code:

mount -t vfat -o auto,rw,uid=0,gid=500,showexec,quiet,umask=0000 /dev/hda1 mnt/Condiviso/
mount -t vfat -o umask=000,users,auto,owner,rw /dev/hda1 /mnt/Condiviso/
mount -t vfat -o user,umask=1000,rw,auto /dev/hda1 /mnt/Condiviso/

I would like to know where I can find, or ask, detailed information on mounting vfat, as I can't solve my problem with mount man page.
Can anyone help?

I have just upgraded from Fedora 4 to 5 and spent the last two days trying to get write permissions to my fat32 partitions, (and other issues) and have tried all the suggestions I came across in the forums... none worked untill this one. Give it a try it may work... seams these solutions change depending on distros and systems.. which it shouldn't since its all the same core but oh well..

One of the lines from my fstab
just make sure you are a member of the group "users" (think its on by default for any created users)

/dev/hda3 /mnt/z_drive vfat umask=0222,dmask=0000,users,rw,exec 0 0

My fstab has this:

vfat rw,users,umask=0 0 0

Thank you all, I tried as you suggested but this doesn't work. I think I can't just keep trying but I must understand what is wrong.
