file permissons on fat32 disk

Enoon · 10-07-2005, 07:31 AM

Hi I'm currently trying to get filepermissions to write on my fat32 disk as a regular user. Using suse 9.3, I tried editing this in the root-konqueror but it never saved the changes I made. I tried doing it in teh commandline as su with the command chmod o+w *dir* and chmod 777 *dir* but that didn't wokr either.
The permissions it has atm are

drwxr-xr-x

The partitions are mounted under fstab just as auto - no other options.
Eventually I want to recursively get all files on those hds to be write as well as read. I'm wondering do I need to add other options in fstab to make it possible for any user to write on these files? or am I doing something wrong with the chmod? fat32 does allow suse9.3 to write on it - right?? I know mandriva had no problems with it.

thanks for any help

Read/write permissions on a FAT32 partition are set by editing /etc/fstab, not by changing mountpoint permissions. If you could post that file and indicate which partition you want changed, I can show you how to make the edit. Basically, the line in fstab for the partition should look something like this:

/dev/hd** <mount point> umask=0,codepage=850,iocharset=iso8859-1 0 0

where hd** corresponds to the partition you want to change. The important part is "umask=0".

ok this is my fstab:

/dev/sda7 / ext3 acl,user_xattr 1 1
/dev/hdb6 /mnt/leftbrain vfat auto 0 0
/dev/hdb5 /mnt/rightbrain vfat auto 0 0
/dev/sda6 /mnt/thepineal vfat auto 0 0
/dev/sda5 swap swap pri=42 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
proc /proc proc defaults 0 0
usbfs /proc/bus/usb usbfs noauto 0 0
sysfs /sys sysfs noauto 0 0
/dev/dvdrecorder /media/dvdrecorder subfs noauto,fs=cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8 0 0
/dev/fd0 /media/floppy subfs noauto,fs=floppyfss,procuid,nodev,nosuid,sync 0 0

I need all the vfat partitions to be read and write for all users and automatically mounted - do I leave auto as an option there then? to reduce firther problems with this, could you explain the options I will need to put in there?
thanks for your help!

Offtopic I know, but nice naming conventions!

try putting the "showexec" option in. That fstab is kinda weird.

Change the the vfat lines to:

Code:

/dev/hdb6            /mnt/leftbrain       vfat       auto,umask=000                  0 0
/dev/hdb5            /mnt/rightbrain      vfat       auto,umask=000                  0 0
/dev/sda6            /mnt/thepineal       vfat       auto,umask=000                  0 0

Then remount them all as root.
That might do it.
Also, is the sda6 thingy a flash drive? Auto means the device will be mounted at boottime. If it's a removable device you might wanna make it a noauto.
