Cannot write to usb drive after installing gparted

I can mount/unmount. But I cannot write/read anything. Any idea why ? I have checked that I do not have this file :

/usr/share/hal/fdi/policy/gparted-disable-automount.fdi

And I have this line inserted into  /etc/hal/fdi/policy/preferences.fdi :

<merge key="volume.ignore" type="bool">false</merge>

And I have gparted installed ( the problem occured after installing it )

Has some directions for changing gnome automount options, check and make sure these don't include something like "ro" for read-only.  You want the devices to be "rw" for read/write.  (note: I'm assuming that gnome will use the same syntax as the "mount" command for options, if not this is not the case, proper syntax should documented somewhere, I don't personally use gnome).

You might also want to make sure your user account has the proper permissions, i.e. is in the right group to write to automounted drives, I believe that proper group is "storage".  (I'm not sure if you could automount or access the drive at all if this was the case, but check it just to make sure)

Also, I'm assuming you can manuelly mount the drive, if you wish?  You're just having problem with the automounter, right?

Re: Cannot write to usb drive after installing gparted

Sorry, I guess I was thinking "hmm... gparted that uses gtk so that means you're using gnome."

OK, I'm using KDEmod 3.10 and installing gparted doesn't effect my ability to automount.  I'm not sure what the problem here is, since you've probably read the HAL wiki, I'm guessing you've already checked /etc/dbus-1/system.d/hal.conf for errors.  I think I'm out of my depth here, it's possible that the problem is a udev or hal problem, but I'm inclined to think that it's actually KDE at fault here.  If you have another file manager, or something like autofs installed, it's possible that this is actually causing the problem, becuase that other program is actually mounting the volume by it's own method before KDE does. 

Here's some external links to info on HAL and UDEV, but I don't know if they will actually be helpful:

http://reactivated.net/writing_udev_rules.html

There's an obvious test to see if gparted is the problem, pacman -Rs gparted, and see if volumes properly automount again. 

Sorry I can't be more helpful

Edit:

I found a .desktop file in home directory ~/.kde/share/config/mediamanagerrc which contains some options I must have set for mounting a particular USB device, including the "ro" attribute, in this case it's set "ro=false" to allow read/write.

See if you've got a mediamanagerrc file somewhere with "ro=true" applied to some/all devices.
