Hi
I have used hotplug hard drives for some time but never used eject
Try to sort it out as root and then move on to a normal user
What does mount show when the disk is plugged in?
It should be showing /dev/sdix I believe not /dev/sdi
umount should be working for root but not for a normal user
Brute force enabling of a normal user to mount a hotplug ext disk
For F11
I edited /etc/PolicyKit/PolicyKit.conf to permit "everybody" to mount
<config version="0.1">
<match action="org.freedesktop.hal.storage.*">
<return result="yes"/>
</match>
</config>
or even worse
nedit /etc/PolicyKit/PolicyKit.conf Let root and ja do anything !!!!
<config version="0.1">
<match user="root|ja">
<return result="yes"/>
</match>
</config>
These hacks have changed for F12 !
I am using KDM and XFCE and gnome is installed so what is controlling
udev/hal type things is a mystery to me !
With the hacks above for a normal user the disks get mounted and the
Thunar file manager is opened automatically
However I use pcmanfm to unmount external eSATA disk partitions as they
are all shown in the file manager side panel
