Comment 4 for bug 162480

I have a similar problem with my Zip 100 Plus parallel port drive under Hardy. When ejecting a disk, sometimes it unmounts properly, but sometimes it is as if the disk is ejected before hal recognizes that it is unmounted.

Procedure:

1. Connect zip drive to parallel port and run sudo modprobe imm. The zip drive is recognized as /dev/sdg4 and an icon named "Zip Drive" appears in nautilus.

2. Insert a disk. The "Zip Drive" icon changes to whatever the disk name is. My HFS disks are recognized properly, no problems so far.

3. Right click on the zip disk icon and choose Eject. The popup message "Writing to disk" appears.

4a. If I'm lucky the popup message changes in a second to the one saying that it is safe to remove the disk and the disk ejects automatically. The icon changes back to "Zip Drive". The relevant lines from /var/log/syslog are:

4b. If I'm not so lucky the disk is ejected with the "Writing to disk" message still displaying and the icon still displays the disk name. Now /var/log/syslog just has the hald line and nothing from NetworkManager:

Feb 17 11:20:28 amadeus hald: unmounted /dev/sdg4 from '/media/Fonts 5' on behalf of uid 1000

Moreover, umounting manually from the command line and then ejecting works every time. So does gnome-umount -vbd which just gives the following:

gnome-mount 0.8
** (gnome-umount:6944): DEBUG: Unmounting /org/freedesktop/Hal/devices/volume_label_Fonts_3
** (gnome-umount:6944): DEBUG: in unmount_done : user_data = 0x0
Unmounted /dev/sdg4
