partition disappeared after reboot from desktop, Places and computer

thank you for your report

could you please run this command 'sudo blkid' (without the quotes) and attach the output here

I'm going to jump in on this bug. I have an external hard-drive whose partitions show up on the desktop when I first log into my computer, but they disappear (seemingly) randomly. When they do disappear, they don't show up in mount, either.

This is the output from the command above:

This is my /etc/fstab:

( I am using LVM for my system hard drives. )

There is one other factor:

All of the partitions that disappear are also shared through samba.

This time around, the first indication that something was wrong was that I couldn't see the shares in nautilus / browsing network:///. Then I realized that they were just gone, all around.

Since the information isn't written to fstab, I wasn't sure which mount points I needed to use to remount them. I got the shares back using sudo gnome-mount /dev/ (device listed in output, above)... but ended up with two icons for one of my volumes... still.. it was better than logging out.

Please let me know if you need additional information about this bug.

Sorry. Didn't mention that I'm running Gutsy with all the updates (and a few backports, namely, amarok, and maybe a few others...) BTW, putting the partitions back on the desktop (remounting them) didn't solve my SMB / nautilus problem.

The shortcut is always displayed when I have the LIVE-CD) If I choose COMPUTER from PLACES I only get my DVD and SYSTEM... (see attached picture). I haven't changed anything in any system file...

Anyway...

As "stormzen" I have also had problems with external HDD via USB...

(During the time since January 5, it has been work, but today it disappeared again. This was at my newer computer, about 5 years old (Pentium 4 CPU @ 2.40GHz, with 2GB RAM. BIOS from 2003.

I also have a 10 years old Packard Bell, Pentium 2 @ 450MHz, 376MB RAM (BIOS from 1998 (?)) with the same problem after upgrading to 7.10 - sometimes it seen and sometimes not. Before update I only saw it once... then it was gone. After 7.04 there is an error direct after startup saying that there is BIOS cut at the year 2000 shown on but I haven't noticed any other problems. )

(Today it worked when I tried "blkid" above.)

Below is the same output from the other computer (at this time the partions were seen!!!)

Is this issue still a bug?

Is it fixed, or did it vanish after an upgrade?
