Bug #164175 reported by KiAnKo on 2007-11-20
Affects Status Importance Assigned to Milestone
linux-source-2.6.22 (Ubuntu)

Bug Description

(This happend first in 7.04 at an older computer but now also at in 7.10 at a newer computer).

I had 2 windows partitions before installing 7.10 and before the first update installation I hade both C (SYSTEM) and D (DATA) at my DESKTOP, in PLACES and also in COMPUTER FILE BROWSER etc.

After the first update (about 70) and a restart, SYSTEM disappeared.

I think it should be /sda1 but it's empty...

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:

( 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.

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.)

Is this issue still a bug?

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