Hello everybody.
After upgrading to Karmic my laptop begun having a strange behaviour regarding my external hard drive, a LACIE 500GB disk.
At what seems random times, the hard drive partitions are not automagically mounted by GNOME anymore, and there is no way to mount them manually.
If the drive is already plugged in since boot time, partitions may be already mounted when gnome starts OR be mounted some time later, with the nautilus windows popping up on the screen showing the disk contents.
The same thing when it is hot-plugged: sometimes the partitions are detected immediately, sometimes it takes a while, and sometimes the drive is ignored.
Additionally, even when it's working ok there is a chance that it will suddenly cease functioning, apps cannot write/read files to it anymore causing serious errors (the drive also holds some virtualbox machines' virtual drives).
This is happening on my laptop, a COMPAL HEL80/81 with karmic, and it didn't happen before the upgrade.
I include some output, after that the hard disk has abruptly ceased "functioning", and after i tried unplugging and plugging it back a couple times:

As you can see, the hard drive is indeed recognized as sdc. But:

The node files under /dev are not there!

This goes back in time, as i don't know haow many of that are related to the hard drive...
Finally, just the dmesg output that occurs after unplugging and plugging the drive back:

Any help would be GREATLY appreciated. Thank you very much!
After upgrading to Karmic my laptop begun having a strange behaviour regarding my external hard drive, a LACIE 500GB disk.
At what seems random times, the hard drive partitions are not automagically mounted by GNOME anymore, and there is no way to mount them manually.
If the drive is already plugged in since boot time, partitions may be already mounted when gnome starts OR be mounted some time later, with the nautilus windows popping up on the screen showing the disk contents.
The same thing when it is hot-plugged: sometimes the partitions are detected immediately, sometimes it takes a while, and sometimes the drive is ignored.
Additionally, even when it's working ok there is a chance that it will suddenly cease functioning, apps cannot write/read files to it anymore causing serious errors (the drive also holds some virtualbox machines' virtual drives).
This is happening on my laptop, a COMPAL HEL80/81 with karmic, and it didn't happen before the upgrade.
I include some output, after that the hard disk has abruptly ceased "functioning", and after i tried unplugging and plugging it back a couple times:

As you can see, the hard drive is indeed recognized as sdc. But:
