I have installed Win 7 and 2 Ubuntus (both 11.04) on my hard drive on 3 separate partitions. Since yesterday, I've been facing the following problem on the 1st Ubuntu.
Under 'Places' I'm able to see all the partitions under the name I've labelled them. But when I double-click any of them, instead of opening under the file browser (the way the used to before yesterday) and listing the files/folders in that partition, the name of the partition just vanishes from the list and is not to be seen again till a reboot. The same story follows on every reboot. Usually when I double-click, the relevant partition is mounted and is visible on the desktop too. Not so now. But, I have no problem opening the filesystem of the current Ubuntu.
The other Ubuntu install works fine though. It functions as it did before yesterday. Interestingly, I've updated both installs similarly and I've not installed any application outside of the repositories and I only browse with the 'no-script' enabled in Firefox.
So, when I double-clicked the label of the partition and it vanished and went to 'Disk Utility', I was able to see that all the 'vanished' partitions were actually mounted. The mount point was at the 'Media' folder. So, when I went there, I was able to see the names of the 'vanished' partitions'. But I didn't know what files they were. I tried opening them with both 'File Browser'(Error Msg: The location is not a folder) and 'Text Editor' (Error Msg: Could not open the file. You do not have the permissions).
I have no clue as to how to proceed. I'd be glad if someone could refer me to a relevant discussion (I was personally not able to find one) or offer me some guidance. Thanks and cheers!
P.S. I also tried running under the Classic Ubuntu instead of the Unity Desktop. The problem remains the same.
