Internal hard disk partition is not displayed in Places menu,. My computer icon doesn't open up and show the internal/usb disk.

[Blackbug]

I upgraded to 12.04 to 11.10 yesterday. After that I was not able to open my internal/external hard disk and usb drives.
The 'My computer' icon is not opening up now, which used to display all these information.
Now only information visible is the ubuntu parition.
Nor, the drives are automatically mounted.
