Ubuntu is becoming read only file system on opening any other drive or browser
My ubuntu(10.10) was working for more than 1 yr.
But recently it has started troubling me. It works fine till i dont open firefox, chrome, my Data drive or window drive or dont insert any external pen drive or hard drive.
But as soon as any one of these things is done, the ubuntu becomes read only file system, and then I cannot open any application like gedit or calculator, etc, and not even synaptic or terminal.
Then at the time of restart it takes around 15 mins for checking and fixing the problems and then agin works fine till any of the above stated things are done.
I dont know why it has started, but last thing which I can thought of is that I had connected my mobile with the laptop via bluetooth.
Kindly help me in this regard.
