I have a 3TB external hdd. Initially it worked fine on my ubuntu install(10.04). Upon doing reformatting the drive, as TimeMachine required, and doing a TimeMachine backup I'm not seeing an error message saying the drive is unmountable.

After doing a dmesg | tail, this is what I get:

mansoor@MansoorUbuntuWS:~$ dmesg | tail
