This is a SMART message, and Wikipedia lists it as a "Potential indicator
of imminent electromechanical failure."

I'm guessing the last error relates to this:

	Uncorrectable Sector Count
	The total number of uncorrectable errors when reading/writing a
	sector. A rise in the value of this attribute indicates defects of
	the disk surface and/or problems in the mechanical subsystem. (or
	Off-Line Scan Uncorrectable Sector Count: Fujitsu)[14]

Time for a new drive, I'd say.
