smart - Is my Hard Drive Failing?

I just tried to run a test on my hdd and it doesn't want to complete a self test. Here is the result:

smartctl --attributes --log=selftest /dev/sda
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.13.0-32-generic] (local build)

So is this disk failing?

Answer

Your drive is very happy to do a self-test; from the summary, it has done more than five of them in the past hour. And all of them have failed, early on in the test, with read errors.

Yes, this hard drive is failing. As the famous Google Labs report said (though I can't put my hand on a link to it at the moment), if smartctl says your drive is failing, it probably is (I paraphrase).

Edit: don't try to save it. Get all the data off it, and replace it.
