Quite interesting, just yesterday my Evo 840, 1TB died das well. It was 3 
years and one month old! I contacted Samsung service and they claim that it 
has only 3 years warranty. WTF! Lets see what the outcome is.

First the Laptop (ThinkPad T520) was frozen completely. After a restart some 
error messages came up:
-----
Exception Emask 0x50 SAct 0x8 SErr 0x4090000 action 0xe frozen
[...] irq_stat connection status changed

failed command: FLUSH CACHE EXT
ata1.00:status: {DRDY}

ata1: COMRESET failed (errno=-16)
-----
I reinstalled the original HD into the Laptop (openSUSE 13.1 - quite aged 
but still working :-) and could run a smartctl:

-----
T520:/home/docb # smartctl --all /dev/sdb
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.11.6-4-desktop] (SUSE RPM)

If I see it right, it had 19,6 TB written

I tried to reformat as well, but installation of a new system (Leap 42.2) 
always fails die to HD errors.

So, lets wait for the outcome of the warranty case....
