Hello, last night i've noticed a really sudden speed drop on my HD speed, i've installed a new OS (W7 x64 if that matters), to see if that was the problem, i've also made some test to try and see if it is dying (wich i doubt since it's hardly over 1 year old) and none other than a CRC error of 1 has been found on the HD tune tool, also WF smart test shows unkown values but report the health of the disk as ok, any toughts on what it migth be?
