My System Specs


I agree with you about that - however, that occasional click does not necessarily mean doom. I've had an old maxtor do that and it did it extremely loud as if the head fell out of its place and it lasted 7 years on 24/7 operation and heavy use, it was a 60GB Maxtor. Of course if it does that constantly or frequently it's a bad sign but once in a while I would not worry.

SeaTools is not reliable 100% - I would NEVER rely on SeaTools to predict failure - Why ? Because all SEATOOL does is either check your SMART attributes for Threashold reached condition, or it uses a short DST (which runs a series of smart tests) or a LONG DST, which checks every sector on the disk - so your drive may PASS on all test, BUT in reality be a bad drive that will fail - Why ? Because the diagnostics can accoun for only certain gradual failures or failure like bad sectors, spin retry counts, spinup times, seek errors, write errors, etc - so it accounst for around 30~40% (to be conservative) of failures, BUT seatools is useless to predict other time of sudden failures like mechanical defects (that goes for S.M.A.R.T. too) which is very unreliable lately since most of the failures that occur are due to mechanical problems (motors, spinloc coordinators, bad heads, sudden controller failure!). In my opinion it's a joke that Seagate gives customers the false impression with PASSING results in SeaTools, your drive may be pasing the internal diagnostics and PASS, but have hidden mechanical failure that will occur eventually, and the problem is when it is a sudden and non gradual failure - if it's a gradual one, then by all means, you can detect most of it with the tool, although not all still.

When buying drives, I always buy in pairs - 1 is to be used, and another one is to be used as a cloned 1:1 backup ready to use in case #1 fails and so that I have a disk to use while RMAing the first one or buying a new one, depending on whether it's worth the cost. of course I always run SeaTools only as a means to make sure all sectors on my disk are healthy and that the drive passes the internal tests, but I always keep in mind that drives can fail at any moment regardless, so I am prepared that way to avoid surprises.
