Not really..unless it's something ridiculous like 100c

I find O&O Defrag to be the best defrag out there..

Use HDTach to benchmark your hard drive, and post results.

I'll be the first to admit, I have no proof to back up the statement. It was just what I heard. Seems like it is mostly just 3 parts people's opinions, 1 part FUD, honestly. I just don't see a lot of actual proof for either side.

After snooping around a little, it seems like there are quite a few people on both sides of the fence about it.
  • On one side, I find several sites & comments stating that it's true. They say heat can make the hard disk assembly warp, which can cause alignment problems, which in turn could effect the bearings of the spindle motor. If the spindle motor is misaligned, could cause bearing seizure. If the bearing seizes enough, it eventually leads to head crashes.
That seems plausible to me.
  • On the other side, I just found out that Google released a paper on disk reliability. The main thing I found interesting is that they said that temperature and activity levels were much less correlated with drive failures than previously reported. Google also found that failure rates varied significantly according to make and model. (I usually assume most people here know that. ) The funny thing is Google declined to identify failure-prone models. ( ...umm...***? Come on, Google! I wanna see you unleashed like a pitbull!)
I am under the impression most people (myself included) consider Google a reputable company, so I am stuck in between. Oh wells...both sides are interesting to me, none the less.


@TARIQ_786: Don't mean to spam your thread. It kind of relates to it... Glad to hear your HDD seems ok. I am so bad a backing up, I need to get into a better habit of it.


EDIT @DuckieHo: I think they meant over a span of time; heating up & cooling down, over & over again. It would be cool to do that, but I think to prove anything, the test could take a while.

I doubt very very much that temperatures affect hard drive performance. The engineers must have designed the components to operate at nominal temperatures. If the disk assembly is warping enough to affect performance, the engineers should be fired or you should take you HD out of the toaster. You could do some testing... run HDTach with fans a few times and repeat testing with it in a hot case.
Once again...

Are you sure IOBit wasn't reporting disk usage instead of disk performance? It makes much more sense that they mislabeled something.

Why report "disk performance" while defragging? Seems more likely they meant "disk usage"

i would tend to believe this statement myself... seems the most logical explanation.

Either way though, according to the analysis performed by SpeedFan, the drive is healthy regardless of what the defrag software said.

Can you run the other diagnostics and post screen shots of those results as a double check? Someone may notice something in one of those that may be useful or at least confirm the Speed Fan results.
