What's wrong with my HGST NAS HDD? (EXTREMELY FRUSTRATED)

[boveywong]

I have been using my HGST NAS 4TB HDD and an Orico dock for around 4 months my notebook at home (http://www.amazon.com/ORICO-External-Docking-Duplicator-Function/dp/B00JJEUL5W)

 

Everything was fine until recently the HDD keeps hanging while copying/writing data on it. It has 100% activity but absolutely no I/O happening.

 

It hangs around a minute and it came back normal, after 10s, it hanged again, and this process keeps repeated and repeated again.

 

 

It was so frustrating that I can't recognize what's wrong even when looking at S.M.A.R.T.

 

 

So I wiped everything, recreated a volume and ran surface test using HDDScan, the HDD still keeps hanging, so I gave up and go sleep.

 

The next day I ran the test again, strangely this time the HDD didn't hang, but I got even more frustrated......

 

 

 

HOW CAN A HDD SUDDENLY REACH 300MB/s!? WHAT'S WRONG WITH THE HDD!?

 

No bad sector was found BTW, so what's wrong?

are you sure you didn't put into Clone mode in that dock?

HGST makes some of the best Hard Drives ever . Make sure you didn't do anything wrong to them. Edited January 27, 2016 by alpenwasser

Of course I didn't  :mellow: , and I did checked about that as well.

Yup I knew that's why I went for HGST and even a NAS one for normal desktop usage. That's why I was so frustrated about what happened that it recently

IDK if this will be of any help but that's quite a unusual temperature for a hard drive. It's usually more like 30 degrees or so.

I had HDD's toasty in my nas when my intake fan came unplugged
