Recently I purchased a My Book 8TB Model from Tata Cliq based on good feedback from @Extreme Gamer who also got the same model but from Amazon. When I got the drive it seemed to be working fine but during my test run of copy pasting a few dozen GBs of data I found out a very serious flaw. The drive was reaching 60C temperature even during the current approaching winter season in Delhi-NCR that too during night time when outside temps are in the range of 15-16C. I tested again on different times of the day & got same result. In fact I found out once the drive is heated up to 63C it won't even go down below 59-60C if you just leave it connected to system doing nothing.
I checked with @Extreme Gamer & found out that he got WDC WD80EZAZ-11TDBA0 model hdd inside his My Book drive while I got WD80EDAZ-11TA3A0. The most significant difference between these 2 models is that WD80EZAZ-11TDBA0 is Helium filled model while mine WD80EDAZ-11TA3A0 was an air filled model(Helium filled hdd models are newest tech & runs cooler on an avg than air filled models). Also this particular air filled model WD80EDAZ-11TA3A0 that I got runs hot even for an usual air filled hdd. You can find reports of this particular hdd model running very hot compared to usual on reddit too from users in US/EU which have much colder climate than India.
Now the icing on cake is that WD gives you recertified drive as replacement so basically if you are unlucky to get a very hot running model inside your My Book 8TB model then you will immediately want to get it replaced & then you will get a recertified drive so basically WD is tricking you into buying a brand new defective product & then replace it with a recertified product. I somehow managed to get it returned on Tata Cliq(that is another long story to tell but at least in the end they helped me much more than WD) but I am not going to leave this matter without highlighting it on all the places I can to warn potential buyers of WD's so called "good after sales support" which I also used to believe before this incident. In fact seagate I found out is much better because they at least not try to play a game of thrones with their customers in the sense that all their external drive models are quite consistent so either you get usual slower running SMR model(for capacities up to 8TB) or faster hotter running(but not this much hot) CMR model(for capacities 10TB & above). In short do not believe in so called WD good after sales support & definitely do not buy any WD My Book 8TB or above model from any place without a solid 10 days no questions asked replacement(aka amazon only).

P.S. Temporarily making it a sticky until this post get enough attention as I think it deserves it. From now on I will never buy any WD external drive where I do not know which hdd model I will get inside.

They run way hotter than my other drives. I have 2 8 tb edaz drives and also 2 8tb ezaz Drives.
and 6 3 tb wd reds.
These run atleast 10 degrees hotter than any of my other hard drives. I was dumb enough to make one of them my parity drive on unraid. my wd red 3 tb run at 35 degrees. the ezaz drives are at 39. These hover around 50 to 52 at the best location of my fractal define r5 diretc at the fans both of them with within 2 inch.... the other ones dont have direct airflow. as much they are still lower temperature.
even my r5 3600 never reaches 54 degrees under full load and mostly idles at 30. These are the hottest components in my server..... they do their job they read just as well as the other ones. BUT THEYRE HOTTTTTTTTTTTTTT.
Before shucking them they ran at 70 degrees in the case. While i did my preclear. i should have taken them back. But i thought it was because of the hard drive case.....
I regret that now.
They idle at 45
they also made some of my other drives hotter as well.
I bought a another 3 all of them edaz drive they all run hot in the case didnt bother shucking them. Theyre terrible 3 of them in my fractal case bring up all the temps to 10C hotter on all my other hard drives im not taking any risks. I sugest to anyone who is using more than 2 at a time to just return them...
Normal unraid temps with 3tb were 32 to 35c. After these 3 that i have already spin up every other drive become 45 degree on mostly idle if theyre in use. They go over 50 all the time at like 23C ambient.... i dont recomend these.
Keep in mind that I use to run 10 3 tb wd reds. and the temps never went above 38c.
Thanks for the pics and update on more EDAZ being as hot. Mine is hitting 64c in the enclosure and I don't want to bother shucking it at this point.
The fact that you used 4 drives and they were all the same shows they do run hot. People say they'll run fine when you take them out but I don't want to run the fan on my Synology at max just to keep these shitty drives from overheating.
The JAAHLE code on the bottom indicates its air and not helium, another datahoarder user figured that out, if the DCM code starts with J, its air, if its H, its helium.
I just got 2 of these as Well from Best Buy, It seems no one still has any real info on them. Also mine run warm, i have one idling at 51c with ZERO data on it. I plugged it in out of the box and just let it sit to see what it would do.
EDIT: I let it sit there for another hour and it got up to around 54 while doing absolutely NOTHING.
If these are in fact data center drives the heat makes sense, most data centers are being HEAVILY cooled and these drives would be fine in those conditions, The data center i b worked for had huge amount of cooling being pumped into every server room to the point you almost needed a jacket to walk in. We dont have these condition in our homes.
I had this HDD and decided to return it. It just feels bit too crazy to see that 60C on temps. Just can't lay my trust on it especially if shucked and not in "cold server environment". I guess those drives just aren't suitable for personal use in general.
