Couldn't be any more obvious that it's 1 defective head out of 6 thanks to this dd analysis. I ordered another of those horrible quality WD 4TB drives to pull the head stack and transplant it into this P.O.S. failing drive to try and get the last files out of it before I throw both of them in the trash. The sixth head gave up a handful of weeks after the 2 years warranty has gone out. I'm never purchasing a WD drive ever again. I've never seen an internal, secondary drive last that short of a lifespan in over 22 years. I've used all sorts of hard drives both in towers and laptops, many brands including Quantum, Maxtor, Hitachi, Toshiba and Seagate. I've never ever seen a 5400rpm, SECONDARY drive in a well ventilated TOWER fail like this in 2 years for no reason. I'll remind readers here that the drive makes NO SOUND whatsoever, no clicking, no grinding, speed up time is super quick, transfer speeds are above 170MB/s on SATA. The drive appears in perfect shape, except for the sixth head, almost completely failed (copies on that platter at 1.8KB/s)

The last 3 storage devices I've had fail:
1x Sandisk 960 GB SSD - 3 years, 33 days
1x Seagate 2TB HDD - ~2 years
1x WD Green 3TB - 5 weeks

Physical drives die. Warranty replaces.
Backups replace your data.

There you go. You proved my point. Besides, warranty is apparently kind of useless with WD drives. People on Amazon have reported not being covered when they should have been. WD is over for me. Not that it was a brand I purchased more than Seagate before, but, now those drives will stay in Thailand for me. No thanks.

I'm not sure what that proved to you, except that "fail" is not unique to a specific brand.
All 3 within or very near the warranty. All replaced via the warranty.

Ah, come on, look at your numbers! [WD fan detected]
Furthermore, you consider 5 weeks near the warranty?!
Anyway, I've decided against buying WD in the future. I've had 2 more people near me report that they have purchased a WD Blue drive and got F by it after a short period of time for no reason. I could understand if it were dropped as an external drive or if it had a power surge (my rig is protected against power surge, BTW) but none of those scenarios happened here. As a matter of fact, nothing happened here. 1 head out of 6 just decided to stop working full speed. It's just Thailand quality, that's what it is. And that's just not worth my time to continue buying this brand. I much prefer investing 10$ more to get a higher quality drive, such as a Seagate (OR ANOTHER BRAND) and move on with my life rather than save 10$ and be stuck in this situation.

I said "within".
Its replacement is still working 4 years later.
I'm not a "fan" of any particular brand. In or attached to my NAS, I have a selection of Toshiba, WD, Seagate.

The Sandisk SSD was "near"....33 days past the 3 year. They gave me a new one anyway.

As mentioned, look at that Backblaze link. I see mostly a 1-2% difference in fail rate across brands.

The WD digust is not against WD directly. It's not exactly a brand boycott I'm doing. They are CURRENTLY producing their WD Blue line in Thailand, it's written on the hard drive. A number of things could go wrong at that factory. Have you ever purchased a diner set made in Thailand? They look sweet AF and after a year, they completely fall apart and I mean the chair posts break, it's absolute garbage. QC might not be done properly, they might not be tuned and/or trained enough to do that kind of QC tests. Either way, it's shameful for WD to let those drives leave the factory and be shipped (perhaps at a very very cheap cost, shipper might be tossing those at full force onto walls and floors, who knows?) but something is not OK. I had WD drives 15 years ago that last a very, very long time, like 10 years old. I would trash the drive just because 120GB was not useful anymore. A 10$ USB stick would be larger, so at that point I would just send the drives to recycling, but THEY WOULD STILL WORK. You know what I mean? I'm at a point where I want to pay extra to get decent quality. I didn't know it was OK in 2019 to ship out defective drives. It's not 1987 anymore.

Anyway, I'm barking at the wrong tree here, but it's good to let a little steam out. Plus, what I post on here will surely help future readers. I should receive the replacement drive (head stack) on sunday. I'll keep posting, eventually we'll how this ends.

A factory in Thailand is by default "bad"?
In reality, yes, for some additional reason, it is. I'm sorry for any Thailand worker reading this but what leaves your factories for North America is sub par quality. I understand this is shocking, but it's what I pay for with my hard worked money and I always ended up losing with what was made in Thailand. Nothing that I purchased lasted a normal amount of time. Diner sets made in Thailand are no exception. It might not be your fault, but anything I purchased made in Thailand has been a scam in terms of quality. Simply put, there is no decent QC in Thailand factories, it seems.

If I had got a WD drive made in China, I probably would have experienced a different amount of drive life time. But who knows... your stats grids don't show the provenance of the drives, so... we'll judge by the brand I guess?

This reminds me of what Apple did when producing the iPhone 4, remember when they split the manufacturing into 2 different providers? The end product should have been of equal quality, but unfortunately, one of them rendered all the iPhone 4s unreliable and battery was not lasting more than 3 hours. IRC, it was FOXCONN vs PEGATRON manufacturers. My GF unfortunately got the wrongly manufactured model and had to replace it. Apple sent her a brand new one for free (1.5 year after purchase) without too much hassle. QC is everything. It's what makes consumers want to go back to your products. Failure after failure is just unacceptable.

Based on the collective experience , every manufacturer has better and weaker series (actually, manufacturers produce only few types due to production optimization, and then sort them in tests to see which piece gets which label): of the WDs, Gold, RED and RED Pro are the most reliable, most frequently those (Green and Blue) dies out of all WDs whom designed for office work (just 8 hours a day, only with few on / offs), with Purple falling between the former two groups. In my servers e.g. I only use REDs (32 of them in the last 8 years) and none have ever died before (OFC I disabled the agressive head parking and they're on UPS).

I'm sorry you ran into this multiple times, I trust you will make the right choice next time. :)

As stated before in this thread, that WD Blue drive was a secondary drive (no Windows, no apps on there) and that computer is on 24/7, no spin down on screen saver (only the display shuts off, I have it so nothing else powers down). It was mostly used as a backup drive in a stationary tower (not in a laptop, not in as an external drive) in a well ventilated case along with 2 other (OLDER) hard drives that still are working perfectly well to this day.

I did not run into this multiple times. This is the first/only time in over 20 years that a hard drive fails like this for no reason and I used perhaps over a hundred hard drives of different brands. But thanks for reading.

I have just received a brand new WD Blue drive that will be the donor for the head stack. I'm now waiting for the head comb kit to arrive from China. This plastic piece is worth 15$ I just can't believe the profit margin on those, it's incredible.

There are always exceptions that strengthen the rules. :)

My fault, I'm tired and mixed someone's post with yours in my head.

You can use a piece of plastic or a shrink tube, but not the headswap is the big deal (if you do it with proper equipment and in clean room), but to find a donor with exact same preamp and with the closely same microjogs, 'cause if the differences more than 200 (rule of thumb), the new heads 'll read close to nothing. I wish you luck, my fingers crossed for you.

I forgot to specify, but I ordered the exact same hard drive model from the same source. The model number is identical.
I was in a hurry before and couldn’t wrote it, the following should match: microjogs, head map, firmware version, drive information table - and most of them not visible outside on the stickers. If a correspondent part (5th-6th-7th, like media, headstack and preamp) of the DCM code identical, site code identical, date of manufacture closest as possible, and you are very lucky, you can even be successful.
