Western Digital WD40EFZX WD Red Plus 4TB SATA 6Gb/s 3.5" HDD

Arrived very quickly. Being used in an enclosure as an external backup drive. 4TB version. Packaging was ok (just cardboard rather than foam or bubble wrap) but drive seems fine. Formatted no problem and drive scan shows no errors. Only problem was my older enclosure (IcyBox - over esata) was ok with the previous 2TB drive but couldn't cope with the new 4TB one (both WD) - formatting errors. New enclosure (RSHTech - over USB 3) is fine with it. Very quiet and only slightly warm in its enclosure. Pleased so far.

high durability, noise level zero high speed read and write.. value of money.. Satisfied 100%

Purchased a pair of these drives. Have never looked back. Reliable and that's the way it should be.Using the drives in a SOHO setup for photography. No issuesThis is not the first time for me to set up a SOHO NAS but it has been the most stress free using these drivesDeserves all five stars and more

My 2Tb Seagate Firecuda has been accumulating uncorrectable sectors so time to get it replaced, and not with another Seagate as they die too quickly. Even though it has gone in a desktop I wanted a CMR drive rather than an SMR one as shingling really stifles the write speed and I didn't want the big price increase of a WD Black drive.Ordered a WD40EFZX through Amazon but was sold by and shipped by Ebuyer. Why it was £20+ cheaper through Amazon rather than direct, I don't know.First drive arrived and I plugged it in. It made a weird chirping noise but proceeded to do a full format. It took 27 hours, which seemed odd, but reported no errors. I copied the contents of the old drive on to it, again no errors, but when I verified the copy numerous errors were reported. Deleting the problem files generated more errors and the Crystaldiskinfo SMART report started to show larger numbers of reallocated sectors and eventually started reporting read errors. WDs own data lifeguard also showed the errors and indicated the read errors would be a warranty claim.I filled in the return through Amazon, repackaged the drive and paid the postage to return the drive. From the Amazon site I though I was getting a refund once the RMA had been approved by Ebuyer, however, a few days later a new drive arrived.The second drive was plugged in and it was silent. A full format completed in a fraction of the time and filling the drive with randomly generated files reported no errors. Another reformat and copy the contents of the Seagate drive and all is well.The fact the first drive was faulty was an inconvenience, but it was no ones fault, it was handled correctly, and a replacement was sent. For that I am happy. The only reason why it doesn't get 5* is I did not get my postage refunded.

My Synology NAS had a failed drive. This was the same as the failed drive and was easily added to my NAS to give full back up capability again. No issues with it so far.

After many too's and fro's conversations with the company, before the delivery matter was finally resolved, I have to say that Surplus Drives UK Ltd came up trumps, and I received my order. Albeit a little later than expected. The drive works well, and does it's job. It's worth stating that UPS were totally lacking in professionalism, telling untruths about delivery, and then taking it miles away to a pick up point. Surplus Drives had a hard time with me complaining about the non-delivery, but all is well now, and I am grateful for their patience. I will certainly purchase again from them.

Problems after problems trying to install this HDD. Firstly it came in nothing but bubble wrap, seemed to be used already. Second came the failed installation as it was not recognised by my PC and kept disconnecting when I did get the drive to "work". Every time I went to format the drive, to make it actually store data, it would disconnect. Tried running every diagnostic tool I could find and they had failed. There was also this strange beeping noise that hasn't occured with any other HDD I've owned. My previous HDD was also WD and lasted me 8 years so I know it's not the manufacturer.

I purchased the drive from Amazon UK. After receiving the item, I checked the warranty validity on the support website from Western Digital. I was surprised to find that the warranty was "Out of Region".After checking the Amazon page from which I ordered the drive, I eventually spotted that the item was shipped by Amazon US. This is written in small characters on the right side of the page and you can easily miss it given how busy an Amazon page typically is.On the same part of the page, I could also read: "US imports may differ from local products. Additional terms apply". It is only when I clicked "Learn More", that I was able to read... "Manufacturer warranty will not apply". A well hidden piece of information.I asked Western Digital about the warranty and here is their reply:"...The warranty of your device is global and it is still valid as it is covered by Western Digital.You will potentially face issues when trying to create an RMA while being located in the wrong region, so in case you need to replace your device please contact WD directly and we will be more than happy to do it for you..."If you trust Western Digital to honour their warranty, go ahead and buy the drive.I don't feel reassured by their reply personally.Draw the conclusion you want.Fingers crossed, I will have no issue with the drive. I will take the gamble.
