Pros: Put the drives in a server to replace my 2 1tb drives that were starting to show there age they have worked well since i got them

Cons: I've had these drives for nearly 3 years they have some data rot but they are still good drives i have them in a zfs mirror configuration and check the drives once a week only 1 drive shows a single pending sector that the drive refuses to replace

Other Thoughts: i would highly recommend these drives for soft-raid configurations

5 all DOA

Pros: none 5 in a row were DOA

Cons: 5 in a row DOA isn't that enough?

Other Thoughts: I paid more for WD over Seagate this time around based on reviews BIG MISTAKE, 5 new wd drives DOA. returned and replaced with Seagate drives which are still working fine. I have used a lot of drives including Seagate, HGST, and Toshiba but EVERY time I get a WD drive I get bad drives, I have to admit first time with doa WD drives but most of the time I have at most 1 year before a wd drive craps out, I have never had an issue with Seagate or even Toshiba or hgst for that matter, in fact I have an old segate drive from 20 years ago that is still working. don't pay more for less go with a Seagate, wd isn't worth the higher price.

Hi Anonymous,

We are sorry to hear about your online shopping experience with the WD Blue Internal hard drive. As you have not received the product as expected, we recommend you to contact to the place of purchase and immediately to get it replaced.

All our products must pass our stringent quality standards before leaving our factory to be free from defects in materials and craftsmanship. We stand behind our products throughout the device's factory warranty period.

It's unfortunate to hear you already returned the WD Blue drive before we had the chance to assist you. On the off-chance you have not already returned the drive, we would appreciate if you contact us for help . You can contact us via phone or email from below contact details.

Hi Colleen P.,

We regret hearing about your experience with WD Blue drive and appreciate your time for providing the feedback. As a troubleshooting step, Please test the drive on Windows using our Data Lifeguard Diagnostics program. If it passes the test we recommend testing another drive bay or SATA port on your system. We have placed a few helpful links below providing more information for your convenience.

"Testing a drive for problems using Data Lifeguard Diagnostics for Windows":
https://support.wdc.com/knowledgebase/answer.aspx?ID=940

If the test is unfortunately inconclusive and you just purchased the drive then you should be able to return it to the place of purchase. However, if you are past their return policy, you can create an RMA through WD and replace the drive under warranty if necessary.

Terrible Product, Save Your Money and Buy Something Else

Pros: None, drive failed after less than four months and minimal use

Cons: Complete waste of money, drive failed and there is no warranty even after only four months of minimal use.

Other Thoughts: Pay the extra money and find a drive that has support and a warranty.

Ordered Three, One was DOA....little worrisome.

Pros: Western Digital drives are my go-to drives for years in personal use and at work. Fast shipment from Newegg, good packaging.

Cons: One of the three drive was the click of death. Makes me worry.

Other Thoughts: Looking to upgrade my RAID 1 data drives set-up from 1TB to 4TB. First two drives were good, rebuilt the RAID no issues. I use the 3rd drive as backup of the RAID1 set-up. Wanted to back-up the RAID set-up, connected and click of death. Thankfully, was able to start the replacement process on Newegg. Now I am a bit worried about the other two drives if they were from the same batch? Hopefully I am not back here updating my review if/when another one dies on me in the next few months.

Broken seal

Pros: Functional

Cons: Construction quality could be better

Other Thoughts: The seal was broken on the drive itself right out of the box so I have to hope Western Digital will cover it under warranty. Even if they will I bought myself the cost of shipping and a chore.
