Wider Problem with these drives
I recieved the HDD in poor packaging and the drive was not working. On that note, I decided to buy this particular model of drive locally. To my surprise, I had to exchange 4 drive before I could get a drive that was functioning. These drives inherently seem to be defective. The noise of the hdd head is quite prominent compared to other drives.

Just sending defective item and creting unnecessary hassle since this is non returnable item.

DEFECTIVE PRODUCT
I am writing to express my extreme disappointment with the recent purchase of a WD NAS 4TB HDD from your store on Amazon. Unfortunately, the product I received was defective, and my overall experience has been nothing short of frustrating. I feel it is essential to inform potential buyers about my negative experience to prevent others from facing similar issues. I strongly advise against purchasing from your store and will be sharing my experience on other platforms to raise awareness. I urge you to take immediate action to improve the quality of your products and the level of customer service provided. Customers deserve transparency and reliability, and my experience with your store has fallen short on both fronts. I hope this feedback serves as a wake-up call for your business to address these issues promptly.

This takes huge returning time
This is not as fit as company claim. I will suggest to buy normal product rather then nas hard disk.
