The one-star review was from someone that does not own the product. His review was to rant about WD. This drive is less than 3 years old, yet he claimed the drive failed out of warranty, a 3-year warranty. He claimed WD would do nothing. His post was June 2013, so it is impossible for the drive to be out of warranty. All hard drives are susceptible to failure, it is a spinning disk. I have had two WD drives fail and their warranty was excellent for both external and internal bare drives. Go to their website, enter the serial number, and request a drive swap. I had a PATA 500GB drive go bad within the 3 year warranty and they offered me a 1TB SATA since they were out of stock on PATA drives. How could that be bad service? The WD 3TB is a great drive. If he really owned a drive that failed after the warranty expired, then of course WD would not replace the drive. Warranties have expirations.
