Review: Just Great - I have installed many of these multi-terabyte HGST drives in the past, and their failure rate is commendably low. Failures do happen with all hard drives, and this brand is known for its reliability. These particular drives came in great condition and worked perfectly upon installation. HGST, now a Western Digital brand, has been one I can trust, and I still do. Will gladly buy more of these as needed.
Review: 2 drives DOA - I've had good luck up until this point purchasing refurbished/renewed drives. Unfortunately with my last order of two 18 TB drives, my luck has changed. One drive was recognized by my system but indicated it had 27k+ hours of use (over 3 years) which in itself is fine, however immediately at idle I found the drive was clicking nonstop every couple of seconds which is generally an indication of imminent failure. Second drive would not spin up and was not recognized in 2 different systems. Perhaps drives were damaged in shipping? In any event, requesting refund.

One thing to check when you buy renewed is the serial number. These checked out and when tested were like brand new drives. I love these.
