Summary: Bought 6 for a RAID storage server. RAID wouldn't initialize due to drive errors, so my IT department ran a suite of diagnostic tests on them. 3 came back as dead on arrival - right out of the box in sealed packaging. I'll update rating if RMA process works.
Summary: If you value your time and money, stay away! DIGITALET is reselling drives originally sold to system manufacturers. These drives were built by HGST in 2011 and sold in bulk to PC manufacturers. The two I received were date stamped APR-2011 and the other JUL-2011. THEY CARRY NO WARRANTY, as a call to HGST customer service revealed this morning.
Summary: We bought this 2TB hard drive on the recommendation from a friend to back up our media content. The hard drive was great for the first year, then it start to die. We contacted Hitachi tech support who promptly sent out a replacement. We were very impressed with the service and the quick response from Hitachi. The first replacement was dead on arrival.
Summary: Reading reviews here and on other sites, I saw that this drive was poorly rated by many people as there is a very high percentage of failures. Decided to roll the dice and give it a try, but received a drive with many bad sectors. I have never purchased a brand new drive in such bad shape right out of the box. The only saving grace is Amazons easy return policy.
Used four in RAID, TWO DIED after 3.5 years light duty

Summary: I bought eight of these back in 01/25/11, and installed only FOUR into a 4-drive RAID10 setup (keeping remainders unused as spares, sealed in orig packs). My array is run by a SAS9260-4i dedicated RAID controller card. 05/2013 UPDATE: one of the four 7K3000's (0F12115) in the raid array DIED. Those drives were merely in a home server PC that I only run a few hours PER WEEK.
Summary: I bought two of these cheap drives to replace two WD Black drives which recently failed a month apart (both were under 2 years old). First Hitachi mounted once, then failed. Second drive failed after 4 days. They suddenly started clicking/whirring and that was the end. The mechanical hard drive industry has been ugly the last couple years. I don't trust any of them. I recommend keeping 3 or more backups to compensate for the alarming failure rate of any drives over 1 TB.
Summary: I used an external connection to clone my existing drive to this. This succeeded but the drive failed when installing it and hasn't worked since. Be aware this item comes from 3CWorld who in my case shipped it from GameJava Creative. It used to be all orders were handled by Amazon. Now three parties are involved in this purchase, plus the manufacturer.
Summary: We have purchased 3 of these items in July and 2 in August 2012. First order: Two of three were not working at arrival (not appearing in the disk manager at all). They were replaced by the seller quickly and the replacements are currently working. However the third one generates a very loud noise now after less than four weeks of operation. We are in the process of replacing this third item with another brand. Hopefully the seller complies with this wish.
