Summary: These were among the first terabyte hard drives, certainly the first reasonably priced. The magnetic coating on glass platter technology is going on 5 years old by now, and reports have the coating wearing away, causing increasing read errors until total failure. My drive went, one stormy night, from reliable to "What drive? I don't see any drive." All the electronics, outside and inside the envelope, were fried.
Summary: This hard drive has lasted me years, and it has always performed beautifully. It is really quiet and doesn't put a strain on my system. Transferring data with it has always been a pleasure and I would buy this hard drive 100 times over if I was looking again (Maybe in a bigger size though).
Summary: Bought two of these to upgrade/replace failing Samsung hard drives in my Buffalo Linkstation Pro Duo NAS. They have been spinning 24x7 for over a year now with no issue. They generate very little heat and are relatively quiet. Very happy with the purchase.
Very quiet drive- failed after being installed for less than 8 months though

Summary: Worked great while it lasted- drive failed after 8 months. Giving it two stars though because even due to random freezes / I/O failures all data was able to be successfully extracted. Last week started experiencing random I/O delays where system would freeze while HDD LED was on solid. Initially figured it was a driver glitch / something wrong with the SATA controller on the motherboard.
Summary: I purchased five of the Hitachi 0A38016 drives in March 2009 at $86.99 each for use in a Thecus N5200 NAS running as RAID 5. They replaced five Seagate 7200.10 750 MB drives. The drives (as well as the N5200) have been on 24/7 since April 2009 with no problems. The file index for the data is rebuilt every 12 hours so they get a good workout every day even if the files themselves aren't actually accessed.
Amazon's Frustration Free Packaging is Terrible!!!

Summary: My Hitachi drive showed up DOA thanks to Amazon's lame "frustration free" packaging. The drive was packaged in a static bag and a large cardboard box with no padding or plastic tray to isolate the drive. The drive did not survive shipping because it was knocked around like boots in the dryer and wouldn't even power up.
Summary: I bought this product in July 2009. It worked fine until 1 month ago (Nov/2009). It started to have problems and then I just lost my Windows. After reinstalled it, again I lost everything. Reinstalled as a second HD and it keeps with problems sometimes I can't turn the computer on. Contacted Hitachi's Customers service in Brazil and it is ridiculous the way they deal with customers. Not a valid answer. The manager is always traveling and no response.
