Summary: Haven't installed them yet, BUT the drives were sold as "NEW" with a 5 year warranty. THE DRIVES SHOW 10/2012 DATE. THERE IS ALSO AN HP STICKER ON IT that states "spare parts" - nearly a third of the warranty period is gone [WD might honor it with sales receipt]. With a MTBF of over a million hours.............................
Summary: To the best of my knowledge, the RE4's are end of life in the sense that WD has stopped using the name RE4 for their enterprise drives. I believe they just call them RE drives now. Anyway, I've used these for various servers and system builds mainly for environments that require RAID. They are peppy enough for what I need and their URE ratings are better in my opinion to other enterprise drives with regards to how much you pay.
Summary: I order two of these drives. They did arrive on time as I expected. After installing the drives into my system, one went bad within a couple of days! After evaluating the drive and moving what few files I had put on it, I tried to overwrite the drive with zeros. The drive completely failed during that process! I have learned the hard way that when a drive has sector errors you should move everything off of it ASAP!
Summary: The product was produced in 2010. There are 5 years guaranty of the HD. So the question is it new? The name of the HD was "Serialnumber - MEDIA" The last production date for this type HD is 2013. Had several problems getting the HD to function!
Summary: This is the 2nd time in 3days i have had to return a drive back to Amazon and WD. Had a really bad week. Apart from the frustration involved waiting for a return and a refund... the working one a solid and fast drive. Only time will tell if this one dies before i receive my RMA Western Digital 500 GB RE4 SATA 3 Gb/s 7200 RPM 64 MB Cache Bulk/OEM Enterprise Hard Drive - WD5003ABYX
Summary: I bought two of these Western Digital RE4 WD2003FYYS 2 TB 64-meg cache drives for use in a quad-processor desktop PC with a Raid 1 configuration, 4-gigs of memory, running Windows 7 (32-bit). When the drives arrived, one was working and the other one had numerous bad sector errors (according to WD's drive evaluation DOS utility).
