Summary: Bought this hard drive 12/05/2012 Died beyond repair on 06/07/2013!! After 18 years this is the first hard drive I bought that went bad in such a short time period, and it was new!! Will not return because too much data on it. $60.00 just thrown away.
Summary: Mine is just a useless paper weight now. I paid $79 for mine, too, before the price dropped. Sadly, it stayed in the box while I gradually bought the other parts for my new system. That means it was too late to return it by the time I realized the drive is garbage. It was dead within a month of opening the packaging and installing it. Let that be a warning: verify your purchases aren't junk before time runs out on your returns.
Summary: I bought this HDD to replace an existing drive that was getting too small. Within a couple months I was getting SMART notifications that the drive was bad and should be replaced asap. And naturally, that's past the return window for Amazon.
Summary: Ordered two of these. Cloned my system drive to one of them and made it my new system drive. A few days later had some problems so I ran checkdisk - bad clusters. Am returning it. The other drive seems to be working OK (so far). Like the title says - buying drives is a real crapshoot - you roll the dice and take your chances.
Summary: I received this drive today and it was in a loose box with a bunch of other items. It was not secured with bubble wrap or any other packing material, there was plenty of room in the box for the hard disk to move around quite a bit in transit. I immediately starting running the Western Digital Data LifeGuard Diagnostics to write zeros to the disk to prepare it for use. During this time, the disk encountered several write zero errors indicating that the sector is bad.
Summary: Died after 1 week. It had 26 bad blocks and started to freeze every 3 min after the first problem. Amazon's tech support tried different ways to replace it and I got a Hitachi 500Gb but I had to pay ~10$ more, plus the delivery. However, they gave me an amazon credit for this. All in all, this is the 3rd WD I owned. The first one died after 3 years, got it replaced with a refurbished WD through the warranty program, and 2nd one lasted 2 years.
