Here's something for all you to consider when buying your next hard drive - Western Digital's disk diagnostic tools only work on Windows.
The Register recounts the tale of Keith Edmunds of Tiger Computing, a company specializing in Linux, who was having problems with a couple of Caviar Green WD20EARS drives. He contacted Western Digital looking for updates diagnostic tools to run on Linux and was told to go buy a copy of Windows:
Western Digital technical support only provides jumper configuration and physical installation support for hard drives used in systems running the Linux/Unix operating systems. In order to run the test using the DLG software, you must install the drive on the Windows computer first because it is not compatible with Linux OS. For setup questions beyond physical installation of your Western Digital hard drive, please contact the vendor of your Linux/Unix operating system.
Edmunds pressed further, and was told the following:
Unfortunately, the drive is question can be tested on Windows only. We manufacture our hard drives, build our software and test them on Windows operating systems only. Therefore, when other operating systems come to play, our technical support is strictly limited. It may not sound fair to you, but I am being honest and I thank you in advance for your understanding.
Something for all you Linux users to bear in mind when next buying a new drive.
