I had taken up the hard drive on another distributor than the current through Amazon. The pictured "Caviar Blue" has a blue sticker; it should be so. Delivered I got a "black Aufleber". Search with serial number on the home page of WD following resulted: Although plate Caviar Blue, but certainly not for the German market and Consumer. Aha! When very friendly phone call to the distributor I was told that this did not matter. So far so good. When loading the operating system WIN7 on the first partition with 80GB install stuck at about 70%. Subsequent formatting with various tools brought it to light: Several defective sectors in this area and irreparably!
Conclusion: Who appoints the board should only accept the original "Blue".
Even the packaging was - like other reviews of various boards - insufficient if not miserable; and as DHL handles packets just in size, should be well known.
A big 5 STARS praise to AMAZON: plate was withdrawn without difficulty even after 34 days and transferred back money immediately; Absolutely exemplary!
I bought spare at Conrad, with blue stickers and consumer release, which runs perfectly; I hope a long time.
