Unfortunately, I had not bought the plate Amazon, otherwise I might have been not chosen WD at the first exchange. Have used a couple of times the disk. After a long break the board requires about half an hour, until it is recognized by the computer, at least so far that you can at least see the Directory. During a backup, it uses however nothing when times missing a few bytes. Check Disk finds 22 defective cluster, the data so I can forget. I use several external hard drives, such as Toshiba, Samsung and manufacturers drive brands in housing Installation (including WD-plates). Maybe it's not the board itself, but the right into tinkered by WD in the Gehäude the plate controler which is no good simply.
