Actually, Best! But with small obstacles

despite the previously read reviews I opted for the WD My Book for Mac.
For Mac really only because I was the equivalent for Win format too lazy plus the difference in price was only 50 cents.

Super is the plate ansich!
- It runs vibration-free, quiet and reliable. Turn off after longer time even in the sleep mode. These are all reasons why I have decided for the board.
(My old My Book pocket-sized runs, to this day without any problems, while it is not treated prissy and has quite a bit eingebüst on the plastic cover.)

Negatives:
The WD software supplied can be relative. quickly shut down. Simply enter in google (WD mac virtual CD) and you're on the right side on the WDC in step by step the shutdown is described by the Virtual CD. However, in English. (Instructions in German can be found among them as a pdf). Overall, however, it has surely taken 30 minutes to 1 hour.
Well, I knew beforehand but what I really pity think that through this process, although the Virtual CD History is turned off but in the case also lose your lights function. Well, that's always more game Errei and irrelevant for backup, only wenns is bout but also nice when it works.
So the only thing that remains is a mini lamp that indicates whether the drive is running at all. The castle and the filling state are "dead". Say all you see on the image of the plate, you can not see really. The strip is was there, the lock also, but it is without lights and without function. - Very sad !!!

Conclusion:
Again, as a backup disk really recommendable! Only the game Erreien must either use or off entirely ... Sorry!
