To make backups well, not for continuous operation

I have a heterogeneous network at home (Apple, Windows). Under my MacbookPro the plate runs on EXFAT formatted problems. Except that it sometimes takes a little until it starts. However, under Win7 has suffered genuine. Every now and then it goes smoothly, but mostly a fault is detected in the file system and one we asked the question: "Repair" or "continue without" .. As a result, they can not be described in part, or those jokes occur how can copy only 4GB large files (which should not be the case with EXFAT).
I have several external hard drives, and patches on all computers installed, so that everything is accepted by everyone. As we all know, as there may be problems. With 3 additional HDDs everything radioed quite normal when not.

I gave 3 stars, since they work .. Nevertheless, more or less.

The built-in media player and WiFi are nice. Actually works quite well. Is immediately recognized by the TV (Phillips). Movie playback is good for films up to 6-7GB, then the plate is no longer sending mim comes afterwards ..
The WLAN capable of producing the HDD itself, so you can play on the go wirelessly his files (eg. In a backpack and with the iPhone 4s to the music access) also transmits good. "Click Song" The waiting period until "Play Song" is a little high, but it is .. Is probably faster if you do not deeply buries the desired data in the source system ..

If I'd again have a WLANPlatte, I would resort to another. But also can not say that I am unhappy.
