OS X Mavericks doesn't read my external hard drive

Dear Apple Support Community,

Yesterday I bought a new MacBook Pro with OS X Mavericks.

I tried to connect by quite new external hard drive bought in Germany, a Spaceloop 3.0 1.5 Tb by CnMemory.

I can see the external drive on my desktop but it looks like it is empty, although there are something like 600 Gb of data in it.

I reconnected it to my old white MacBook and everything looks fine.

Do you have any suggestion?

Thank you in advance for the help,

Marco

MacBook Pro with Retina display, OS X Mavericks (10.9.2)

So, is USB 3.0 to be avoided? That doesn't sound very promising.

I wouldn’t say avoid USB 3.0, the speed is a massive improvement over 2.0, I’d just be really, really careful with the cables and put as little strain on them as possible.
