I have an ASUS G75VW-DS73-3D notebook which has 4 USB3 ports and no USB 2 ports.
My Samsung 1TB USB3 HHD (exactly the one reviewed) has given me a lot of trouble and I'm very happy to find out that the problem is the HHD and not my new $2000 notebook as I had previously suspected.
Sometimes the HHD works properly with the correct velocity but at other times it works at USB2 velocity, or my notebook gives me a warning about a power surge or sometimes just shuts downs power immediately. Most of the times I connect the HHD, my ASUS notebook just ignores it as if it wasn't there.
The HHD works better with two other notebooks I have (an orange Sony Vaio and an HP Probook) which both have one USB3 port and 3 USB2 ports. However the Vaio also gives power surge warnings from time to time and the HHD doesn't always work at the right velocity with either.
I'm amazed that Samsung is selling such a piece of junk. The Samsung USB2 HHDs are great - everyone has one and they are very reliable. No-one would suspect that the USB3 version would give such problems. Now I know to look for the official USB3 logo.
Are Samsung or any other manufacturer already producing USB3 HHDs to the official especification?
