Hard drive disconnecting and reconnecting

Hi

I'm having a bit of a problem here
My external hard drive (a Hitachi 500GB 2.5" drive) which is connected to a Silverstone RVS02 keeps disconnecting
When I plug my hard drive in (With both USB cables), Windows detects it, but after 5 seconds or so it starts disconnecting and reconnecting every second or so
Once a while I get prompts to format the drive

The disconnects do not stop until I unplug the drive, or at least the data one
I've checked my power options and tried almost everything

This is the only USB device that this happens to, and it only happens on this PC so I don't think it's the enclosure
I've tried other USB ports and this also happens


Any help would be amazing
Thanks

Oh and for more info

This only happens when the data cable is connected to a USB 3.0 port
When it's connected to a USB 2.0 port this doesn't happen
The other computers I tried this on only have 2.0 ports

I've tried updating USB 3 drivers on my motherboard (AsRock Z77 Extreme4)
This is the only USB 3 cable I have though
Could it be the problem?

I recently discovered this problem too.
What is happening is that usb3.0 has some power saving mode that lets the hard drive power down.
Here is the fix.
control panel/power options/change plan settings/change advanced power settings/USB settings /USB selective suspend setting
The set the plugged in option to disabled.

So I've tried this and it worked for the first few minutes
I could read and write data with no problems
But after a while the problem started again

Do you know what I could try?

It worked for me. But, I have no more suggestions. I think it is related to the power issue.
Sorry, out of ideas.

Is it acceptable to bump on Tomshardware?
Does it even work?

In addition to the solution posted above, you should install the latest USB 3.0 drivers.

Also go into Device Manage and locate the USB Root Hubs, go to their properties, then the power management tab, and uncheck the settings in there.

Hi people,

I had the same problem, tried the suggested solutions without success. I updated Intel(R)_USB_3.0_eXtensible_Host_Controller_Driver with one compatible with intel's 4-th generation cpu's and it works :) 

good luck!
