Windows explorer disappears when I access my usb 3 hd

[indidginus]

Hi all,

I'm having a very bizarre and infuriating problem where windows explorer often shuts down on me unexpectedly when I am accessing information on my usb 3 western digital hard drive that is attached via my docking station. I have spent about 2 weeks trying to work out what is going on and despite my attempts to fix it recurs....

I have the latest updates from Lenovo
I have the latest bios
I have the latest Windows updates (running Windows 7 Professional 64 bit)
I have the latest intel usb 3 driver for my T430 (core i7 3520M)
I have the latest firmware and drivers for the WD My Passport HD
I have had the docking station replaced by Lenovo

None of this has helped, so if anyone can advise that would be really appreciated as this weird windows explorer issue is making things unworkable for me. I am led to believe that this is a usb 3 issue specifically because the windows explorer issues doesn't seem to happen when the WD HD is plugged into a usb 2 port (or at least for the couple of hours I was running it in that port explorer didn't die).

Michael.
