I have done as you said ,but my zx1 does not show up as a removable device.
My computer makes no noise when I plug in the USB as it does with an external hard drive I have. The cable is brand new so unless I have been sold a faulty one I don't know the answer. Unfortunately I do not have another computer to try it on
Thank you I will go to the computer shop and see if they can tell me what the fault is .This will take some time- so I will be in touch when I have their answer.
