I use 2 WD My Passport HDDs as storage - one connected to a Panasonic BD recorder, and the second to a Technomate Sat. receiver. Both work fine in these situations. However, when they are connected via USB to my Win10 PC, neither HDDs can be accessed. I am guessing maybe the file structure is different in these recorders, that a PC will not recognise ? Other WDs and the PC USB ports are fine, btw, so my question - is there any way I can get the PC to read these drives ? The WD LEDs light up and seem to communicate, but they are not shown on the "This PC" screen. But they DO show, correctly described, in the "Devices list". I just can't access them. Any help much appreciated. Thanks.
