Can anyone tell me if I can connect via USB to a WD Media Player without disconnecting the SATA lead, which is connected to my pc, or does it have to be unplugged from pc. In other words I guess I don't want to be moving the computer to get at the SATA lead.

I'm not sure if i am understanding this right do you need an enclosure for a sata dr that is powered by usb?

No I have a Welland eSATA/USB enclosure, it's connected to pc via SATA, I just wont to check if it needs unplugging from the pc, in order to plug the USB connection to my WD Media Player, or can it be left plugged in. That way I could be adding media to it without unplugging all the time, which tends to wear the fittings.

so you are trying to get two devices to see the hdd at the same time Thats a good question but i don't think it can be done w/out networking and sharing the drive your idea probably will not work and dont take a chance of corrupting the hdd networking would be the better way to go

Thanks anyway, I rather thought that may be the case, which is why I asked first. It's just that that drive is a bit awkward to get at, not to worry I will just have to swap the data from my WD My Book across to this one and use that instead. I was trying to get out of moving everything from a to b and b to a.
