Unfortunately, that's not good, as it looks more like a problem with the USB drive itself now. :doh: The only netbook I've used my WD on is the Asus EEE (701 model) and can confirm it has no problem reading & writing, as I often carry this Netbook on holidays and back-up my several gigabytes of RAW photos at a time to (from a 16GB SDHC card).
A desktop is definitely worth a try, using a back USB port. If it gives the same problem, I would suggest returning it for a replacement. The WD drive does not require any drivers, so it should work for copying to & from within seconds of plugging in. So far I've used mine on a variety of laptops (Acer, Toshiba, Dell, HP, etc.) and various PCs and don't recall having an issue with any. Only my old desktop PC seems to give the issue for me.
