I just purchased a 160gig Western Digital portable harddrive and it keeps causing power surges and wont work. I have an older (5 years or so) usb2.0 card in it and I am wondering if that could be causing the issue, but I want to make sure before I buy a new one. I tried plugging the HD into a DLink hub with an AC powersupply but it still causes the surges. Western Digital also sells a "power boost cable" but this seems like a stupid solution to the problem, but if it works I guess thats the best solution. See this link. Has anyone on here had a problem with WD USB2.0 drives doing this?
