I'm looking at buying a 500gb external hard drive, and the actual drive itself can only be Western Digital (I won't touch any others, not even Seagate). I can get a 500gb Western Digital Passport for $119.99 CAD in black with the enclosure of course: click here My other option is to buy the drive separately, the Western Digital Scorpio 500gb for $99.99 CAD: click here and a cool case of my liking off eBay for about $13 CAD: click here Now, my question is this; does it matter which case I use in order to make sure the drive is able to be powered with only 1 USB port? I've heard some notebooks dont give enough juice to certain usb ports and would require a y-splitter to use two usb cables in order to power it (im guessing netbooks would probably suffer from this). I remember trying to use a 2.5" lacie external with the orange rubber padding around it, connected it to the front port of a Powermac G5 1.8ghz and it wouldnt mount, unless it was connected to one of the usb ports on the back of the machine. My main interest is to get a cool looking case, the price is slightly less for the customized option, although I don't mind the design of the WD Passport. Thanks!!!
