im kinda in a bind. my friend has a mac and i got a laptop (dell, vista 64 bit) and he wanted a couple of pictures i have in my portable hard-drive (western digital 1 tb). so we plug-it into his computer and ......nothing, his mac cant read them. so i eject the drive and we plug it back into my pc, and what happens next is that the laptop makes the sound of as if you just plug something in but you cant see the drive in the control panel. then we went to our neighbor and plug it into his pc and same results, the sound of plug-in something into a pc comes but cant see it. i really hope i didn't fudged something by just plugin into his mac.
