I am having the same problem but slightly different. I am using a nextar case with wd sata hhd inside. My macbook reads it fine, my toshiba laptop also, but my desk with windows 7 does not. My toshib lap has wn 7 on it.
when I look at devises I can see the HD and when I plug it into the usb it bongs, I just cannot see it in explorer. I have tried mapping but it does not show. when I down loaded the program suggested, it scanned but could not find the HD.
Help.
