i got a seagate portable HD for backups and such, and it works well, except one issue: it emits so much (electromagnetic?) radiation it actually interferes with my Magic Mouse performance. i know it sounds weird, but i have eliminated any other possible cause - including removing all phones from my house, another computer, and more. in the end, it came to the HD. only when its connected, the MM starts to stutter, doesn't register clicks or scrolls. is there anyway to bypass this, except putting a lead sheet separator?
