Computer hum

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

No not a smelly computer! I have a laptop running PCDJ with a trust
external soundcard. I get an annoying hum when the laptop ir running
and this gets worse when the external HDD spins up. (I have all my
songs on it, but backed up on CDs) Any idead how I can cheaply stop
this? I have seen the earth loop isolators on the PCDJ UK site but they

are15 each and I would need 3 othe them. As we work in Euros here
that is a bit expensive. I have seen ferrite coil things on ebay for a
lot less would they work? All suggestions welcome. Oh and I know it's
early, but happy xmas!
