I am starting to get the dreaded "Hard Disc Not Found" display...which is corrected if I give the IDE cable a bit of a nudge through the vent holes on the top on the unit! Apparently there is something not fully functional with this cable...

Question is...where can i find a replacement?

and as a follow up question.....

would a faulty IDE cable in any way affect the grounding of the unit...for I am getting loads of grould loop noise all of a sudden????
