    I take it you've tried differant drive manufacturers ?
    Or even a differant drive of same manuf. ?
    Seeing as you've moved this same drive(?) across several chipsets &
    possibly mother boards , Leads me to beleive that the difficulty is either with
    the driver or the drive (if it is always the same drive or drive model) .
