It's as Jeff said. TRY THE PATCH AT YOUR OWN RISK. IT MIGHT FRY PHY OF YOUR DRIVE. (enough capitals?) Even if you're brave enough to try, DO NOT GO OVER 600mV. 600mV is at least inside specified limits. Also, it won't change anything regarding read errors. All it does is increasing voltage swing while transmitting data (writes). Thanks. -- tejun
