Dear Sr Sorry to pick your email from google, a short Q please! I have a 160GB ATA133 SAMSUNG HDD, I was using it in ATA66 and at less capacity due to an OLD BIOS , I BOUGHT A NEW MOTHERBOARD NOW, AND I WONDER IF I HAVE TO REFORMAT THE DRIVE TO OBTAIN FULL CAPACITY AN DATA RATES losing my data or not. THANKS FOR YOUR ANSWER
