Hi, first post here. you guys are very good, so this newbie appeals to you for help. Gist of questions: After I add a new power supply upgrade, I wish to add two older IDE harddrives from my last machine into new HP Pavilion a1700n running Vista. It has SATA hard drive. I believe I included pics of mobo, but if not, it is Asus a8m2n-la / or in HP it is a NodusM3-gl8E Are my old IDE drives compatible? If so, what are the installation steps I need to follow? THANK YOU !!!
