(on mobo) Ati High Definition Audio on Graphics card Creative SB Audigy 2 All drivers are up to date: Bios for mobo: F9 (newest bios) OS Windows XP Pro on my WD drive, Windows XP 64 pro on my Hitachi drive. Both are full versions. Win7 ultimate is a full version Problem: Im going to try and make this short! First I searched the site for some answers and found nothing that really came close to my problem. So if I missed something, then I'm sorry for the dup.. I got Win 7 Ultamate for Xmas, So I install the the 64bit verson on to may Hitachi 2nd partition. Everything seamed to go without any problems, in fact it was much faster then installing any other OS I've installed. So I check the device manager (habit) no drivers were installed for my sound card. I found this funny as every other OS has aways asked for a disk or something. So I quit out reboot the system. At the boot menu it ask if I wanted to boot Win7 or older Windows. So I choose Win7, at this point a message came up and said device driver missing, put in system disk and boot from it. Instead of looking for a driver it started the hole installation process again, telling me that it needed to move my installed window into another folder. Then countiue on with the installation. At this point I dissided to reboot into Win XP64 format the partition and start the hole thing over. Booted in XP64 started to formatthe partition. Well the process got to the point of writting the disk name and checksum. when it stop and reported itcouldn't format the partiton. Great! At this point I boot up the systems disk (Win7) and tryed to format the partiton before installation. It reported the same thing. Im looking for someone who has ran into or heard of this problem. My next step is to repartition the drive and see if I can recover it. Or is there a freeware software that might be able to recover it. And please, lets not talk about partition magic. Let me note that the Hitachi drive is only 3 month old and prior to this, its not given me any problems. My hole computer is less then 5 months old with the exception of my Sound Card and 3 1/2 drive.
