I had EZ drive installed on WD Hard drive. I updated bios and it shows 2.1 G drive. I reinstalled windows 3 times but it still only shows 503 mg. A techie told me to remove EZ drive which I did. Should I reinstall EZ drive and when it says that the drive is already set up, is it okay to overwrite files? Or do I have to start all over and format C: and lose everything?
