Hi. I'm reformatting soon and back when I did my original installation of Windows 7 I forgot to turn on ACHI mode in my bios. I have my 1TB Caviar Black partitioned for 250gb Windows 750gb Storage. Will I have to partition the 750gb that all of my Storage/backup files are on if I switch to ACHI? Or just the Windows?
