Holy Sh*t!!

Shortly after installing iTunes software (a temporary thing, no longer being used) I started getting a message about "Degraded RAID..." in red letters when I booted the computer. I thought one of my hard drives had failed.

Will getting rid of iTunes and QuickTime fix this? If not, what do I have to do to restore my computer to full health?

Actually... the RAID system was something my computer builder set up. I'm not that fond of RAID, preferring a backup to an external hard drive. How would I convert to that? I am already doing that -- backing up the [broken] raid to a USB drive -- but I wouldn't mind converting my D: RAID drive to independent D: and E: drives.
