a raid controller is detected

While attempting to install ctm this warning popped up… First of all I have no idea what a raid controller is even after googling it… Should I not install ctm or is there a way to turn this raid controller off if it is not really important to this laptop… Thank you

This message warns you that CTM is not compatible with RAID.
If you do not know what is RAID and have only 1 hard disk, just ignore it and install CTM.
