One Hard Drive - Set In Raid
I recently worked on a computer that had a single TB drive, It was bought from a store and no hardware had ever been changed.
While I was working on it I noticed it to be quite slow given the specs it had (no virus's) while rebooting I went in to the bios to make sure things were set up right.
I found that the Hard drive was set in raid, to my knowledge raid is to be set only when having more than one disk.
Later I found that the drive was failing and the computer was given a new drive, so the computer is now fine, but I would like to know if setting raid on a single drive be harmful in any way and also why would the original drive ever have been set in raid?
