The S.M.A.R.T. attributes are attributes that a HDD keeps about its health and performance.
I know that the MBR is stored at C,H,S (0,0,1) which leaves no free disc space for the drive to function.
Where on the drive are the attributes stored?

As mentioned in this informative blog post, and as confirmation to @djg's answer, some manufacturers store some information in the service area or negative track area of a drive, while others use memory on the PCB, as mentioned by @Dracs.
