Most drives have a read/write head for each platter surface. The heads float on a cushion of air generated by the spinning platter itself. Here we have a view of our RapidSpar unit performing a full disk image. The bad sectors shown in red are caused by loss of spindle RPM before the heads could retract to the ramp….

This can cause additional wear on that area as seen in this screenshot of a PC-3000 surface verification. The blue line shows disk read performance from start to finish. The gradual drop in performance is normal for all hard drives as a result of…
