Visualizing Bad Sectors on a NTFS Formatted Disk
NTFS stores information about file names and directory structure at the beginning of the disk. 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 the read heads being closer to the center of a spinning disk. The red markers on the horizontal axis near the beginning of the disk show unreadable sectors.
