After the surface has been checked, the number of bad clusters is displayed.
Notes and Precautions
• The chdd command performs a read/verify test three times for all the clusters on the surface of the disk,
increasing the ability to detect damaged clusters. Some damaged clusters may only be detected by test-
ing them several times.
• The time required for checking the surface of a Toshiba 2 GB hard disk (PAMHD002) is about 12 minutes
with the chdd command.
