You're probably referring to "fsck". Do a "man fsck" in a "Terminal"  
window for details. A web search of "fsck tutorial mac" will find  
more friendly introductions. Disk Utility's First Aid Verify and  
Repair options are wrappers around fsck.



fsck and Disk Utility's First Aid are not replacements for  
DiskWarrior or the several other disk repair utilities that are  
available for Macs.

Personally I think that the existence of and need for utilities like  
DiskWarrior et al. is a strong indicator of the fragility of Apple's  
file system, but that comes from over 10 years of supporting 100's of  
Solaris boxes that just work, and work, and work ...
