When you mount a filesystem, the filesystem translates your file 
accesses to its own internal structure on the physical media.  You do 
not directly access the physical media, so there is no possible way for 
you to corrupt the physical media, or the partition data stored therein. 
  The only way you could have corrupted it yourself would be if you 
logged in as root, and wrote directly to the device node.
