In that case, there should be logs indicating the cause of the error 
when it was detected by the kernel.  There's probably something wrong 
with your controller or other hardware.

Every regular file's directory entry on your system is a hard link. 
There's nothing particular about links (files) that make a filesystem

It's probably a similar cause in all cases.  I don't know how many times 
I've seen you on this list defending running old hardware / obsolete 
hardware.  Corruption and failure are more or less what I'd expect if 
your hardware is junk.
