sysutils/smartmontools will let you check the error counts recorded  
via SMART and let you invoke various self-tests and possibly a  
surface scan, depending on what the drive's firmware supports.   
However, to do more thorough testing, the (typically DOS-based)  
utility from the vendor will be somewhat better.
