Personally, I wouldn't trust any corrections that Spinrite claimed to make. And yeah, before I get flamed for saying that, I was a supporter of it in the "old days". But later, I read several articles claiming that the Spinrite claims to be able to fix hardware problems (i.e., bad sectors) using only software, were really bogus -- so I quit using it.
Hard drives are so cheap these days, that once one starts to fail, it's better to just replace it than to risk losing data because some utility really didn't fix it.
But ... that's just my opinion.
