Windows reporting HDD failure

I ran a trial of 7 on my XP Pro Vaio and was getting HDD failure reporting from Windows. I put XP Pro back on and it stopped. I liked 7 better so I put a registered copy of 7 Pro on a couple of weeks ago. The HDD failure reporting got very annoying. I ran the disk check from the manufacture and of course this came up with no errors. I had the added bonus of my operating system being corrupted and had to do another clean install.
I loaded Vaio care on it and was running all the features and noticed self heal had a patch available. It said it was for system crashes. I thought what the heck and clicked to install and the program crashed windows every time I tried. I tried in safe mode same results. I searched on the web and noticed there was the 6.4 version that did not work when Vaio update had loaded it a few days ago. I also noticed there are three versions of it. I looked for a download and there was one on the Asian site. I put this on and the heal patch ran without crashing windows. It did not get rid of the HDD failure reporting. It became less frequent. I was looking at the Intel driver site and they had a chip download. I ran this and the HDD failure reporting has been gone for 9 hours. I did call Sony during some of this and of course I got the How is that my problem routine. I have no problem with the HDD giving up the ghost. That is an easy fix. The thought of putting on another HDD and getting constant interference from windows bothers me more.
Does anybody have any idea what goes on with this. The laptop runs quick there are no BSODs. It reboots faster and runs quicker than it did with XP Pro.
