Hi Lost896, welcome to the board,

Before getting into more complicated trouble shooting, first, I recommend to make sure your SATA cable is making good connection by wiggle and tug on it. Replace the cables with aftermarket ones when you have a chance. Loosen SATA cable is a know cause for problem of the this type.

Hope this would fix it. Post back.

ive done that i even changed the cables a couple of times thinking it was the problem. vista keeps saying that its going to fail. i cant stay connected to wmc through my xbox unless i block that notification

Well, to be honest lost896..... I would do what vista tells you to, cos otherwise, one of these days, you will lose everything on that drive and it will have somply broken down. So my advice would be to get a new drive!

As for the actual thing you are looking for....I'm sorry, I haven't been able to find it either.

What you could be getting could be a SMART error. In which the hdd tells you that it is working out of specified limits & you should back up all your data. What I would recommend you that run a diagnostic test on the hdd.

theres nothing wrong with it nor is there really any important data that i dont alrady have backed up all ready all i want to know is what vaule do i edit in the reg so the popup of a possible failing hard drive will go away

How can you be so sure that there's nothing wrong with it? The errors do not pop up for nothing. Have you tried third party diagnostic software? Have you tried checkdisk and some other software?
Have you tried the same disk in another computer? If there is nothing wrong with the disk itself, putting it in another computer would mean that it would not generate that same message in another vista machine. If it DOES create that message, then there is something wrong with that disk, whether you can still use it or not. Just means that it's a ticking time bomb, waiting to go off....

I'd try to look for some third party diagnostic tools, if I were you, and try to see if they can tell you if anything is wrong with the disk, and if so, what.

heres a screenshot of what hard disk sentinel has to say about my hdd
is there anyway to fix it or save it

what i've read on the web after a google search on reallocated sectors is that this error cannot be fixed. If I were you, I would check the warranty on that drive. Many drives have several years of warranty, so it might be possible to get it replaced for free.

I would do regular backups of your data. Before you crack the chassis, backup your stuff to an external drive.
