Unmountable Boot Volume and CHKDSK Fails After Hard Shutdown

My HP computer with XP and a WD2500 hard drive has gone bad on me. I was browsing the internet to a site that had an application that was trying to play a sound file that no longer exists. This brought the machine to its knees. I then killed the IEXPLORE.EXE process that was consuming the most resources. At this point the machine become dispondent. I then manually turned off power via the power button. I wish at this point I had just been patient and waited :(.

Upon reboot I get a black DOS screen telling me that windows failed to start. And I need to choose to boot in a Safe Mode, the last known good setting, or normal mode. None of these work. Given one of my HP boot options I could get a blue screen with the the Unmountable_Boot_Volume error.

So I boot the machine from an XP startup disk (not sure if its the same version as what I was running) and go into repair mode. From the DOS enviroment I see that the partition that contains XP and all my data is not readable when I attempt to look at the contents using "dir". I run a CHKDSK /R from the DOS enviroment. After a very long time it quits at 75% saying there are multiple errors.

My ideas at this point include:

1) Burn a Western Digital boot CD with hard drive diagnostic application and see what this finds. I would have already done this but I need to find a burner.

2) Use the FIXBOOT and FIXMBR commands from the XP startup disk in repair mode. But I fear doing this. Could this make things worse?

3) I am looking at magical SW such as Hard Drive Mechanic or DiskPatch. Do these types of applications actually work?

Does anyone have experience or knowledge of these issues that could recommend a reasonable approach. I fear that I know just enough to make things worse if I do the wrong things.

And I have been very negligent. There is very little backup on this hard drive. I have been thinking about doing it but keep getting distracted. This is a wake up call for the future. My next posts to these forums are going to be on what kind of SW should I use for backing things up.

Thanks in advance for any help. I really hope there is some way to get things going again. It feels like this is a SW issue given the way it crashed but what do I know.

Not much you do is going to make it any worse. Try what you wanted to try. Most likely you've corrupted the boot sector on the drive and need to clear it and reformat it. If the drive is old enough, you should just replace it, even though it probably has not crashed. I replace my drives after 4 years on a schedule. It doesn't eliminate crashes but it cuts them down nearly to zero. All drives crash eventually.
