I had used my computer on Tuesday morning, let the computer shutdown. Came home from work yesterday and booted it and received this daunting message. I restarted the computer and then it somehow ran a chkdsk /r without me telling it (knowingly). After about 20 minutes or so, computer started normally and all my information was still there as if it was a regular startup. Running XP Pro on desktop computer.

My questions are:
1.) Why did this BSOD show up in the first place? I thought my hard drive was failing, but it booted and is still running fine. Thankfully, I've been backing up/storing my important documents on 2 external drives, but I'd really hate to lose this computer

2.) Is there anything I can do now that the computer is up and running like various diagnostics, etc. I currently use SpeedFan and checked both hard drives S.M.A.R.T. data. Both drives rate highly for performance and fitness; I can post results if anyone would like to see them.

3.) I haven't powercycled my computer since it came on yesterday afternoon, and needless to say, I'm afraid to cause any damage to an already compromised computer. Should I have it restart at any point and just hope?

Thanks ahead of time for any info

Unmountable Boot Volume - http://support.microsoft.com/kb/555302

This error can often be overcome by running the chkdsk /r command on the system partition.

Start/Run...type chkdsk /r and hit Enter. Type Y in new screen and hit Enter. Reboot the system, the command will execute...then boot into XP.

I don't trust smart data very much

You might want to run further diagnostics

Of course you might have had a power hiccup or a gremlin.

No. Try not. Do... or do not. There is no try.

I ran WD hard drive diags for short test and extended test. The extended test found a bad sector and it repaired it, so I think everything looks okay now.

My main questions: basically how did this happen and more amazingly, how did it basically fix itself? I read that most of these errors require a boot cd to repair, yet mine didn't. It appears to have run chkdsk /r on it's own. Seems odd. Anyway, glad it appears to be working just as normally now. I plan on resetting the computer soon, I've left it on since it booted up. I'll post back if any other issues come back.

Thanks guys

It's quite complicated

Keep a close eye on that hard drive and make sure you have all your important data backed up.
