Now that your system is running again, plan for the future. Download Bart's PE XP boot ISO image and burn on CD. This will allow you to boot with it and access your files, take a snapshot of the disk to a network location etc. Although you dodged a bullet by running scan disk, it could have just as easily corrupted your volume causing you to loose everything.

I just completed a data recovery service call where the disk was non booting and any attempts to mount it using standard XP tools was not working. Booted with Bart's ran Winternal's disk recovery tool on the Bart boot CD and I was able to recover about 60% of the customer's data. It was a good call, I sold him a tape drive with some tapes and a new hard drive and set up backups to run automatically.

The moral of the story though is, when dealing with a non-booting system, the first priority is always to get the data off before attempting any recovery efforts. Secondary moral: backup your data every night! A fried hard drive should not be that big of a deal, just get a new one and restore from backup!
