Early last night after upgrading Adobe Acrobat my main business/media computer starting acting wonky, the usual solution is a re-boot. This time, right after a restart, the first message I saw saw the dreaded HAL.DLL is missing or corrupted. After a bit of searching I found my XP disk and used the Recovery Console to expand and copy hal.dl_ to the appropriate directory. After a re-boot Windows hung on the splash screen. Now what?

The only solution is usually a complete re-install of XP, all the updates, and all the programs - about a 2-3 day adventure.
I have always had a comprehensive backup plan, music files are backed up to a 2 TB USB drive and data is backed up using the new Qwest online backup service plus once a week I image the C drive using
BootIt Next Generation. An image file is a clone of the hard drive including the boot sectors in a compressed configuration.
I booted the computer with the BootIt boot disk and pasted the 2 day old image to the C drive and went to bed. Six hours later the image was restored and the computer is working as if nothing happened.
The moral of the story is backup, backup, backup. You never know when disaster will strike.
