I purchased Norton Ghost 2003 2 days ago & backed up my hard drive yesterday on 5 cd's. Today I downloaded a program called Zip Genius & when I went to uninstall it I noticed my hard drive spinning continuously for 5 minutes. Then a window appeared saying that XP system files had been replaced by an unknown file. I rebooted and I got a black screen saying the windows system root folder was missing!!! I booted into Norton ghost using the floppy. Restored the 5 CD's and PRESTO I'm here writing this post!! Incredible!! Amazing!! AWESOME!! It takes me about 7 hours to re-install XP & all my software & configurations and my wife would have been very mad if she couldn't access the computer all day tomorrow if I had to do a re-install. IT TOOK NORTON GHOST 2003 33 MINUTES TO RESTORE WHAT TOOK ME 7 HOURS. I was thinking about buying DI but the last time I used it I had too many error messages & the new version doesn't allow you to create a floppy boot disk in case of emergencies so what good is it having to wait for a week to get your packaged CD when your computer crashed yesterday. Just not good enough PQ & if their CD gets scratched you're up the creek! Also Norton Ghost is far more reliable & much, much faster than DI. This is what I have found from personal experience. Others may feel different. I too made the STUPID mistake of relying on registry backups. 1 day you're going not going to be able to access windows & no registry backup will help you then.
