Hi,
I have Norton System Works 2008 version 11.02 which includes Go-Back (not sure which version).
Have been running various versions of system works for years, and had previously used Go-Back with older versions of System Works. Go-Back has come in very useful on more than one occasion. As one other poster here said "saved my bacon". 
I had not installed Go-Back on my system since I had purchased SW2008 because I did not have enough disk space available.
Recently I upgraded to a larger hard drive and pretty much did a clean, new install of Windows XP-Pro SP3, as well as a clean install of all my apps and utilities. I ran w/o SW for about 2 weeks before installing to make sure the system is stable. Then installed only the SW portion w/o Go-Back and ran it for about a week. Everything is working fine, and then I decided to install Go-Back and it crashed everything.
On reboot I got "Load Error, press any key to continue". Pressing a key only repeated the error message.
Symantec Tech Support could not help me either (was on the phone with them for nearly an hour), so I started from scratch again with another hard drive because I wanted to examine this drive more closely afterwards (I work for an HDD manufacturer, so fortunately access to HDD's is no issue for me).
After getting back up and running, I see that all data is still on the original drive and that the o/s seems to be in place as well, but the drive can not be recognized (no drive letter, and disk manager says this is is an unformatted partition).
Using Partition Commander 10, I can explore the volume and export any files to drive C: and they are fine. There is also the 8GB go-back file in the root directory. I am tempted to simply delete that file and see if I can get the drive to boot, but so far I have not.
I wanted to post this here first to see if anyone has run into any similar scenario and if there is any way to prevent this from happening again. I would still like to use go-back if possible, but now I am paranoid to try and install it again. It took nearly a week to get everything installed again after the crash, which makes it a huge inconvenience.
And BTW, I also had 2 thumb drives connected in USB slots that had some important data on it. Both of these drive were corrupted as well and I had to spend $45.00 to purchase a "removable media recovery utility" in order to get the data back. This was the most annoying piece of this whole experience.
Any thought or suggestions would be greatly appreciated.
Kind regards,
Udo Jaquet
