Using Windows XP Home and ATI 9.0 Home (3633) After making quite a few image backups of my drive C, I finally worked up the courage to try a restore. Here's what I did: (1) Under Windows, I loaded ATI9 and did an image backup of drive C to a folder on drive D (a second internal hard drive). (2) I then used Windows "Disk Management" to format an external hard drive in a USB box. (3) Still under Windows, I attempted to do a restore from the folder on drive D to the external drive (G) as target. (4) ATI complained that there was a second partition (only about 7 megabytes) in the target drive. I have no idea where this came from as I am sure I never created it and it did not show up under Windows "Disk Management". (5) I approved the deletion of this partition as there was definitely no valuable information on the disk. (6) After about 17 minutes, I got a message "C000B03EB A reboot is required for completing this operation... the operation will be cancelled if you choose not to reboot now" with the choice of "Reboot" or "Cancel". The content of this message seems inconsistent with the title which said "Operation complete". (7) I was unsure whether it was talking about booting off the current running system or booting the newly created system on the external disk. Since I recall seeing messages on this forum warning against rebooting with 2 potentially bootable drives available, I clicked "Cancel" ( The next window to appear said "The operation was completed successfuly [OK]" which also seems to contradict the warning in the previous window. (9) I was still not sure whether I had created a bootable system or not so I decided to browse the external drive using Windows Explorer, only to find that it was not even listed (which I am sure it was before I started the restore). When I clicked on the "remove hardware" tray icon, USB mass storage device was still listed so I removed it and shut the system down. (10) On rebooting and re-attaching the external drive, it does indeed appear to be a copy of drive C. Even the volume label has been changed so that it is now the same as my original drive C. Hopefully, I have achieved my objective of recreating a bootable system, but why do the messages seem so confusing and contradictory? Is it possible to safely test the new disk by booting off it while it is atached to the USB port and my "real" C is still connected? Or do I have to physically swap it with my "real" C drive? Supplementary question... During backup and restore operations, is it a worthwhile precaution to shut down my broadband modem just in case some program decides to update itself in the middle of the operation?
