I found a significant problem using demo TI 9. I am using a multiboot system. All OS are windows 2000 (latest updates as of last week). I backup to external USB drive, swapping the drive every few daze to protect the backups. Last night, I ran a full image backup of my system. The USB drive is drive N. I then played with TI's menus and options. Next, I wanted to use the other USB drive, so I unplugged the drive using the proper mechanism in the system tray. To my surprise, when I plugged in the other drive, NO files were listed. So, I unplugged, then replugged the drive, still same problem. So, I then rebooted to one of the other OS (that does not have TI) and voila, the files were indeed still on the drive. I then rebooted back to the OS in which TI was installed. Now, the files were listed but, and I do have a big butt, the drive letter had been changed from N to O!!!!. Note that the drive letter might have actually changed to O when I first plugged in the drive, but, if so, I did notice it because I was more concerned that the files were not listed (since the drive has my latest Retrospect backup) In addition, when I tried touse windows 2000 to change the drive letter back to N, the drive letter was N was not even listed as available! What business does TI have causing my drive letters to change?!!! The backup files themselves can be used to keep track of drive signatures, there's just no excuse. This is a showstopper! I used Retrispect to restore the drive on which the OS lives, to get rid of TIm and, as expected, the drive letter got set back to N when I rebooted.
