All of our computers are running XP. In the past we were using the software that came with the new HD as we upgraded to migrate from old to new drive. About a year ago we found that once we migrated with the Western Dig or Maxtor software, the resulting cloned drive had problems with Norton products and other products requiring activation and/or passwords. We have recently upgraded to new Dell computers with SATA drives and Dell's hidden partition system restore. We tried the latest version of ghost for windows and had many problems. Previously, we used Ghost 2003 which ran in DOS. This will not recognize the USB 2.0 external drives we use now. My concern centers around backing up in windows where files are open, etc.. I have found that many file backup programs simply skip over open files which leads to an incomplete backup. Does True Image do a THOROUGH backup in Windows. I have always been much more comfortable backing up through dos. How does it interact with product activation, etc.? I would also like to know what, if any changes are made by trueimage to the MBR as Dell indicated any changes to this "breaks" the systems' ability to restore the hard drive. Thanks for your input.
