This is my attempt to help others who may want to do the same. First, let me say that ATI worked like a dream. My Sony PCG-K33 came with a Hitachi 60 GB 4500 RPM hard disk. After 1 1/2 years, I had very little room left. I bought a Seagate 120 GB drive, 5400 RPM, 8 MB cache to clone my old drive to. I did much reading, before buying ATI and found that it was highly recommended from several sources, so I bought it and a Adaptec 2 1/2 inch USB 2.0 HD enclosure. Before trying to do the job myself, I asked for tips and suggestions on this board. There were a few replies, but none really helpful and the manual covers so many situations, that do not apply to my need, that it is very confusing. This is how I cloned my drive. IMPORTANT: Please see my addition an the bottom of this post. 1. Installed ATI on the laptop. 2. I placed the new 120 GB HD in the USB enclosure. (DO NOT initialize or format the drive before cloning). 3. I booted my laptop and shut down all running programs in the system tray. I had Norton AV, Webroot Spysweeper, ZoneAlarm Pro, and Norton GoBack. It would be best to disconnect from the internet before closing your AV and firewall. In my case, I just had to slide the switch that disconnects me from my wireless router. 4. I launched ATI in windows. 5. I plugged in the USB enclosure containing the new Seagate HD. 6. I clicked the "clone" option and followed the prompts to clone the old drive to the new one. (One reboot required, it told me when). 7. It took approximately 45 minutes for the cloning operation to complete. As soon as it finished, I disconnected the USB external drive enclosure and shut down my laptop. 8. Next I removed the new Seagate HD from the USB enclosure and put it aside. 9. I removed the battery from the laptop and swapped out the two drives. 10. When I booted my laptop with the new HD in it, ATI put up a blue screen that said it was assigning a drive letter to the new drive, (remember that the new HD was not initialized or formatted), and my laptop said that it "found new hardware", then said "the new drive has been installed and is ready to use". Smooth as silk and no problems at all. Thanks, Acronis. It could not have been easier and I now have double the HD space that I had before. ADDITION TO THIS POST: I was using ATI 9.0 Home. Be sure to DL and install the 3677 patch from the Acronis web site.
