I want to switch out HD to a larger one. Am replacing a Fituji 80gb with a Seagate Momentus 7200.3 320gb. Everytime Acronis is cloning, it hangs and I get "unable to write disc" error message. Retry, ignore, ignore all don't work. When I turned off XP's System Restore I made it all the way to 25% completion before it stopped. That helped, but I need more! Many times, I have formatted, partitioned, ran Check Disk, tested new drive, cache is enabled... to no avail. Here's the info: OS: Windows XP (up to date) Model: Dell Latitude D820 Anti-Virus: AVG 7.5 New hard drive is hooked up externally via a USB. Here is a screen shot of my Disk Management window: http://img258.imageshack.us/img258/408/compmgr.png PLEASE HELP... I'M LOSING MY MIND!!! THANKS!
