I bought Acronis Home True Image 10 to clone my existing drive to a larger one. It has a nice wizard that guides you through this. I was going from a 250GB SATA drive to a 750GB SATA drive. Both drives were connected. The old drive was as it came from Dell. A small partition for EISA parameters or something. The big middle NTFS data partition occupying most of the drive. And a final partition with Dell Diagnostics on it, surrounded by some unused space. I let the Wizard automatically set the sizes of the new partitions. It restarted the computer and entered some command line mode. After a (short) while it says it was successful. I reboot the computer, and the new drive isn't there. Thankfully (unlike some other posts on Amazon), my old drive still was--the program just didn't do anything. Now cloning a 250GB drive should take a few hours, and this was done far too quickly, so I pretty much knew it hadn't been successful. I have since tried manually setting the partition sizes. Nothing. In all cases the new drive is left unpartitioned. I have manually formatted the new drive, and run disktest against it, and it is totally fine. But the cloning operation in ATI 10 Home doesn't seem to do anything... What is going on?
