Regarding my netbook hard drive upgrade - it went great but I forgot that I need a second partition to put my backup files, as backing up over wireless is not always reliable. So I used Partition Magic to chop the 300gb partition into 200 and 100gb partitions.
Once I rebooted, Macrium began throwing an error when I tried to back up the C: to the D: - it turned out that for some reason the Volume Shadow Service was not set to 'automatic', but rather 'manual', and was not starting correctly. Once I set it to auto and rebooted, Macrium worked fine.
