Brilliant Super Duper!
 

I just wanted to say how impressed I am with Super Duper. My mothers computer refused to start after I had downloaded the latest security update and I just booted up the external hard drive, went into SD and copied it back to the hard drive. It was so simple and it worked ! I will now make sure that my daughter uses it as well. It has saved me having to listen to complaints about computers from my mother so it is worth every penny!!

Thanks, maryd -- glad it's working well for you!
