I am trying to clone my laptop drive using Acronis True Image 9 and in the instructions it says that after cloning I must remove the old drive and use the new clone drive. I am using a second external hard drive connected via USB to my Presario 2100 laptop. I do not want to replace the existing laptop built-in hard drive since physically it cannot be done anyways because the external drive is much bigger and cannot fit inside the laptop. All I would like to do is create a clone drive in case, the laptop drive ever goes bad. Then at that point I will replace the laptop drive with a small notebook size drive and then clone the external hard drive (which i had it cloned previously with Acronis) to the new notebook size drive. But my question is, the instructions say "you must remove the old drive after cloning". Does that mean the laptop drive which I will be cloning will no longer be good after the cloning process? Again, all I want to do is to clone the laptop drive but keep using it. I don't plan to use the external drive to boot (I dont think it is even possible to boot from an external drive). I just want to have a clone in case of emergency. I would appreciate your feedback. Thanks.
