Need help: how to copy one hard drive to another

“I get a 2TB new hard drive and want to replace the old 500GB hard drive in my laptop. But I don’t want to waste much time reinstalling the operating system and the applications, so how do I copy one hard drive to another? Any ideas?”

“I have a large amount of files needs to be transferred to another drive, not only pictures, documents, but also music, videos, programs, because my old drive almost run out of the disk space. Can I just copy and paste them to a new drive? ”

Just like the above cases, many users want to copy hard drive or all the data on it to get rid of insufficient disk space problem. A large drive can give your computer new life, and it will run faster. An SSD will be better if you can make more investment. Also, you may just create a duplicate copy to prevent system crash or data loss.

Simple copy and paste operation works well when you want to transfer a small number of files, but you may be disappointed if you copy hundreds of files or the disk containing OS and multiple installed programs. The process is time-consuming and tedious. Even worse, your computer will fail to boot due to hidden boot files or partition(s) missing.

Well then, is there any easy way to copy boot drive to another drive? You can do so by cloning. Please keep reading below to get the best free disk cloning software and a step by step guide to clone hard drive.
