Copies large files very slowly
"I recently used a 7-year-old version of Clonezilla to clone my 2TB hard drive to a larger 4TB one. The process took forever and didn't work!!! I guess I need faster software to help me with this."
Nowadays, most Windows users have the need to clone a hard drive to another one. The reasons vary, like cloning a hard drive to a larger one due to insufficient disk space, cloning to SSD for faster speed, or cloning in Windows 7/8/10 for data backup. Whatever the reason is, it's a fact that disk cloning has become a common requirement.
However, cloning a large hard drive can take a long time with simple copy and paste operations. Obviously, cloning has the upper hand here, but why is that? To understand this, we need to know the difference between copying and cloning.
The difference between "Copy" and "Clone"
What you might be referring to is the difference between shallow copy and deep copy. A shallow copy only replicates the top-level object, whereas a deep copy duplicates the object and all of its child objects. In C++, "cloning" is often the idiomatic approach for deep copying polymorphic class objects.
A clone not only ensures that the files are the same, but also that they are in the same physical location on the source disk. In some cases, files need to be in a specific location to work properly. If they are moved, they will not function. As such, cloning is generally a safer way to copy data.
Here we offer you the fastest way to clone your hard drive – by using a disk cloning software – the Disk Copy tool. It's a simple yet secure disk duplication/clone utility that helps you transfer data and upgrade your HDD at an ultra-fast speed. But before you proceed with cloning, there are some preparations you need to make.
For a visual guide, watch and follow along with this video to clone your hard drive to a larger HDD or SSD quickly:
Step 1: Download, install, and run a disk cloning tool on your computer.
Click “Disk Mode,” then select the hard drive you want to copy or clone. Click “Next” to continue.
Step 2: Select the target disk.
Note: If you are cloning or copying the source disk, the target disk should be at least as large as the source disk, or larger.
If the software prompts you to erase data from the target disk, click “OK.”
Step 4: Check and edit the disk layout.
If the target disk is an SSD, remember to check the box next to “Target drive is SSD.”
Step 5: Click “Proceed” to begin the disk cloning process.
