This is a true example from one forum online, and this user is searching the best PC cloning software to clone system partition to the new HDD. Before introducing the detailed information about hard drive cloning to you, let's learn some knowledge about clone and copy & paste.

Clone VS Copy & Paste

When referring to PC cloning, many of you probably choose to copy and paste. As a matter of fact, copying & pasting is not cloning. Do you know what is the difference between them?

  • Clone: Disk cloning means the process of copying all the contents of one hard disk to another disk. Unlike simple copying & pasting, hard drive cloning contains some hidden and in-use files. What's more, cloning not only ensures files are all the same but also guarantees the physical locations of files are the same as the source disk.
  • Copy & Paste: As the mentioned content above, simple copying can help to transfer a file from a location to another place, but some additional data including master boot record and the file allocation table can't be copied.

In conclusion, by comparing these two modes, we highly recommend you to do disk cloning which enables you to boot operating system from the destination disk if you want to replace a hard drive containing Windows OS. So, you must ask: are there any other situations you need to clone hard drive in Windows 10/8/7? Is there the best PC cloning software to do disk cloning? Read the following content to find the answers.

When Need to Clone Hard Drive

You probably need to clone hard drive in the following situations:

  • Replace a hard drive: As we have said, it is necessary to do hard drive cloning to replace your hard drive. Usually, if your disk is too small and has encountered low disk space warning due to its insufficient disk space, to use a large hard drive for data storage is a good choice by disk cloning method.
  • Use SSD for better performance: As is well known, SSD is widely used due to its advantages, especially its high read-write speed. Therefore, you want to use SSD as system disk to improve your computer performance.
  • Make a backup: Usually, disk issues, for instance, Windows detected a hard disk problem, system corruption or damage and virus attack always happen. In order to avoid data loss, we highly recommend you to use professional PC cloning software to clone the entire disk to another disk for data backup.

In addition, you may choose to make a disk copy by cloning method in order to avoid OS reinstallation when there is more than one computer with the same configuration or to overcome shortages of hard drive to avoid data loss since nobody knows when damages occur. No matter which situation you meet, to do hard drive cloning should be a good solution.

The Best PC Cloning Software

In order to make a backup, upgrade hard drive or replace an old or wrong disk, we advise you to clone the entire hard drive to another disk which can be an SSD for better disk performance or HD. As dedicated disk cloning software Windows 10/7/8, MiniTool Partition Wizard "Copy Disk" is suitable. How can you clone hard drive to SSD/HDD?


1. Please prepare a hard disk as the target disk which must have enough disk space to hold all data of the source disk.
2. During the process of disk copy, all data on the target disk will be destroyed, thus, please make sure that no important data are saved on this hard drive.

Step 3: Next in the following interface, you will see two copy options listed.

  • Fit partitions to entire disk: this method allows you to copy partitions to occupy the entire disk space of the target disk based on the proportion of original partition size.
  • Copy partitions without resize: the original partition size won't be changed. This option only works when target hard disk size is equal or larger than the source disk size.

1. "Align partitions to 1MB" is checked by default, which is suitable for an SSD or advanced format disk for better improvement.
2. If you want to use a GPT disk as the target hard drive, we recommend you to check "Use GUID Partition Table" option. Then after clicking "Next", a notice will pop out saying "To boot from GPT disk, please remember to change BIOS mode to UEFI".

Step 4: Next this disk cloning software will remind you to change BIOS setting if you want to boot from this new disk in Windows 10/8/7. Click "Finish" to go back to MiniTool Partition Wizard main interface.
