About Hard Disk Cloning in Windows 10

Clone disk refers to copy all the data on the disk to another. It is different from copy, because copy may cause error, for example you are not allowed to assess some system files after copy, while the problem will not happen to clone. Actually, besides the situation mentioned above, you can clone hard disk when you need to make a disk duplicate to make double insurance for your data or get rid of secondary damage to the hard disk during data recovery.
