Cloning Disk - When and Why Disk Clone is Needed

Updated on Jan 09, 2019 by Brithny to Partition Master

Free disk clone software provided by EaseUS software allows you to safely clone disk, upgrade disk or transfer data to another disk in Windows without losing data.

When do we need to clone the disk

Usually, there are two situations that we need to clone disk: Upgrading hard disk & Rescuing data.

Upgrading hard disk

Clone disk is useful when you want to replace the older smaller hard disk by a newer larger hard disk without installing the Operating System and applications once again. One thing to note is that the medium used as destination medium should be of at least the same size as the source medium or larger to ensure all data will be cloned onto the disk without loss.

Rescuing data

In case of hard disks with defective areas it is especially important to back up data to an intact medium before starting any recovery attempts because the recovery procedure may cause further defects resulting from the inherent exposure of this procedure, while the physical disk clone may cause much less exposure than any other use due to its linear operation. After cloned, you can perform a recovery on the destination disk without fearing any further damages. To recover lost data and partition from the hard disk, Data Recovery Wizard is recommended respectively.

How to Clone the Disk

As the internet becomes more and more convenient, international trade among different countries becomes more and more popular, clone disk is also important in business. International trade mostly depends on the internet to communicate and computers to store vital information nowadays. Just imagine that one day, your business contacts, emails, client database as well as some other important information were lost. Are you sure you can restore them and be back in business soon? Consequently, it is too late to regret that you did not clone the disk to have a backup in advance.

However, we can not always avoid data loss. Sometimes, we delete some specific files by accident or failure; sometimes we lose data because of a hard disk failure as well as virus infection; sometimes our computer even will be stolen by others.

Usually, we do simple back-ups such as file copy like copy and paste. This is fine as long as there are no problems with the file system on the original disk. But as soon as the copy in progress finds a file which can't be copied (for whatever reason, file system corruption say) the copy process stops. Leaving you with the time consuming and rather a mundane task of trying to work out where and why the file copy stopped and what files remain to be copied.
