This post from MiniTool Partition Wizard introduces some HDD raw copy tools as well as an alternative. You will need these tools in many situations. Keep reading for more detailed information.

What Is HDD Raw Copy

You might be familiar with disk cloning if you have ever backed up your disk or upgraded your hard drive. It is the process of creating a one-to-one copy of a hard drive. An HDD raw copy is one of the disk cloning methods.

Different from the intelligent sector cloning method that only copies used sectors according to the file system, an HDD raw copy clones all sectors on the hard drive including the partition table, boot records, all partitions, unused sectors, and even logically bad sectors.

In a word, an HDD raw copy is a method of sector-by-sector clone (also known as bit-by-bit copy). Of course, this method usually takes a longer time than only copying used sectors.

You might wonder when you need an HDD raw copy. In general, you can use it when you plan to make an exact duplicate, especially in the following situations:

  • When your hard drive is damaged, you can make a sector-by-sector clone and try to recover data from the copy.
  • With the sector-by-sector clone, you can make a full backup of your disk in case of data loss.
  • If you try to upgrade your hard drive, you can also use this method to migrate your operating system and keep all the data on your hard drive.
  • If you want to copy the entire disk including hidden partitions, a bit-by-bit copy should be a good choice.

Besides HDD Raw Copy Tool, you can also use AOMEI Backupper to do an HDD raw copy. It is a professional data backup program that can be used to clone hard drives, migrate data, make automatic/full/incremental/differential backups, and sync local files and folders to another device.

The AOMEI Backupper Standard version is free to use and it also supports various operating systems, including Windows 10/8.1/8/7/Vista/XP.

Similar to HDD Raw copy Tool, AOMEI Backupper requires that the target drive can’t be smaller than the source drive for the sector-by-sector clone. What’s more, AOMEI Backuper will clone detected bad sectors as well if you use its sector-by-sector clone feature. Therefore, it’s not recommended to use this feature when there are bad sectors and you don’t need to recover data from the hard drive.

If you prefer this tool, you can follow the steps below to have a try.

Step 1: Download AOMEI Backupper Standard from its official website and install it by following the on-screen instructions.

Bonus Tip: Use MiniTool Partition Wizard as an Alternative

MiniTool Partition Wizard is another popular and reliable disk cloning software. It also includes a sector-by-sector copying method. However, different from HDD Raw Copy Tool and AOMEI Backupper, it is not an available option for users to choose manually. What does it mean?

Actually, MiniTool Partition Wizard uses two disk cloning methods: When the disk only contains partitions of NTFS and FAT file systems, only the sectors with data will be copied; if the hard drive contains other file systems that are not recognized by Windows such as Ext 2, MiniTool will do a sector-by-sector clone for them. If there are bad sectors, the sector-by-sector copy will be stopped.

Now, let’s see how to clone a disk with MiniTool Partition Wizard.

Step 1: Click the following button to download MiniTool Partition Wizard. Then install and launch it. If you want to copy the system disk, you need to upgrade to the Pro Ultimate and higher versions.
