To make a byte-for-byte copy of a drive, DD does an excellent job for the most part. All you need to do is specify the input and output:

DD if=/dev/hdb of=/image.img

However, there are a few drawbacks to using DD.

  • DD will copy your entire disk, even empty space. Therefore, it may result in an extremely large image file, even larger than the original disk.
  • The copy takes a long time but DD provides no progress indication.

Therefore, you may want to try some new ways to copy your drive. You may use EaseUS Disk Copy to make a byte-for-byte copy of a drive.
