To protect everything on your hard drive, you may consider bit-by-bit copy. Get the best free bit copy software in this article.

What is bit-by-bit copy?

Bit-by-bit copy means to copy all areas of a computer hard drive or other storage devices. It replicates all sectors including blank sectors and logically bad sectors, so it is also called sector-by-sector clone. The data stored on the cloned drive is identical to the data on the original drive.

As a result, you can upgrade your old hard drive to a larger one without reinstalling the operating system and all your applications. Besides, if there are defective areas on your old hard drive, a recovery procedure on the disk will cause further defects because of the inherent exposure of the procedure while cloning disk bit by bit causes much less exposure due to its linear operation. You can replace the damaged hard drive with the cloned one without losing data.

Since bit-by-bit copy is useful, how can you complete the task?

Why do you need bit copy software?

As Microsoft hasn’t ever included a tool for making an exact copy of a hard drive in Windows, what you need is a reliable bit copy software to achieve the goal of bit-by-bit copy. Cloning disk sector by sector requires the logical sector size of the source and target disks to be same, or the clone process will fail. Therefore, you should choose a bit copy software that is smart enough to skip blank clusters and is capable of cloning between disks in different logical sector sizes. Which bit copy software can meet the demand?

  • Sector-by-sector clone will copy every sector on the source disk no matter it is used or not, so the destination disk must be equal to or larger than the source disk.

  • The destination disk will be completely overwritten. Backup the destination disk before you start clone if there are important data on it.
