What is External Hard Drive Formatting Process?

Formatting external hard drives is a process of deleting or erasing the memory chunks to avail the space for new data. Formatting can be performed at two stages: low level and high-level process. Formatting may take a few hours to wipe out the existing data, but the process can be hassle-free if you get to know about stepwise instructions on how to format an external hard drive.

Low-level formatting is the first process of wiping out data and existing files in the hard disk devices and at the high level, a new file system is generated. Technically, it is the process of writing a new directory structure that allows the documents and files to be overwritten and create space for the new data.

Before formatting external hard drives, backup all important data that you are going to format. Most external hard devices come with backup software that will make the process much easier to do. If you have documents, music, photos saved elsewhere on the computer then make sure you have copied all stuff before formatting. Remember once all the data get formatted, it will not be recovered at any cost.

File System Explained:

Before proceeding to format the external hard drive, you need to know about file systems that are particularly associated with the operating systems. File systems are the key parts of translation from the physical data recording on a hard drive to the files that are read by operating systems only.

Various operating systems like Mac, Windows, Linux, and OS X have different file systems to organize and store digital information. The most popular file systems are as discussed below:

  • NTFS (New Technology File System): NTFS is developed by Microsoft, started with Windows NT 3.0. It is also known as Window's default file system. Microsoft has launched five versions of NTFS: v1.0 released with Windows NT 3.1, v1.2 with Windows 3.51, v3.0 with Windows 2000, v3.1, and v5.0 with Windows XP. The latest version includes many features like disk usage quotas, link tracking distribution, reparse points, file-level encryption, and sparse file support. Windows can write and read to NTFS formatted hard drives while OS X and Linux can read-only but can't write unless it is supported by third party devices like NTFS-3G. It has a maximum of 16 TB file size and 256 TB volume size.
  • FAT 32 (File Allocated Table): It was designed in the year 1977 for floppy disks and three major file systems variants are: FAT12, FAT16, and FAT 32. The older version of FAT was quite simple and robust. FAT32 has come up with the increased number of bits which is used to address clusters. It also helps to reduce each cluster size due to which it will have great storage capacity and effectively support the large disks up to 2 TB. It can be written and read by Linux, OS X, and Windows. FAT32 offers a maximum of 4GB file size and 2 TB volume size.
  • ExFAT (Extended File Allocated Table): It is quite similar to FAT32 and is less commonly used. ExFAT can store up to 4GB files which make it perfect for flash drives. ExFat formatted drives can be read and written by OS X and Windows.
  • HFS Plus (Hierarchical File System): It is developed by Apple Inc. It serves as the primary file system of OS X and also known as Mac OS Extended. For those who are operating Windows on Mac with Boot Camp, they can read HFS plus hard drives but can't write to them. However, third-party tools like Paragon HFS+ assist the users to write and read to HFS+ drives. HFS plus offers 8 EiB maximum file size and volume size.

These are the popular file systems for Windows, Mac, and Linux operating systems. For those who are running Windows computers, they can format hard drive as NTFS, and for the Mac users; ExFAT will be the best and reliable option.
