Formatting the External Hard Drive: Will it Erase Everything?

Most of us have gone through the process of formatting the external hard drive from time to time. There are mainly two purposes of formatting an external hard drive, viz., freeing up space, and changing the file system format of the drive. Other issues that may be fixed by formatting the external hard drive are a corruption of files, bad sectors in the drive, etc. However, many users ask that if I format my external hard drive will it delete everything. They actually want to know whether there are chances of recovering the data after an external hard drive has been formatted. The generic answer is ‘Yes’, but we need to understand the extent to which recovery is possible and the remedy to this problem.

We have discussed the process of formatting and solution to permanently erase data from an external hard drive easily in this article. So, why wait? Let us begin.

Formatting an External Hard Drive

Let us first try to understand what happens if I format my external hard drive. Will it really delete everything, or is it going to erase everything on my hard drive? It would be best if you understood that while delete and erase might appear to be synonyms, they are actually two different processes in the world of Information Technology. Formatting an external hard drive or any other storage device using Windows File Explorer or Disk Management or Format command frees the space and prepares it for specific use. Following are the things that happen on formatting the drive:

  • It deletes all the data saved on the external hard drive.
  • It allows resetting the file system to NTFS, exFAT, FAT 32, etc.
  • Free the drive from some basic threats of viruses, malware, etc.

It should be understood that formatting the hard drive does not erase the data. Rather, it deletes the data so that its recovery becomes difficult compared to deletion by delete button or Shift + Delete command. Although a professional data recovery software like Stellar Data Recovery can still extract or recover most of the formatted data.

Erasing Data on External Drive

Erasing data on an external hard drive ensures that there is no possibility of data recovery, even by using professional data recovery software. Data on a hard drive is permanently erased using professional data eraser software. A data eraser software uses secure algorithms to overwrite the existing or deleted data with binary digits or random useless data multiple times, thus rendering the actual data irrecoverable. Therefore, it safeguards your personal data from falling into the wrong hands and being misused.
