Is it necessary to wipe Seagate external hard drive?

A portable device like Seagate external hard drive may have stored your identification, commercial documents, receipts, photos, resume, etc. Once you decide to resell or give it away, erasing the privacy information becomes an essential step. But are your deletion means really safe?

As a matter of fact, the data you delete via right-click menu or a shortcut is just marked as “deleted”. Anyone who gets the device can still recover these files by specific software. Therefore, you must take more robust initiatives to erase Seagate external hard drive.

How to erase Seagate external hard drive with built-in tools?

After ruling out the manual deletion method, many people might think of formatting - is it an effective solution?

In practice, most of people would perform a quick format to make the formatting process faster. But data deleted in this way will remain on the hard drive until it’s completely overwritten.

For better security, you need to reformat Seagate external hard drive in full mode, which overwrites zeros and ones over the data, i.e. write zero to hard drive. Similarly, you can use the “clean all” command of DiskPart to wipe a hard drive with zero-filling. This will undoubtedly make the data more difficult to recover (but not impossible).

Note: To avoid unwanted data loss, please backup external hard drive before formatting.

Full format way:

  • Right click a drive in File Explorer and choose Format
  • Choose a file system and uncheck Quick Format
  • Click Start to proceed.

*A full format will take longer time, depending on your drive size.

*You can use this way to wipe an external hard drive, but not a system drive.

DiskPart way:

  • Search for “Command Prompt” and run it as administrator
  • Type “diskpart” and press Enter
  • Type “list disk” and press Enter
  • Type “sel disk x” and press Enter (x refers to the serial number of the disk)
  • Type “clean all” to wipe the Seagate external hard drive.

The two methods may be enough for ordinary cases, but if you’ve stored some sensitive information in the external hard drive, you may need more reliable wiping methods.

More secure way to wipe Seagate external hard drive on Windows

In fact, there’s a function called Seagate Instant Secure Erase (ISE) integrated in SeaTools. It resets the drive to factory settings and change the encryption key to permanently erase the data remaining on Seagate hard drive. However, it only works on Windows 8 or earlier OS, and the operation is kind of complicated.

Therefore, I’d like to introduce the Disk Wipe feature of AOMEI Backupper for secure erasing and simple operation.

First of all, AOMEI is a comprehensive data protection tool works on Windows 10/8.1/8/7/Vista/XP. You can use it to wipe HDD/external hard drive/USB drive regardless of brands.

It’s a one-stop solution to backup important files of the Seagate external hard drive and then wipe it. Also, it erases the hard drive faster than the Windows built-in formatting.

And AOMEI Backupper Professional includes 4 options in total to wipe Seagate external hard drive securely, they are:
