Erase a Seagate Drive
Need to erase a Seagate drive instead of simply delete or format backup files stored in it? ByebyeData Eraser would like to help. First we'd like to make two guides on erasing a Seagate hard drive, that's to erase an internal hard drive and an external hard drive. To be more specific, erase internal Seagate system disk, erase internal Seagate secondary disk and erase external Seagate hard drive.
Erase system disk is somewhat different from non-system disk erasing, so we'd like to explain the non-system disk earing first, which applies to internal secondary hard drive and external hard drive erasing, for Seagate or other hard drive companies.
1 Backup all the essentials to another disk or external hard drive, or connect Seagate hard drive and backup files to local disks. Don't ignore this step if data in the drive is important.
2 Download ByebyeData eraser, install the program and run it, click Yes to the UAC dialog (User Account Control).
3In the main window, click the Erase disk tab and all the wiping methods are listed in the tab, in the list area you can see all the disks you connected to the computer, Find the Seagate internal/external hard drive and click it.
4Select an erasing plan for the hard drive from the security column in simple, advanced, complex and very complex section. As you may know, 1-3 passes are fast and efficient ways of secure erasing data. If you're erasing 1TB and above capacity Seagate hard drive, 7 passes overwrite method will take really longer time, and 35 passes will take even much longer than that, maybe days or a week.
5Click Erase Now and confirm the step when the popup message shows.
That's all the steps to erase Seagate hard drive, no Windows system included, since we need to erase the system drive in a bootable media, So if you're about to erase everything on the Seagate hard drive, a bootable CD/DVD/USB is required.
In ByebyeData Eraser, click Bootable media first and follow the bootable media guide to create the ISO file and burn it your media, CD/DVD is easy to burn and it requires no third-party software in Windows 7 and Windows 10, but for bootable USB burning, it is better to download Rufus and burn ByebyeData Eraser to USB with it.
After the bootable media is created, we need to quit all the running programs and reboot the computer > boot from CD/USB > click Erase disk in ByebyeData Eraser and repeat the above steps of erasing external Seagate hard drive.
