Real user case

“Hi, my old 1TB Seagate external hard drive has been working for many years and its performance cannnot meet my requirements any longer, so i am planning to resell it and buy a new 2TB external hard drive. But i have stored a large number of data on the hard drive, so i want firstly to clean all the existing and history data on this Seagate external hard drive. Can I just format it? Or I need to totally wipe Seagate external hard drive? Thanks in advance."

Format or Wipe, which is better?

Formatting or wiping external hard drive depends on your specific requirements. If you are in the same situation as the user above, you need to wipe it instead of just formatting it via a disk formatting utility. That’s because formatting process just makes the data invisible to the operating system, but they are still there, and can be recovered by some data recovery software. Then your private data including financial and business information will expose. That's danagerous, right? So if you plan to donate, resell or throw away the Seagate external hard drive, you need to completely wipe it to prevent personal data leakage.
