External hard drives, such as those made by Seagate, provide a way to back up important data and media stored on your computer. However, there isn't much point in storing all of this data if you can't access it. That's what happens when a hard drive is set to "read only" mode. That means you can look at the information stored on the drive, but you can't add or remove data. The good news is you can change your Seagate hard drive from "read only" without the help of a service technician. All you need to do to is reformat the hard drive.
