Windows Cannot Run Disk Checking On This Volume Because It Is Write Protected

As soon as Windows 10 started this morning, I got a message saying that Windows had identified a hard disc issue. Since I figured it was the newly attached external backup drive, I ran a check for hard drive issues after doing a little research online. To my dismay, I discovered that the drive was write-protected after typing chkdsk F: /f at the CMD command prompt.

The file system type is NTFS, according to the message. Because this volume is write-protected, Windows is unable to perform disc checking on it. For some reason, I cannot recall if I enabled write protection. How can I successfully run CHKDSK on a write-protected device after removing the write protection on my external hard drive?
