How to Change External Drive from Read-Only or Write-Protect to Read Write Mode?

Guide on How to Remove Read-only or Write Protection from External Drives

Every computer user has, at some point, encountered a frustrating situation where an external drive refuses to allow data modifications. The culprit behind this restriction is the ‘Read-only’ or ‘Write-protected’ status of the drive. Essentially, when a drive is set to read-only, users can view and access the data stored, but they cannot make any changes to it. Such a setting can be quite beneficial when one wants to secure the contents of a drive from accidental deletions or unwanted edits. Often, users might find their external HDD, SD memory cards, or USB flash drives inadvertently stuck in this mode. If you’ve faced such a challenge and are scratching your head, wondering how to revert the disk back to a state where you can both read from and write to it, you’re in luck. In this guide, we will detail various methods, ranging from simple property modifications to using specialized software, to change your external drive from read-only to read-write mode. So, let’s dive in and explore how you can regain complete control over your data.
