Introduction

USB drives are essential tools for data storage and transfer, but encountering a read-only state can be frustrating. This comprehensive guide aims to help you easily remove the “read only” state from a USB drive on PC, ensuring you can use it effectively without hindrance.

Understanding the Read-Only State

The read-only state prevents users from modifying or deleting files on the USB drive. This can be a protective feature to secure important data, but it can also lead to inconveniences when you need to edit or remove files.

What Does Read-Only Mean?

When a USB drive is in a read-only state, it means that the operating system has restricted write permissions. This can happen due to various factors including physical write protection switches, system settings, or file corruption.

Common Causes of Read-Only State

• Physical write protection switch is enabled
• File system errors on the USB drive
• Corrupted files or partitions
• Operating system settings or restrictions
• Malware infections that alter file permissions
