In most cases, the majority of people would be lost when they encountered trouble of not being to read or write data as they used to. So, a comprehensive tutorial about how to change read/write permission on a flash disk/memory card becomes urgent.

Altogether, this guide offers three ways to obtain or deny the read/write permission on HDD, SSD or a removable storage media.

First, there's a slide switch on most of the memory cards and flash drives

Take out your object that doesn't allow you to make any change on it, and carefully examine it. Is there a little tiny slide switch that points to a Lock position downwards? This switch is designed to avoid accidentally deleting photos or unwanted access to the inside data. So, when you found yourself being blocked, turn the switch to the opposite direction of the Lock position, aka Unlock.
