Overview of the Read/Write Permission on a Flash Disk/Memory Card
As you can figure out by yourself, there are read and write permissions on a hard disk drive, memory card, USB stick, pen drive, and jump drive. To gain full access to a drive and data within, or take further control, for example, copy, edit and delete files, partition, and format the disk, you must be authorized to use the storage with both read and write permissions. 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.
Fix 1. Change Permission by Turning Off the Slide Switch
And, here is the first solution. Some USB flash drives or memory cards have a physical switch. If the switch is turned on, it needs to be closed to solve it.
To switch off the memory card physical switch:
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.
What if the Lock and Unlock switch is broken? Do your best to recover data from a locked SD card.
To switch off USB flash drive physical switch:
Not all the flash drive has the lock switch. So, you should check first. Take out your USB, if there is a physical lock switch on the side, then slide the switch to the unlock area.
Fix 2. Manually Set Drive Security Permissions
Nevertheless, quite a lot of removable storage devices are not coming with the Lock switch, what's the matter? Where to change the read/write permission? At this moment, you need to get about the task on a computer.
Step 1. Correctly insert your USB stick or SD Card to the computer, and make sure Windows has detected it.
Step 2. In Windows 10, 8 or 7, press "Windows + E" simultaneously to open File Explorer.
Step 3. Locate the drive letter that presents your device. Right-click on it, and select "Properties".
Step 4. Navigate to the Security tab, in the middle of the Properties window; you'll see 'To change permissions, click Edit'. This is where you can change read/write permission on the target disk. So, click "Edit", and the Security window immediately pops out.
Step 5. Here, you'll find "Permissions for Authenticated Users" with either an "Allow" or "Deny" option. By checking the Deny boxes next to the permissions like Full Control, Modify, Read and Write, you're setting the drive and its contents to read-only. Otherwise, to disable the read-only attribute, check the Allow boxes. Click "Apply".
Step 6. Click "OK". You should now do a successful change in the read/write permissions.
Fix 3. Remove Write Protection from a USB Stick or Memory Card Using CMD
In the event that Windows fails to format a disk with error messages like "the disk is write protected", you have to remove write protection with some advanced measures.
Step 1. Press "Windows + R" simultaneously, type cmd and run administrative "Command Prompt".
Step 2. Type the following command lines and hit Enter after each command line.
select disk #
attributes disk clear readonly
# is the number of the write-protected flash drive or memory card.
Step 3. Exit the Command Prompt.
