When using a Mac, you may encounter situations where your hard drive is set to read-only mode, preventing you from making any changes or modifications to its contents. This can be frustrating, especially if you need to edit or delete files on the drive. Fortunately, there are steps you can follow to change your hard drive from read-only mode without having to erase any data. In this tutorial, we will guide you through the process.
Step 1: Open a Terminal window by clicking on the magnifying glass icon in the top-right corner of your screen, typing "Terminal," and selecting the "Terminal" app from the search results.
Step 2: In the Terminal window, type the following command and press Enter: sudo nano /etc/fstab
Step 3: You will be prompted to enter your administrator password. Type the password and press Enter. Note that when typing your password, you won’t see any characters on the screen. This is normal security behavior.
Step 4: The Nano text editor will open, displaying the contents of the ‘/etc/fstab’ file. Scroll down using the arrow keys until you find the line that starts with "UUID=". This line represents your hard drive.
Step 5: Move the cursor to the end of the line and add a space followed by "rw". The line should now look like this: "UUID=XXXXXXXXXX none ntfs rw", where "XXXXXXXXXX" represents the UUID of your hard drive.
Step 6: Press Ctrl+O to save the changes to the ‘/etc/fstab’ file. Press Enter to confirm the filename, and then press Ctrl+X to exit the Nano text editor.
Step 7: Restart your Mac to apply the changes. After the restart, your hard drive should no longer be in read-only mode, allowing you to modify its contents.

How do I permanently turn off read only?
If you want to permanently turn off the Read Only attribute on a file or folder, there are a couple of steps you can follow. Here’s a professional guide to achieving this:
1. Access the Properties of the file or folder: Right-click on the file or folder you want to modify and select "Properties" from the context menu.
2. Remove the Read Only attribute: In the Properties window, you will see the attributes of the file or folder. If the Read Only attribute checkbox is checked, click on it to remove the checkmark. This action will remove the Read Only attribute from the file or folder.
3. Apply changes to subfolders and files: If you wish to apply the changes to all subfolders and files within the folder, navigate to the "Advanced" button in the Properties window. Click on it, and a new window will open. In this window, check the box that says "Replace all child object permission entries with inheritable permission entries from this object" and click "OK" to confirm.
4. Confirm changes: After applying the changes, return to the Properties window and click "OK" to save the modifications you made.
At this point, the Read Only attribute should be permanently turned off for the selected file or folder, along with its subfolders and files if you applied the changes to them. However, keep in mind that some system files and folders may have the Read Only attribute set for security reasons, and modifying them may cause unforeseen issues. It’s advisable to exercise caution when altering properties for system-related files and folders.
Please note that these instructions are based on a Windows operating system; the process might differ slightly if you’re using a different operating system.
How do I change my hard drive from read only to write?
To change your hard drive from read-only to write, you can follow these steps:
1. Check the physical read-only switch: Some external hard drives or USB drives have a physical switch that allows you to toggle between read-only and read-write mode. Ensure that the switch is in the correct position for write access.
2. Adjust the file/folder permissions: If the read-only status is specific to certain files or folders, you can modify the permissions to enable write access. Right-click on the file or folder, select "Properties," go to the "Security" tab, click on "Edit," and grant yourself the necessary write permissions.
3. Check the drive properties: For some cases, the drive itself might have incorrect settings that make it read-only. To change this, right-click on the drive, select "Properties," go to the "General" tab, and ensure that the "Read-only" checkbox is unchecked. If it’s checked, unmark it and click "Apply."
4. Use Command Prompt or Terminal: If the above steps don’t solve the issue, you can try using Command Prompt (Windows) or Terminal (Mac) to change the attributes of the drive. Open the respective utility, type the command "diskpart" on Windows or "sudo" on Mac, then enter the appropriate commands to select the drive and remove the read-only attribute. The specific commands may vary depending on your operating system and drive configuration, so it’s important to follow a guide or consult professional assistance if you’re unfamiliar with the process.
5. Disable write protection in the Registry (Windows): In some instances, specific registry settings may be causing the read-only status. To address this, open the Registry Editor by pressing Windows Key + R, typing "regedit," and hitting Enter. Navigate to the following path: "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies." Look for a key named "WriteProtect" and ensure its value is set to "0". If it’s set to "1", double-click on it and change the value. Restart your computer for the changes to take effect.
Remember to be cautious when making changes to your system settings and always back up your important data before attempting any modifications. If you’re unsure or uncomfortable with any of the steps, it’s advisable to seek professional assistance.
