LaCie Hard Drive is Read-Only on Mac Computers – What to Do?
LaCie makes good-quality external hard drives with cool designs. It's owned by Seagate and is popular among creative professionals, photographers, and people who need lots of reliable storage. They have different types of drives, like portable ones and big ones, and they work with both Mac and Windows. LaCie's drives look unique, are sturdy, and can connect in different ways, making them great for saving data, storing stuff, making content, and watching videos.
Why is your LaCie hard drive read-only on your Mac? Usually, you can both read from and write to your LaCie drive on your Mac. However, there are instances where you might find that you can only read from it. Let's briefly explore some potential reasons for this issue:
1). The LaCie hard drive is formatted with a Microsoft NTFS file system, which can limit write access on macOS.
2). You may lack the necessary permissions to write to the LaCie hard drive, leading to read-only access.
3). Tiny disk errors on the LaCie hard drive might be causing this restriction.
Understanding these reasons can help you address the read-only issue with your LaCie drive on your Mac.
Scenario 1: Your LaCie Hard Drive is in NTFS Format
The Mac operating system does not fully support the Microsoft NTFS file system due to copyright constraints. This means that while you can read data from an NTFS-formatted LaCie hard drive on your Mac, you cannot write data to it. Therefore, if you find your LaCie hard drive is read-only on your Mac, it's a good idea to check its file system first.
How to Determine the File System of Your Hard Drive:
Here are the steps to check the file system of your LaCie hard drive:
- Connect your LaCie drive to your Mac and open the Disk Utility app.
2. In the Disk Utility window, select your LaCie drive from the left sidebar.
3. You can now view the file system of your LaCie hard drive.
4. Checking if the LaCie Drive is NTFS Formatted:
Click on the "Info" tab located in the upper right corner of the Disk Utility window to see if the LaCie drive is writable on your Mac.
If you discover that your LaCie hard drive is indeed NTFS formatted and you are facing the read-only issue on your Mac, you can try the following steps to resolve it.
Solution. Utilize NTFS Software for Mac to Address the Read-Only Issue
Converting NTFS to APFS, HFS+, HFS, or FAT file systems can be a cumbersome and time-consuming process, as it requires creating a full backup of the data on your LaCie drive.
Alternatively, you can employ NTFS software designed for Mac to enable write support for your LaCie drive. We highly recommend using iBoysoft NTFS for Mac, which allows seamless reading and writing to NTFS-formatted hard drives on your Mac.
Follow these steps to write to your LaCie NTFS drive on your Mac:
- Download and install "iBoysoft NTFS for Mac" on your device.
2. Connect your LaCie drive to your Mac and launch "iBoysoft NTFS for Mac."
3. After the external hard drive is successfully mounted in read-write mode, you can write data to the NTFS external hard drive without any issues.

Scenario 2: The LaCie Hard Drive has Read-Only Permission Issue
The ability to read and modify files on your device is determined by permission settings. In this section, we'll explore two solutions to change the read-only permission of your LaCie hard drive.
2.1 Modifying Read-Only Permission on Mac with Admin Privileges
Follow these steps to adjust permissions on your Mac using your admin account privileges:
1. Right-click on your LaCie drive and select the "Get Info" option.
2. Locate the "Sharing & Permissions" tab and click the triangle icon to expand it.
3. Click on the padlock icon and provide your account password when prompted.
4. Next to the user account, which currently has "Read only" permission, click it and change it to "Read & Write."
5. To apply this change to all enclosed items, click the up and down arrows, and then click "OK" to save your modifications.
After completing these steps, you can check whether you can now write to your LaCie drive. If the issue persists, proceed to the following solution.
2.2 Ignore the Permissions on an External Hard Drive
macOS offers a feature that allows users to disregard permission settings on external drives, enabling full write access to files and data regardless of permission restrictions.
1. Right-click your LaCie drive icon on the Mac desktop and select the "Get Info" option.
2. Scroll down to locate the "Sharing & Permissions" tab, then click the padlock icon and enter your user password.
3. Enable the "Ignore ownership on this volume" option.
4. Click the lock icon to save these changes.
By implementing these steps, you can effectively address the read-only permission issue and have the ability to write files and data to your LaCie drive without restrictions.
Scenario 3: LaCie Hard Drive has Minor Disk Errors
If the previously mentioned reasons are not responsible for your LaCie drive being read-only on your Mac, it's likely that your LaCie drive has encountered minor disk errors. Typically, you'll notice this when your LaCie drive is mounted in read-only mode within Disk Utility.
In this situation, you can try running First Aid to repair the disk on your Mac or consider reformatting your LaCie drive for future use.
3.1: Running First Aid to Address LaCie Read-Only Issue on Mac
macOS includes a feature called First Aid in Disk Utility, designed to identify and repair minor disk errors. Follow these steps to utilize First Aid:
1. Launch Disk Utility on your Mac.
2. Select your read-only LaCie external hard drive from the left sidebar.
3. Click on "First Aid" and choose "Run" to initiate the disk repair process.
After Disk Utility completes the First Aid operation, check if you can now write to your LaCie drive on your Mac. If the issue persists, you may need to consider reformatting the drive to a Mac-compatible file system.
3.2: Reformatting Your LaCie Drive for Future Use
Before proceeding with the formatting process, ensure that you have created a comprehensive backup of all the data on your LaCie drive, as formatting will erase all existing data.
Here's how to reformat your LaCie drive:
1. Connect the NTFS-formatted drive to your Mac.
2. Navigate to your Mac's Home Folder, locate "Applications," and open "Disk Utility."
3. In the Disk Utility window, select the NTFS drive.
4. Click on the "Erase" option in the toolbar.
5. Provide a name for your drive.
6. Choose "APFS" as the format and select "GUID Partition Map" as the Scheme. Alternatively, you can opt for "ExFAT" if you intend to use the drive on both Mac and Windows systems.
7. Click the "Erase" button to initiate the reformatting process.
Once the reformatting is complete, your LaCie drive will be in APFS format, allowing you to write to it freely on your Mac.
In short, the read-only status of your external hard drive on a Mac is the result of an incompatible file system with macOS, the read-only permission settings of your drive, and some disk errors on your LaCie drive. To resolve this issue, you can install the NTFS for Mac driver, adjust the permission settings, and run First Aid.
