Nowadays, it's impossible to imagine storing and transferring massive amounts of data without an external hard disk. When it comes to external storage options, LaCie is a well-known brand that provides drives that are both dependable and fast.

Yet, users may occasionally have a problem where their LaCie external hard drive becomes read-only on a Mac, which hinders their ability to edit or upload data. You shouldn't worry; you can take several troubleshooting steps to fix this annoying problem and get complete access to your LaCie external hard drive again.

Why is LaCie hard drive read-only on Mac?

Permission Settings:

Getting read-only access to the LaCie disk is possible due to improper or limited permission settings. You can't let users edit or add files to a drive if the permissions are set to read/write solely.

File System Errors:

The external device can be mounted in read-only mode to avoid data corruption caused by file system failures or inconsistencies. Possible causes of these problems include improper ejection, unexpected power outages, or drive damage.

Compatibility Issues:

Suppose your Mac and LaCie external drive isn't compatible. In that case, you may only access the drive in read-only mode: the macOS version, incompatibility with other file systems, or out-of-date drivers.

Disk Corruption or Damage:

The inability to access data from an external hard drive might also be caused by disk corruption or physical damage.

Software Glitches or Bugs:

The external drive might mount as read-only due to a Mac OS X or LaCie particular software malfunction.

Journaling or Metadata Issues:

When the journaling feature - meant to record file system changes—hits a snag, the drive could go into read-only mode to avoid corruption or data loss.

If the LaCie external hard drive is a NTFS drive and you don’t want to format it, you can try third-party NTFS for Mac tool to enable NTFS read-write on your Mac. It is very simple:

Step 1. Download and install a NTFS for Mac tool - DoYourData NTFS for Mac on your Mac and connect the LaCie external hard drive to your Mac.

Step 2. Open DoYourData NTFS for Mac, click NTFS disk, then choose the LaCie external hard drive.

To begin, check that your LaCie external drive's permissions are configured correctly:

Go to the LaCie drive icon, right-click, and choose "Get Info."

Find the "Sharing & Permissions" section and check that your user account has "Read & Write" rights. If it isn't already, go to the settings, enter your password, and then click the lock symbol.

Fix 3. Using Disk Utility for Repair

To resolve disk-related problems, you can use Disk Utility, a built-in macOS tool:

After finishing, try reconnecting the drive to see if the problem still exists.

Fix 4. Resetting NVRAM/PRAM

Certain system-related difficulties can be resolved by resetting Non-Volatile Random-Access Memory (NVRAM) or Parameter RAM (PRAM):

Turn off your Mac and turn it back on again.

When you hear the startup sound twice, press and hold the Option, Command, P, and R keys simultaneously.

When the Mac is ready to start up normally, let go of the keys.

Fix 5. Updating Software

Issues with read-only functionality could arise from incompatible drivers or outdated system software:

Look in the Mac App Store for any new macOS versions.

Fix 7. Terminal Commands

To modify the permissions of a drive, advanced users can use the Terminal commands:

Navigate to Applications > Utilities > Terminal to launch the Terminal.

To change the flags for your LaCie drive, run the following command: sudo chflags -R nouchg /Volumes/YourDriveName, where "YourDriveName" is the name of your drive.

Fix 8. Backup and Reformat

Think about creating a backup and reformatting the drive if everything else fails:

Launch Disk Utility and choose the LaCie drive.

For example, you can choose "Erase" and then choose "FAT32," "macOS Extended," or exFAT as your file system format.

Make sure that the drive is working properly before transferring any further data.

Conclusion:

To sum up, it's not fun when your LaCie external hard drive becomes read-only on a Mac, but luckily, there are a few ways to fix it.
