Is your USB drive showing "read-only" on Mac? Let's help you fix that.

Mac devices are known for their great products. Not only are they employed by people in various facets of life, but their demands have also gone up in recent times because of the pandemic and the entire work-from-home scenario. However, one common problem a lot of Mac users run into is low storage.

That's why they use USB drives to back up their data or move important files. However, one common problem that many Mac users face is their USB devices being read-only. This annoying problem can become difficult to deal with.

So, how do you fix it when your USB drive is read-only? Let's dive in and find out.

Can Macs Read and Write FAT32?

The first step in understanding if the USB drive read-only Mac Fat32 can be fixed. Now, the thing with specific formats is that some are only Windows compatible, while others only work with Mac computers. Now, FAT32 is the only file system that's supported by both.

Shortened from File Allocation Table 32, FAT32 has been around since 1977. Therefore, both Mac and Windows computers support it and run it seamlessly. You can read and write using this file system on both operating systems. Some key information about FAT32 includes:

  • 2TB is the max storage supported by this file system.
  • Doesn't support transparent encryption.

However, once you connect a FAT32 USB to a Mac device, it tends to turn it into a read-only state. This permission is altered by Mac as soon as it reads the file system after detecting the external storage.

Check Whether USB Is Running Well

Finding out the problem with your USB drive read-only Mac FAT32 device is your first task. It might just be that your device isn't performing well, so the Mac renders it read-only since it cannot access specific parts of your storage.

Here's how you can check that on a Mac computer:

Step 1. Go to Finder, then Applications, and run Disk Utility.

Step 2. From the sidebar, pick the USB device you wish to check.

Step 3. Then run First Aid.

Step 4. Click on Run when prompted.

If your USB device is working well, then you'll see something like this:

So, how do you check whether the USB is running well in Windows? Here's how:

Step 1. Press Windows+R and type CMD.

Step 2. Type chkdsk H:/f.

Once the check is done, and you see something like this, then your USB device is working well. How? On the lower side of the screen, look at "0 KB in bad sectors". As it indicates the error-free performance of our device.

How to Unlock USB Drive That Is Read-Only Mac (FAT32)?

Now that you've determined your USB device is working find out how do you unlock a USB drive that's read-only on Mac FAT32? There are three main methods that you can use, such as:

  • Change or bypass permissions and access the device to change read-only settings.
