1. Open Disk Utility by navigating to Utilities via Applications.
2. In the left-hand sidebar, find the external drive that's causing the issue.
3. Select the drive and click the First Aid button at the top.

4. Disk Utility will run a series of diagnostics and attempt to repair any detected issues.
5. Once completed, try mounting the drive again.

What to Do if First Aid Fails:

If First Aid reports that it can't repair the drive, the problem may be more severe, and you'll need to move on to more advanced solutions, such as using Terminal or reformatting the drive.

Fix 3: Check and Repair the Disk Using Terminal

If Disk Utility is unable to resolve the error, you can use Terminal to perform more in-depth disk repairs. Terminal allows you to execute commands that can sometimes fix issues Disk Utility cannot.

Steps to Repair the Disk Using Terminal:

1. Identify the Disk:

To begin, you need to identify the disk that is causing the issue.

1. Open Terminal (located in Utilities under Applications).
2. Type the following command and press Enter:

   diskutil list

   This will list all connected drives and partitions. Identify the external drive by its size or name.

2. Repair the Disk:

Once you have identified the disk, use the following command to repair it:

diskutil repairDisk /dev/diskX

Replace diskX with the correct disk identifier (e.g., disk4). Type y and press enter.

3. Use the fsck Command (if needed):

If diskutil repairDisk doesn't resolve the issue, you can try the fsck command, which performs a file system consistency check.

1. Type the following command and press Enter:

   sudo fsck_hfs -fy /dev/diskX

   Replace diskX with the disk identifier again.

After the repair process, try mounting the drive again and see if the error persists.

Fix 4: Use NTFS for Mac tool

If the external hard drive is an NTFS drive, you can use NTFS for Mac tool to solve this problem.

Step 1. Download and install the reliable NTFS for Mac tool - Donemax NTFS for Mac tool on your Mac.

Step 2. Open Donemax NTFS for Mac, select the NTFS drive, click on Enable Writable button, then you can read-write the NTFS drive without any limitation.

Step 3. Click on Mount button to mount the NTFS drive on your Mac.

Fix 5: Reformat the Drive (as a Last Resort)

If the above steps don't work, reformatting the drive may be the only way to resolve the issue. However, reformatting the drive will erase all data, so proceed with caution.

Backing Up Data Before Reformatting:

If possible, use data recovery tools to back up important files from the drive before reformatting. Several third-party applications allow you to recover data from corrupted drives. This step is especially important if you have valuable data stored on the drive.

Steps to Reformat the Drive:

1. Open Disk Utility.
