Apple Fusion Drive Problems

A Fusion Drive is a combination of two separate hard drives. They are a mix of SSDs and Hard Disk Drives in terms of storage capacity. They can produce systems with both excellent performance and large storage capacities.

Storage on the SSD is prioritized, whereas storage on the HDD is prioritized based on how often the data is utilized. The Mac OS is capable of concurrently operating both halves of the drive. As a result, it may be used as a single storage piece. Data can be accessed fast, and it has a large storage capacity. Apple fusion drives provide up to 1 terabyte of storage for this reason.

Mac fusion drive not showing up is one of the typical Apple fusion drive problems; this article will further review methods to overcome these problems!

Why Is Fusion Drive Not Showing up on Mac?

A Fusion Drive-powered iMac and Mac mini are available now. They offer the advantages of an SSD that is fast at loading macOS and an HDD with a lot of room for your files.

However, sometimes in Files, the fusion drive may appear as two independent drives. An unreadable file system or drive failure might also cause the fusion drive's two storage units to become unavailable.

It's possible that the hard drive won't show up in Disk Utility or Storage under System Information if the SSD is in satisfactory working condition. Your Mac won't boot if the SSD isn't accessible. Following are some other common reasons why Fusion Drive is Not Showing up on Mac:

• Corrupted or formatted with an incompatible file system.
• You have not formatted the Disk Fusion Drive.
• You have an older version of the desk utility.

How to Fix Fusion Drive Not Visible Issue on Mac?

The fusion drive is responsible for storing the operating file system and user data in your Mac device, allowing the computer to function normally.

You can't access your data if the fusion drive doesn't show up on Mac, which might even cause your Mac not to start.

The following solutions can help you recover data from your Mac fusion drive.

1. Check Whether the Fusion Drive Label is Available or Not

People can acquire a fusion drive-equipped computer or other items without their awareness. Your drive is a fusion if any of the following are true:

• More storage capacity will be available compared to a single disc.
• You'll see two discs in the System Information window if you have a SATA interface.

To test whether your computer has a fusion drive, complete these procedures without opening it up: 

Step 1: Select Help from the Apple menu. Go to the Storage section by clicking on it.

Step 2: If there is a Fusion Drive labeled drive present, click OK and Close the window.

2. Fuse The Split Drives into A Single Drive

To restore the split Fusion Drive, you may either continue to use the two separate drives, or you can follow these procedures to merge them as one:

Step 1: Refresh your computer and hold Ctrl + R. Lift them when you see the Apple logo. Your computer enters macOS Recovery.

Step 2: Select Terminal > Utilities. Then Enter "Diskutil Reset Fusion" in the Command window and click Enter. Respond with "Yes" and hit Enter.

Step 3: Exit the Terminal. Uninstall the macOS and press Continue. Then re-install macOS as directed. Your computer restarts the fusion drive as a single drive.

3. Repair Fusion Drive Corruption with First Aid

Use the First Aid option to resolve problems with your hard disc drive.  The storage drive’s fundamental structure may be reviewed and repaired by following these easy steps:

Step 1: Start by turning on your Mac and pressing Command + S until white writing shows on the computer. Single-User Mode will be activated upon startup.

Step 2: Enter "fsck –fy" into the command line and press Enter. To prevent data loss, do not interrupt until the instruction is complete.

Step 3: Repeat the same command if you get the notice "The volume Macintosh HD could not be repaired."

Step 4: Repeat the procedure until "The volume Macintosh HD seems to be OK" displays. Then restart your Mac by typing exit.

4. Format Fusion Drive to A Compatible File System

Windows File Explorer won't see a Mac-based storage disc connected to a Windows PC. The incompatibility of data files is the root cause of this problem's occurrence. Only Mac OS X may access the hard drive's APFS or HFS+ file systems. Follow these steps to resolve the issue:

Step 1: Make a complete backup of the storage drive’s contents using an operating system suitable for the drive.

Step 2: Choose the FAT32 data file format to format the disc. (Alternatively, you may format a USB device in FAT32, which has a maximum file size of 4 GB.)

Step 3: The backed-up data should be restored to the storage media.
