Apple Fusion Drive Issues

Fusion Drive is a storage solution that combines two separate hard drives. It merges the attributes of a Solid State Drive (SSD) and a Hard Disk Drive (HDD) for storage. This drive offers a system with both high performance and large storage capacity.

Hard Drive Wars: Fusion Drive vs SSD vs HDD – Which Is Better?

You might think that a hard drive is a hard drive, but that's far from the truth. In reality, there are several different types of hard drives...

Storage on the SSD is prioritized, while storage on the HDD is prioritized based on how frequently data is accessed. The Mac OS manages both parts of the drive as a single storage device, allowing for quick access to data and plenty of storage space. For this reason, Fusion Drives can offer up to 1 terabyte of storage.

"Mac Fusion Drive Not Showing" is one of the common issues with Apple's Fusion Drive. This article delves into the methods to resolve these problems!

Why doesn't Fusion Drive show up on my Mac?

The iMac and Mac mini with Fusion Drive are available now, offering the fast startup times of an SSD and the high storage capacity of an HDD.

However, in the Files app, a Fusion drive might appear as two separate volumes. If the file system is unreadable or there's a disk failure, both storage units of a Fusion drive might become unavailable.

If the SSD is functioning properly, it might not appear under Storage in Disk Utility or System Information. If the SSD isn't accessible, your Mac won't start up. Here are some common reasons why a Fusion Drive might not appear on your Mac:

• The disk was damaged or reformatted with an incompatible file system. • You didn't format the Fusion drive. • You used an older version of Disk Utility.

How do I resolve an invisible Fusion Drive on my Mac?

The Fusion Drive stores the operating system and user data on your Mac, enabling your computer to function properly.

If a Fusion Drive isn't appearing on your Mac, you can't access the data it contains, and it might even prevent your Mac from starting up.

The following solutions can help you recover data from a Mac Fusion drive.

1. Check if the Fusion Drive label is available.

Your drive might be a Fusion Drive if any of the following conditions are true:

• Provides more storage capacity than a single disk. • If you have an SATA interface, the System Information window shows two disks.

To check whether your computer has a Fusion drive without opening it up, follow these steps:

Step 1: From the Apple menu, choose “Get Help.” Click on “Storage” to proceed.

If you see a disk labeled Fusion Drive, click OK and close the window.

2. Merge the split drives into one drive

To revert a separated Fusion Drive back to a single volume, you can continue to use the two disks separately, or you can follow these steps to combine them back into one disk:

1. Restart your computer while holding down Control+R. Release the keys when you see the Apple logo. This will boot your Mac into macOS Recovery.

Step 2: Select Utilities > Terminal. In the terminal window, type “diskutil resetFusion” and press Return. Type “Yes” and press Return.

Step 3: Exit the Terminal. Then, reinstall macOS by clicking “Continue” and following the on-screen instructions. This will cause your computer to boot the Fusion drive as a single disk.

3. Use First Aid to fix a damaged Fusion Drive

Utilize the emergency options to deal with problems with your hard drive. You can inspect and fix the basic structure of your storage drive by following these straightforward steps:

Step 1: Turn on your Mac and press Command + S while it's starting up. This will activate Single User Mode, and you'll see white text on a black screen.

Step 2: Type fsck -fy in the terminal, and press Enter. Do not interrupt the process until it's finished to avoid losing data.

If you see the message “Unable to repair Macintosh HD,” run the command again.

4. Repeat this process until you see the message “The volume Macintosh HD seems to be OK.” Then type exit to quit and restart your Mac.

4. Format the Fusion Drive with the appropriate file system

Windows File Explorer is unable to see a Mac-based storage disk connected to a Windows PC. This issue arises due to incompatibility with data files. Only macOS X can access the APFS or HFS+ file systems on the hard drive. To resolve this, follow these steps:

Step 1: Make a full backup of the drive's contents using an operating system that is appropriate for the drive.

Step 2: Select the FAT32 format to format the disc. (Alternatively, you can format a USB device as FAT32 with a maximum file size of 4 GB.)

Step 3: Restore the backed-up data to the storage media.

1. Install Mac OS X on the non-starting Mac via USB or Thunderbolt. Turn on your Mac device. Then, boot the non-starting Mac and hold down the T key. Release the key when you see the connection symbol.
