All Macs have this handy little tool called Disk Utility, which can be used for many things. It’s just hidden somewhere in the Utilities folder under the Applications folder. If you want to locate it the fast way, you can always use Spotlight.
Now in what ways can you use Disk Utility? Here are some of its known uses:
- Format, manage, or erase internal and external storage disks
- Manage or add volumes
- Organize your disk into partitions
- Work with Redundant Array of Independent Disks (RAID) sets
- Create disk image files for archiving or backing up purposes
- Fix and diagnose problems with damaged disks or volumes
When to Use Disk Utility
As mentioned above, there are many instances where you can use Disk Utility. But many Mac users usually only open it if they experience any of the following problems:
- Macs don’t start up.
- External devices don’t work.
- Apps quit unexpectedly.
- Files are corrupted.
- A disk needs to be ejected, mounted, or unmounted.
- A file system needs to be changed.
- There is a problem with the startup disk.
- A damaged disk needs to be repaired.
- A disk needs to be partitioned, formatted, or erased.
The Basic Purpose of Disk Utility
If you suspect that there is something wrong with your Mac’s internal drives or external storage devices, the first thing you should do is to use the First Aid feature of Disk Utility.
Pro Tip: Scan your Mac for performance issues, junk files, harmful apps, and security threats
that can cause system issues or slow performance.
This feature will run different checks on your drives. Once it detects an error or a threat, it will automatically do its job and repair the problem.
Depending on your macOS version, the way that First Aid will repair your drives will also vary. However, running First Aid in all versions is generally the same. Here’s how:
- Go to Disk Utility.
- Select the drive that you suspect has problems.
- Click First Aid.
- Disk Utility will then start checking the partition maps on the drive. It will also check each volume. If a problem is found, it will attempt to repair it.
If Disk Utility tells you that a specific volume or disk is at the brink of failing, you need to back up its contents as soon as possible.
