4 Mac Internal Hard Drive Problems and Solutions

  • by

The Mac is not just your average machine. It is a lifestyle. You save up to buy arguably the most reliable and smooth computer on the market to take your experience to the next level – only to run into hard drive problems.

Mac has better quality components and operating systems than Windows. Usually, everything just works much better, but you can run into unique problems. Unfortunately, even the most resilient machines will experience problems from time to time.

One of the most common issues Mac users encounter is hard drive problems. After all that technological advancement, why does the Mac internal hard drive face problems? Let’s dig a little deeper to understand these problems and find out how to solve them.

Problem: Mac External Hard Drive Is Read-Only

If your Mac is connected to an external hard drive formatted as NTFS, it may be read-only. This means that you can’t write or modify any files on the drive. This is because NTFS is a Windows-specific file system, and macOS doesn’t have built-in support for it. However, there are a few ways to fix this problem.


One way to fix the problem is to format NTFS on Mac as HFS+, which is the native file system for macOS.

Another way to fully access a read-only drive is to use a third-party driver such as Microsoft NTFS for Mac.

Problem: Mac Hard Drive Is Running Slow

Your Mac’s hard drive stores your files, applications, and other data. Over time, your hard drive can become cluttered with files you no longer need and applications you no longer use. This can lead to a slowdown in performance.


You can do a few things to help speed up your hard drive and get it running at its best.

First, look at what is taking up space on your hard drive. You can do this by opening the Finder and selecting all files from the sidebar. This will show you a list of all the files and folders on your hard drive, including their size. See if there are any files you no longer need. If so, delete them to free up space.

Next, run a disk cleanup utility to remove any temporary or junk files from your hard drive. This will scan your hard drive and remove any unnecessary files, which can help speed up your computer.

Finally, defragment your hard drive. Over time, the data on your hard drive can become fragmented, meaning it is spread out across the disk in small pieces. To fix this, you can use a disk defragmentation tool. This will reorganize the data on your hard drive and make it easier for your computer to access files.

Bonus tip: Use third-party platforms such as Steam to directly store games and software on the cloud to prevent them from making temp data and cache files.

Following these tips can help speed up your hard drive and keep it running at its best.

Problem: Hard Drive Space Is Disappearing

Low disk space on Mac is another common problem. You do everything to keep your drive’s space free, but it still keeps on shrinking. Suddenly, you’re left with barely any room to work with. It can be really frustrating trying to figure out where all that space went.

One of the most common is that your system has accumulated a lot of cache files. These temporary files are created when you use certain apps or visit certain websites. Other reasons can be duplicate files.

Finally, large and outdated files can also contribute to a full hard drive. Things like old backups, unused programs, and even certain types of data files can take up a lot of space. If you don’t need them anymore, deleting them can give you back some valuable storage space.


If your Mac’s hard drive is starting to fill up, don’t worry. There are a few simple ways to free up some space.

Start by cleaning out your system’s cache files. You can do this by following these simple steps:

  1. Open Finder
  2. Click on “Go”
  3. Click on “Home”
  4. Select the “Cog” icon on the top, then click on “Show view options”
  5. Check the box “Show library folder” in the pop-up window
  6. Click the “Library” folder
  7. Go to “Cache”
  8. Select all and move to trash

Once you have gotten rid of the cache, delete any duplicate files you may have. Finally, look at your large and outdated files to see if you can delete anything. You can quickly and easily reclaim some of that precious hard drive space by taking these steps.

Problem: Data Permanently Deleted from Hard Drive

Permanent data loss is one of the most worrisome and problematic situations Mac users can find themselves in. This usually happens due to user error – for example, accidentally deleting files or formatting the drive. Other ways include physical damage to the drive, corruption of the file system, or even a virus infection.


You can recover your data by using data recovery software, which can often retrieve deleted files or repair damaged file systems.

However, the data will be lost forever if the hard drive is physically damaged. To prevent this, you can use Time Machine to back up your hard drives regularly. You can retrieve the data from the Time machine on your computer.

To do this:

  1. Go to the menu bar
  2. Search “Time machine” and open it
  3. Select and restore all the data or scroll through to find a particular file or folder to restore.
