Repairing hard drives is not something that anybody can do, especially when you have to repair a Mac hard drive. The best thing to do for a hassle-free experience is to contact Apple support and have it repaired. However, hard drives tend to show signs of aging or wear before they go out. These signs or symptoms are early warnings that your drive is going to fail in the near future.

As a user, what you need to do is flag these signs and act accordingly. We will list out some of the symptoms of Mac hard drive not working so that you can act fast and save your data.

Part 1: Signs That Your Mac Hard Drive Not Working

Hard drive deterioration is an inevitable thing and you need to be prepared for it. No matter how costly the drive is, it will stop working after some time. However, you can be in safe if you pay attention to your Mac hard drive and its symptoms. We will list out a few signs exhibited by failing Mac hard drives so that you can pick them up easily if they happen to you.

Frequent crashes: As the health of the Mac hard drive becomes worse, it will start to crash while in use. This will continue to a point until you see this as a pattern. Frequency hard drive crashes can also cause a great deal of inconvenience because it may result in data loss if you are working on something.

Weird Noises from the hard drive: Hard drives are not ultra-quiet devices. They produce a slight humming noise which is barely audible when they are in use. However, if you hear scratching or clicking noises from them, it is mostly because of the faulty hardware within a hard drive.

The computer becomes slow: You will notice that your Mac takes more time to access a file or read a file than it would normally take. In essence, Mac will become slower and slower over a short period of time. This is also a sign that there is something wrong with the hard drive.

Data becomes corrupted: A failing Mac hard disk will have problems saving a file after its use. This is easily noticeable as the files that you save will be corrupted the next time you open them. It creates a massive headache for the user, but the problem lies with the Mac hard drive.

Low S.M.A.R.T score: The Self-Monitoring, Analysis, and Reporting Technology is that collection of tests that will help you understand the health of your Mac hard drive. Run a SMART scan on your hard drive and evaluate the results. If there are any problems with the hard drive like a bad controller or bad sectors, it will be clearly shown by the SMART scan.

There are many more signs that help us identify a problematic Mac hard drive, but these five symptoms almost always accompany every other one. So if you spot these for your Mac hard drive, then your Mac HDD might need a repair job sooner than you think.
