Keeping you Mac's hard drive or SSD healthy is hugely important. By monitoring and checking your Mac hard drive's health, you can anticipate potential problems and prevent potentially catastrophic crashes. How do you know if your Mac is working properly?

Fortunately, there are a number of tools available that allow to to check the health of a drive and fix problems before they become serious.

How to Check Hard Drive Space on a Mac OS If the issue is with your Computer or a Laptop you should try using Restoro which can scan the repositories and replace corrupt and missing files. This works in most cases, where the issue is originated due to a system corruption. For Mac users, buying an external HDD already formatted for your system makes getting started much easier. This is because when you initially connect an external HDD made for Mac (to a Mac computer), you won’t be required to format it before you begin transferring files. CrystalDiskMark is a small HDD benchmark utility for your hard drive that enable you to rapidly measure sequential and random read/write speeds. It measure sequential reads/writes speed,measure random 512KB, 4KB, 4KB (Queue Depth=32) reads/writes speed,select test data (Random, 0Fill, 1Fill). Mac: To check hard drive health, Mac users need to use the Disk Utility. Open the Disk Utility and choose “First Aid,” then “Verify Disk.” A window will appear showing you various metrics related to your hard drive health, with things that are fine appearing in black, and things with problems appearing in red.

Best Apps to Check Your Mac Hard Drive Health

One of the best apps for alerting you to potential problems is iStat Menus, available in Setapp. Once you've installed it, iStatMenus sits in your Mac's menu bar and monitors not just your hard drive, but its CPU, RAM and network traffic, among other things.

iStat Menus, and the other disk monitoring tools available for macOS, monitor what is knows as SMART status. SMART stands for Self-Monitoring, Analysis and Reporting Technology and is installed on most hard drives and SSDs. In order to use it, you need software to analyze and display what it finds, and that's where iStatMenus comes in. Check out how to clone mac hard drive.

Monitoring SMART reports won't prevent your hard drive from failing, but it will reduce the likelihood of problems occurring.

Note: As of 2016, Apple no longer allows software tools to check the SMART status of an SSD. So iStatMenus won't repot anything on Macs shipped in 2016 or later.

There are other steps you can take to keep your hard drive or SSD healthy. CleanMyMac X has a number of maintenance routines. While most of them are designed to keep your Mac running smoothly, one of them is an excellent way to keep your hard drive in good shape.

How to verify Startup disk

  1. Launch Setapp, search for CleanMyMac, and open it.
  2. When CleanMyMac has launched, look on the left hand side of its window for the Speed section and click Maintenance.
  3. Click the check box next to 'Repair Disk Permissions' to verify startup disk and then click the 'Run' button at the bottom of the window.
  4. Click OK in the dialog box that opens. Click 'Run' again. View the result

Identifying bad sectors with Disk Drill

Sectors are blocks of space on a disk drive and bad sectors are blocks that cannot be read because, for whatever reason, they're damaged. When Disk Drill attempts to recover data from a hard drive that's failed or one where you've mistakenly deleted files, it marks sectors it can't read from as bad. That means that it won't try to recover data from them in the future.

You can't fix bad sectors, the drive's firmware should identify them and prevent them from being written to. If there's data stored in them and you need to recover it, you're out of luck. But by monitoring how many of them there are on a drive, you can keep an eye on its health and decide whether it's time to replace it, if the number of bad sector starts to increase quickly.

Here's how to identify bad sector in Disk Drill:

  1. Open Disk Drill app in Setapp. When it launches, it will ask if you want to 'Monitor my disks for hardware issues'. Say Yes. If you already have Disk Drill installed but didn't check that option when you launched it the first time, go to the Preferences, click the SMART tab and check the box next to 'Monitor my disks for hardware issues.'
  2. Start a recovery session. In Disk Drill's main window, select the volume 'Macintosh HD', or whatever you've called your Mac's hard drive. Click Recover. Let the recover session run and complete.
  3. Check bad sectors. Once the recovery session has completed and saved, go back to the main Disk Drill window. Click the gear icon next to the drive you ran the recovery session on and click the bottom item on the menu 'Specify bad blocks.' This tool is designed to allow you to tell Disk Drill which blocks are bad and you don't want it to scan, but it will also display bad sectors it has identified.

How to avoid problems from an unhealthy hard drive

Check Hdd For Mac

You should always backup your hard drive regularly, but it's even more important to do it when you suspect your hard drive is having problems. If you identify problems with a hard drive using any of the steps above, you should consider increasing the frequency of your backups and test them to make sure you can recover data if you need to – a backup routine is useless if you can't restore data. You should also consider using Get BackUp Pro to make a complete clone of the drive, that way, in an emergency you can boot from the clone and be back up and running immediately. Click here to read about how to backup your Mac. Get Backup Pro, also available in Setapp, is an excellent tool for making regular backups.

Hard Disk is not Displayed at all in Disk Utility

If your hard disk is not displayed at all in Disk Utility, it will either be out of order or will periodically stop working and will soon stop working altogether. It is also possible that the disk is not physically connected, which is possible if the device is damaged.

Conclusion

I recommend to regularly save a copy of the data through Time Machine or in another way, as well as to monitor the status of the hard disk in the manner described above.
