How to Tell If a Hard Drive Is Failing or Not [Step-by-Step Guide]

Knowing how to tell if a hard drive is failing or not is significantly helpful when your computer pops up some errors, warning you something unusual is occurring.

So how do I define if my disk has failed or if the hard drive on my PC is failing or not? Check and follow the step-by-step guide below with images, and you'll learn the details:

#1. Check If a Hard Drive Surely Has Failed

1. Supported Platform: Windows, & Mac
2. Supported Devices: HDDs, SSDs, External Hard Drives, USB, SD card, etc.

If your disk or Windows computer is having one of the listed issues, it means your disk is highly likely already failed, and you may stop here:

• The computer pops error messages, such as 'disk boot failure', operating system not found', etc.
• BSOD - Blue screen of death, black screen, or even green or red screen.
• Unable to boot - hard drive prevents the computer from booting up.
• Overheating or even burnt - the disk suddenly gets extremely high temperature or even burnt. 

In this case, you can do nothing but send the hard disk for repair or emergency data rescue. Here we have some tips for you:

If your disk doesn't have the above-listed symptoms in Guide 1, you may continue moving on to the next guidelines.

#2. Visual & Physical Inspection

1. Supported Platform: Windows, & Mac
2. Supported Devices: HDDs, SSDs, External Hard Drives, USB, SD card, etc.

Here we'll list some visual and physical inspection tips that you can follow to confirm if your hard drive is failing or not:

• Visual Inspection: if the hard drive becomes invisible on Windows PC, such as hard drive not detected, not showing, or not recognized. Or, the hard drive shows as RAW or unnamed in Disk Management.

• Physical Inspection: Check the outlook of the hard drive and confirm if it's damaged or contains cracks, scratches, or even dents.

#3. Check Symptoms that Indicate a Hard Drive Is Failing

1. Supported Platform: Windows, & Mac
2. Supported Devices: HDDs, SSDs, External Hard Drives, USB, SD card, etc.

If your hard drive or computer shows one or two more symptoms as listed here, you can also confirm that your disk is failing:

• Overheating: A failing hard drive may suddenly overheat or get extremely high temperatures.
• Random Shutdown: When an OS hard drive fails, it can cause the computer to shut down unexpectedly.
• Slow Performance: A failing hard drive may take longer to open files or launch programs or may freeze or crash frequently.
• Strange Noises: A failing hard drive could make clicking, whirring, beeping, whistling, or grinding noises that are abnormal from the usual sound it generated.
• Odd Behavior: When you notice that the disk or computer keeps launching some programs, opening and closing files, or boot loop, it could be the disk is failing. 

#4. Use S.M.A.R.T Monitor Software to Detect Disk Status

1. Supported Platform: Windows
2. Supported Devices: HDDs, SSDs, External Hard Drives, USB, SD card, etc.

The other more technological and practical way to identify if your disk is having problems and failing is to turn to reliable S.M.A.R.T hard drive monitor software for help. 

Here are some tips that you can follow and take for selecting a qualified disk S.M.A.R.T benchmark tool:

If you are in favor of a classic or old-school style interface tool for checking the disk status, you may turn to CrystalDiskInfo or Hard Disk Sentinel for reference. 

For Windows beginners or if you have no disk management experience, I'd like to recommend you try EaseUS Partition Master personally. Its new disk benchmark feature - Disk Health, can fulfill your need to check S.M.A.R.T data on your drive and generate an easy and understandable report for you.

Here is the process that you may follow to check a disk S.M.A.R.T status and confirm if it's failing or not:

1. 1. Launch EaseUS Partition Master, go to the Discover section, and click "Disk Health".
2. 2. Select the target hard drive you'd like to check its state, and then view the scanning report.

Here are some tips for you to interpret the report and confirm if the disk is failing:

• Status: if the disk status marks "Good",  your disk is firmly all good. If it's marked with other states, such as "Bad", "Caution", your disk is experiencing terrible issues, and surely it's failing. If it shows as "Unknown", your hard drive is having a recognizing issue, or it may even get corrupted or die.
• Temperature: if the hard drive goes up to 60 degrees, your disk is surely failing or even getting worse issues.
• Light State of Each S.M.A.R.T Data: if you notice some or multiple lights in front of each S.M.A.R.T data turn to red, it means your disk is surely now having some errors and failing. 

Alongside checking the disk health state, and telling you the status of your hard drive, EaseUS Partition Master also provides you with some bonus features to fix a failing drive, including:

• Surface test hard drive to find existing bad sectors
• Check file system to fix corrupted file systems and some soft bad sectors
• Rebuild MBR to fix and repair corrupted or damaged MBR partition table on a corrupted or unbootable computer disk
• Benchmark hard drive and test disk speed in Windows

#5. Further Tip - Run CMD to Tell If A Hard Drive Is Failing 

1. Supported Platform: Windows
2. Supported Devices: HDDs, SSDs, External Hard Drives, USB, SD card, etc.

The last efficient way that Windows users can apply to test if their hard drives are failing is turning to run CMD command lines as listed here:

• Press Windows + R keys, type cmd in the Run dialog and hit Enter.
• Type wmic and hit Enter.
• Type diskdrive get status and hit Enter.

The diskdrive get status command that will order the computer to check the hard drive health state on your PC. If CMD reports your disk status is Good or OK, your disk is healthy. If it lists a bad result, your disk is probably failing. 

• Type chkdsk in command prompt and hit Enter.

The chkdsk command will list all file system errors in your computer drive with a basic scan. You can also apply the chkdsk /f /r /x command to check and fix any fond errors in your target drive. When CMD reports it found errors and fixed them for you, it means that your hard drive is also failing.
