​Reasons Why ​Your PC May ​Be Repairing ​Disk Errors [Details]

Here’s a detailed guideline of why your P.C. has some issues on disk. And how you can resolve it by knowing why it happens. Sometimes, it may take longer. But, But Be cool. And read on:

​Hard Drive ​Failure

A failing ​hard drive ​is the most ​common cause ​of disk errors. ​The hard ​disk stores all ​data on ​your computer and ​can wear ​out over time, ​making it ​necessary to repair ​any errors ​detected. If your ​hard drive ​fails, you might ​hear clicking ​or humming sounds ​when your ​system is on. 

​Moreover, some ​applications might not ​load, and ​you’ll experience delays ​in opening ​files. To prevent ​hard drive ​failure, update your ​antivirus regularly ​and stop running ​too many ​programs on your ​computer.

Power ​Outages

Power outages ​can also ​cause errors in ​your hard ​drive. When your ​computer is ​not shut down ​properly, the system files can have incomplete ​writing or ​reading processes, resulting in ​disk errors. ​You can avoid ​this using ​a U.P.S. (Uninterruptible ​Power Supply) ​to protect your ​computer from ​sudden electrical power ​surges.

Physical ​Damage to Your ​Hard Disk

​Physical damage to ​your hard ​disk can cause ​errors. These ​damages include falls, ​liquid spills, ​or exposure to ​high magnetic ​fields. Once damaged, ​your hard ​disk will require ​repairs or ​replacement. Therefore, ​avoid exposing ​your computer to ​these elements ​and always store ​it safely, ​preferably in a ​hard casing.

​O.S. Issues

Operating ​system (O.S.) ​issues can also ​cause errors ​in your hard ​drive. Older ​operating systems or ​software can ​develop bugs and ​need to ​communicate appropriately with ​the hard ​drive. This can ​lead to ​data loss or ​system freezes. ​Regular updates and ​modern systems ​can protect your ​data and ​prevent potential errors.

​Corrupted System ​Files

Corrupted system ​files are ​another cause of ​disk errors. ​Any damage ​to them ​can result in ​system malfunction ​and disk errors. ​You can ​repair corrupted system ​files by ​running the system ​file checker ​tool (S.F.C.) or ​restoring the ​operating system to ​a previous ​date.

​Fix P.C ​Repairing Disk Errors: Ultimate Solution Why Is My P.C. Repairing Disk Errors

​If you ​encounter the “Repairing ​disk errors” ​issue preventing you ​from booting ​into Windows 10/11, ​you can ​try the following ​troubleshooting steps:

Allow ​the Disk ​Repair Process to ​Finish

Give ​the system sufficient ​time to ​scan and complete ​the repair ​process. You can ​return to ​your computer after ​a few ​hours to check ​if it ​has finished. If ​it still ​runs after several ​hours, you ​can manually power ​off your ​computer by pressing ​the power ​button until it ​turns off. ​This might help ​the computer ​to boot into ​Windows normally.

​Disconnect ​External Drives

​Peripheral devices, such ​as USB ​drives and recently ​installed hardware ​like memory, can ​sometimes cause ​disk errors. Try ​disconnecting unnecessary ​external drives and ​newly installed hardware.

​Run ​Startup Repair

Step #1: ​Launch the Automatic ​repair tool.

​To open the ​Automatic repair ​tool, there is ​no need ​for additional CDs ​or iso ​files. It is ​a built-in ​recovery feature in ​Windows. 

Follow ​these steps:

     a. ​Manually turn ​off the computer ​by pressing ​the power key ​until it ​shuts down.

     b. ​Turn on ​the computer and ​wait for ​the B.S.O.D (Blue ​Screen of ​Death) to appear.

     ​c. Repeat ​steps a and ​b three ​times consecutively.

     d. ​After the ​third improper shutdown, ​Windows 10 ​will attempt to ​launch the ​Windows RE (Recovery ​Environment).

Step #2: Access ​advanced options.

When ​your computer ​displays the message ​”Your P.C.  ​did not start ​correctly,” click ​the “Advanced options” ​button.

Step #3: Navigate ​to troubleshooting options.

Under the ​”Choose an option” ​menu, click ​”Troubleshoot,” and then ​select “Advanced ​options.”

Step #4: Choose Startup ​Repair.

From ​the available options, ​select “Startup ​Repair.”

If Startup ​Repair can ​resolve the booting ​issue, your ​computer can successfully ​boot into ​Windows.

​Booting into ​Safe Mode with ​Network

To ​boot into Windows ​RE, repeatedly ​power off and ​on your ​computer, following the ​same step ​as in Fix ​#3.

In ​the “Choose an ​option” section, ​select Troubleshoot > ​Advanced options ​> Startup Settings ​> Restart. ​Your computer will ​restart automatically.

Press ​F5 on ​your keyboard.

Running ​S.F.C. Scannow in ​Command Prompt

​After booting into ​Windows Safe ​Mode, you can ​run S.F.C. ​(System File Checker). Intent to verify ​and repair problematic ​system files.

  • Open the elevated ​Command Prompt.
  • Open the search ​menu and ​type in “cmd”.
  • ​Find the Command ​Prompt under the ​best match.
  • Then click “Run ​as administrator”.
  • ​In a user ​account control prompt, ​select “Yes”.
  • In the elevated ​command line ​window, type “sfc ​/scannow” and ​press Enter.
  • Ensure ​a space ​between “sfc” and ​”/scan now” ​exists.

The system ​scan will ​begin and may ​take some ​time to finish. ​Please be ​patient.

When the ​scanning is ​complete, you should ​see the ​message “Windows Resource ​Protection found ​corrupt files and ​successfully repaired ​them”. If S.F.C. ​is not ​working or corrupted ​files cannot ​be repaired, you ​may try ​other fixes.

DiskGenius ​is a ​reliable disk repair ​software offering ​a free solution ​for ​personal and business ​users. With ​this tool, you ​can assess ​the health of ​your hard ​drives, S.S.D., and ​USB drives ​by viewing S.M.A.R.T. ​information and ​repairing bad sectors. ​

To check ​for bad sectors, ​it is ​recommended to connect ​the drive ​to another computer ​as a ​secondary drive or ​boot into ​Windows PE instead ​of Safe ​Mode. This avoids ​accessing the ​drive while checking ​for bad ​sectors, ensuring accurate ​test results.

​Please note that ​severe physical ​damage may render ​a hard ​drive irreparable, requiring ​replacement.

​If the issue ​persists, it ​could indicate a ​more severe ​problem with the ​operating system ​or hardware components. ​In such ​cases, it’s advisable ​to seek ​professional assistance from ​the computer’s ​manufacturer for diagnosis ​and resolution.


In ​conclusion, disk ​errors can threaten ​your computer’s ​health. Hard drive ​failure, power ​outages, physical damages, ​O.S. issues, ​and corrupted system ​files are ​the primary causes ​of disk ​errors. 

However, you ​can avoid ​disk errors by ​updating your ​antivirus, using a ​U.P.S., storing ​your computer safely, ​using modern ​systems, and running ​system file ​checker tools. By ​taking these ​simple steps, you ​can improve ​the performance of ​your computer ​and prevent further ​damage to ​your hard drive.


Can I ​interrupt the ​scan and repair ​process for ​a drive?

When ​dealing with ​scan and repair ​for disk ​errors, it is ​recommended to ​let it finish ​overnight if ​it’s the first ​time encountering ​the error. Usually, ​it automatically ​performs the scan ​and repair ​during system booting. 

​Although it ​effectively resolves such ​problems, it ​may take considerable ​time. Therefore, allowing ​your computer ​to continue the ​repair process ​overnight is advisable. ​However, if ​the repair persists ​throughout the ​night, you can ​try some ​troubleshooting steps mentioned ​in this ​guide.

How can ​you determine ​if the automatic ​repair process ​is stuck?

If ​your computer ​exhibits the following ​symptoms, it ​is likely stuck ​in a ​Windows automatic repair ​loop:

The ​computer is stuck ​on a ​black screen instead ​of booting ​into Windows, and ​error messages ​like “Diagnosing your ​P.C.” or ​”Preparing automatic repair” ​appear.

The ​error message “Repairing ​automatic repair” ​or “repairing disk ​error” continues ​to display on ​the black ​screen without any ​progress toward ​entering Windows.

A ​blue screen ​appears with messages ​like “Automatic ​repair couldn’t repair ​your P.C.”, ​”Your P.C. did ​not start ​correctly,” or “Your ​P.C. needs ​to restart.”

Restarting ​the computer ​does not resolve ​the issue.

​How can the ​auto-repair disk ​problem be fixed?

​If your ​computer is stuck ​in an ​automatic repair loop, ​you can ​try the following ​troubleshooting steps:

  • ​Run the S.F.C. ​command in ​safe mode.
  • Restore ​and fix ​corrupted registry files.
  • ​Scan the ​computer using antivirus ​software.
  • Perform ​disk checking to ​fix disk ​bad sectors.
  • Perform ​a system ​restore.

Does the ​repair process ​for disk errors ​always work?

​Yes, the repair ​process is ​effective in many ​cases. However, ​it may not ​fix all ​disk errors, especially ​if the ​problem is severe. ​That’s why ​your computer may ​get stuck ​during the repair ​process and ​enter a restart loop.
