SOLVED! Scanning And Repairing Drive Stuck At 100 – Avoid It

Despite the popularity of Windows, the performance of the operating system from Microsoft still suffers from all sorts of errors, especially disk ones. Usually, if Windows notices disk errors as it boots up, it will initiate a disk check that involves the scanning and repairing of drives. Assuming that the process runs smoothly, Windows users could resume using their devices. Nonetheless, scanning and repairing drive stuck at 100 is still the topic of many complaints about the disk check during boot up. 

What Might Have Gone Wrong 

Overall, the length of the scanning and repairing of drives on Windows PC depends on the size of the drive, the severity of the error, etc. Still, if the percentage of the process is stuck at 100, likely causes include issues with Master boot record file (MBR), bad sectors on the drive and so on. 

Approaches To The Situation


To put it plainly, waiting is the best thing to do in a lot of cases. The time it takes to scan and repair the drive depends on your PC. If your PC possesses enough resources and processing power, the whole thing will wrap up quickly. However, if the drive is in poor shape, the scanning and repairing of drives could take hours to finish. 

Error Checking

One effective and efficient fix for scanning and repairing drive stuck at 100 is to run Error Checking after booting your PC in Safe Mode. In the case that you have an installation DVD for Windows 10, feel free to use it. If necessary, you could use the Windows Media Creation Tool to create installation media.

  • Step 1: Boot from the installation media. Skip the first screen and select Repair Your Computer.
  • Step 2: Select Troubleshoot > Advanced option > Startup Settings then choose Restart.
  • Step 3: When the computer restarts, a list of startup settings will appear. You could pick either F4 or 4 to boot into safe mode or F5 or 5 to enable the safe mode with networking.
  • Step 4: Open This PC and right-click the drive that Windows is having issues scanning with, and select Properties.
  • Step 5: Navigate to the Tools tab and select Check.

System File Checker 

If you suspect corruption in system files is responsible, System File Checker will come in handy. SFC will scan for damaged system files and fix them in a blink of an eye.

  • Step 1: Boot into Safe Mode, go to Search bar, type Cmd, right-click Command Prompt and pick Run as administrator. 
  • Step 2: In Command Prompt (Admin), run the command sfc /scannow
  • Step 3: Wait until the scan completes and determine whether the issue persists. 

‘repair-volume -driveletter’ Command 

  • Step 1: Boot into Safe mode, right-click the Start menu and pick Windows PowerShell (admin).
  • Step 2: Select Yes for UAC prompt. In Windows PowerShell (Admin), run the command repair-volume -driveletter X (X represents the name of the drive).
  • Step 3: Allow the command to run all the way. 

After you finish, restart your computer in normal mode. If things go well, you no longer have to put up with the scanning and repairing of drives.

CHKDSK Command

Once it comes to scanning and repairing drive stuck at 100, the CHKDSK command works wonders at times. You can also use additional options to compel CHKDSK to correct disk problems.

  • Step 1: Boot into Safe Mode, go to Search bar, type Cmd, right-click Command Prompt and pick Run as administrator. 
  • Step 2: Run the command chkdsk /f /r

In the command, Chkdsk stands for Check Disk Faults. C: is the drive letter, /r for locating bad sectors and recovering usable information and /f is for fixing disk errors.

Press Y to get chkdsk to run on the next bootup and restart your computer. That will initiate the scan of disc drives and repair of problems. All you have to do is to wait until the process wraps up. 

Stop Windows From Scanning And Repairing Drives

In case you don’t know, you could disable the disk check altogether. By tapping a random key during bootup, you could skip the scanning and repairing of drives.
