So what does this message, one of your hard drives needs to be checked for consistency mean? Simply put, it means that either the file system is corrupt or the system files have issues.
Microsoft created the CHKDSK Windows function to check and assure disk integrity for faulty sectors and fragment spaces to optimize disk performance and boost overall effectiveness. Windows asks the user to perform a CHKDSK when it detects faults on a drive.
So, in this article, we shall discuss the reasons for the message that one of your hard drives needs to be checked for consistency and steps on how to resolve this issue. Read on to find out more.
Why It Says One of Your Disks Needs to Be Checked for Consistency
The primary reason you receive the message is that Windows has detected file system corruption, and Windows OS needs to use the CHKDSK tool to ensure that. The reason for corruption can be many; below, we list some methods.
- Improper system shutdown: The message one of your hard drives needs to be checked for consistency might display on your screen when you turn on your computer if your PC does not shut down correctly. An abrupt shutdown is unsuitable for your PC, thus demanding a disk check.
- Sudden power outage: The second reason is a power outage. If your PC does not have a power backup and if your system abruptly shuts down due to power failure, this can cause your PC to demand a hard disk checkup.
- Windows computer froze: If your computer freezes up for unknown reasons, you might force your PC to shut down. This abrupt shutting down of your PC might make one of your hard drives need to be checked for consistent messages.
- A USB disk is removed abnormally: Another problem is pulling the flash drive out of the computer while Windows is still using it might cause problems to the PC. This message is due to the abnormal removal of a USB drive.
Solve One of Your Disks Needs to Be Checked for Consistency Error
It is generally advised to complete the disk check when you see the error message requesting it. But if you accidentally skipped it, you can check the five fixes below to solve the issue that one of your disks needs to be checked for a consistency message appearing when you turn on your computer.
Fix 1. Use the Registry Editor to Fix It
You can start by disabling automatic disk checks using the Registry Editor.
Step 1. Type Regedit on the Start menu.
Step 2. Select "Registry Editor".
Step 3. On the Registry Editor window, on the left pane, expand the following option:
Step 4. Find and double-click the "BootExecute" string. If the value data of Boot execute is set to autocheck autochk * /r\DosDevice\C: Please change it to autocheck autochk * and press OK to save the changes.
Check whether the error—Your Disks Needs to Be Checked for Consistency— reappears after restarting your computer.
- We suggest taking a backup or creating a system restore before you change anything in the registry. If you accidentally delete something, then Windows will become unusable.
Fix 2. Utilize the CHKDSK Command
The following fix is a manual disk check by launching CHKDSK from an Elevated Command Prompt, which gives users full rights and is an elevated command prompt version. To do this, follow the steps given below:
Step 1. Press the Windows key + R to open the Run dialogue box.
Step 2. Type CMD and press Ctrl + Shift + Enter to boot Command Prompt on Windows 10.
Step 3. Inside the new window, type in the following command: chkdsk /r, and press Enter.
If the disk consistency is on the C drive, you need to restart your PC and schedule the Run. You will get the prompt about it. Press Y. If it's any other drive, you can run the tool without a restart.
After the process, restart your PC and check if the message reappears.
Fix 3. Run Fsutil Dirty Query Command
Although this technique is rare as others, some users claim that they could resolve one of your disk's needs to be checked for consistency errors by running the command. On Windows operating systems, the Fsutil.exe application aids users in controlling the settings of various file systems. Follow the instructions given below to run this command:
Step 1. Type cmd into the Start menu.
Step 2. Right-click on Command Prompt and select Run as administrator from the drop-down menu.
Step 3. On the new window, type the following command and press Enter. fsutil dirty query X:
(Replace the letter X with the problematic drive letter of your computer.)
Step 4. If the disc drive is dirty, as shown in the window, type the following command: chkdsk X: /f /x and press Enter. Remember to replace the letter X.
The option "/r" tells the tool to find the bad sectors on the drive and recover readable information, while the "/x" forces the industry to dismount before the process starts.
If the prompt shows that the disk is not dirty, the process is complete; you can restart the computer and check if the message reappears.
Fix 4. Use Disk Defragment
The method to solve this issue is the Disk Defragment method. Here is how you do it:
Step 1. Open File Explorer, go to This PC and find the hard drive.
Step 2. Right-click on it and choose "Properties".
Step 3. Next, select the "Tools" tab.
Step 4. Click the "Optimize button" under the Optimize and defragment option.
Step 5. On the new window under Status, choose the drives you want to optimize and click on the Optimize button.
Fix 5. Format the Disk
While formatting a disk in Windows can effectively fix a drive, the process is complicated. It will delete all the data. Therefore, before implementing this fix, you should move your files from the affected drive to other secure disks.
Step 1. Go to This PC and choose the affected hard drive.
Step 2. Right-click and select "Format".
Step 3. Choose the File System, check the "Quick Format" column, and press Start.
After the format process, restart your computer and check if one of your hard drives needs to be checked for consistency message appearing again.
