Sometimes, when you start up your computer as normal, suddenly a black screen appears saying one of your disks needs to be checked for consistency. This post focuses on the “one of your disks needs to be checked for consistency” error message and provides you with four effective ways to fix the issue and powerful hard drive data recovery software to recover data from the problematic disk.

What does this error message “your disk needs to be checked for consistency” mean? Simply put, it is a warning that a file system on your disk may be corrupted and not be completely safe to use.

Windows users can use this CHKDSK utility to check their disks’ status and fix errors promptly, such as the “your disk needs to be checked for consistency” error. CHKDSK(check disk) is a command that is designed to check and assure disk integrity for faulty sectors and fragment spaces to optimize disk performance. It can display the disk status and help users find and repair bug-causing errors easily.

Your Disk Needs to Be Checked for Consistency on Windows

Most Windows users have likely encountered this problem. When they boot up the computer, everything seems normal, but then a black screen unexpectedly appears. The on-screen notification states that the hard drive requires a consistency check. The full message reads:

the error message

This black CHKDSK window indicates that a hard disk check is in progress. Pressing any key before the countdown ends will cancel the disk check. Nevertheless, after rebooting the computer, you will receive the same error message since the operating system still believes that the drive requires a scan and check. If no key is pressed, the disk check will be performed automatically.

Why It Says Your Disk Needs to Be Checked for Consistency

As mentioned above, the primary reason for the occurrence of error messages is that Windows has detected file system corruption. Windows operating system scans your PC and believes the drive needs to be checked. Therefore, it runs CHKDSK to check and fix the error automatically. Here are several causes of file system corruption:

  1. Improper system shutdown: The error message might display if you shut down the computer incorrectly. For instance, you directly shut down your PC while programs are still running.
  2. Improper removal of a USB disk: Once you don’t safely eject the USB before the Windows process is completely terminated, the Windows operating system will likely mark your device as “dirty” and run CHKDSK after turning on your PC next time.
  3. Windows operating system: Sometimes, the Windows operating system will scan your disks automatically even though you have checked the disks completely.
  4. Power outage: If your computer does not have a power backup, your computer may have a sudden power outage, causing your PC to check the hard disk.
  5. Freezing of Windows computer: You might have fixed the issue that the computer keeps freezing by force shutting down your PC. This might have resulted in the error “the disk needs to be checked for consistency.”

2 Ways to Recover Lost Files

If you receive the “your disk needs to be checked for consistency” error message on your computer and choose to complete the CHKDSK, it may cause files lost. Considering this, you need to rescue lost files from your disk. If your computer can boot up normally, the following two methods work effectively.

Method 1: Recover Data from Found.000 Folder

In this way, you can recover your lost files from your disks manually without downloading any other data recovery software.

Note:
This method cannot work if you don’t remember the correct extension or there are too many files to change.

Step 1: You will receive a message saying “Conver lost chains to files <Y / N>?” before CHKDSK starts deleting your files. In this window, you need to enter Y so that the disk check operation will save each lost chain in found.000 folder. This folder locates the root directory of the disk being checked. If you enter N, the operating system will fix the disk without saving lost content of lost allocation units.

Step 2: After CHKDSK completes, you need to find the Found.000 folder which is hidden by default. To view this folder, you can show hidden files and folders in File Explorer by enabling the Hidden item option from the View bar.

enable Hidden items

Step 3: You may see the Found.000 folder, double-click it, and there are some .chk files. You may find that the files are not accessible. Therefore, you need to change the file extension to the correct one. For instance, if you need to restore a JPG picture from this folder, you can change the file extension of the target file from .chk to .jpg. After the operation, the file can be opened.

Method 2: Recover Lost Files with Free Data Recovery Software
