• While you restart your system, Windows automatically installs the disk drivers.
• You can try performing the read/write operation on the disk after reboot to check if the error persists.

Method 2: Run Check Disk Scan

To scan the hard drive for the disk errors, bad sectors, and file system errors, you can run the Check Disk (CHKDSK) command. Follow the below-given steps:

• Open Command Prompt as Administrator and type in the following command:

chkdsk /f /r X:

Where X is the drive letter

• Press the Enter key and wait for the Scan to finish. Once done, restart the system.

Method 3: Run SFC Scan

Damaged or corrupt critical Windows system files may result in the error code ‘0xc00000e9’. Microsoft Windows has an inbuilt utility – System File Checker (SFC) that helps you scan and replace damaged or corrupt Windows system files. To run SFC scan, proceed with the below-given steps:
