Method 1. Turn off all the external storage devices.

So, the first thing you can try to do is turn off all external storage devices.

For example, an external hard drive, flash drives, SD cards, even the mouse, keyboard, etc. After that, turn on the computer again and connect all devices one by one. Error code 0xc00000e9 should disappear and no longer bother you. If, however, this method did not help, do not be discouraged. Proceed to the next method.

Method 2. Update drivers to remove the error 0xc00000e9

Update drivers to remove the error 0xc00000e9.

Perhaps the reason for the error is that the drivers are outdated.

Try to download all available updates. All you need is the internet and the driver version. Go to the official website of the hard drive manufacturer and install all available updates using the Installation Wizard. After that, do not forget to restart your computer.

Unfortunately, sometimes error 0xc00000e9 does not disappear after that. So the reason is different. Try method 3.

Method 3. Run SFC to remove the 0xc00000e9 error

The SFC tool is a built-in Windows feature and does a good job of finding and fixing system errors; in particular, with error 0xc00000e9. In order to use this method, read the following instructions:

Use SFC to remove the 0xc00000e9 error.

Right-click on Start and select “Command Prompt (administrator)”. Next, on the command line, type the following command: “SFC / SCANNOW” and press Enter. Scanning of the disk will happen and, subsequently, found errors will be corrected. After the process is complete, restart the computer and check whether it works correctly. If not? Perhaps the following method will help you.

Method 4. Restore BIOS to default settings

There may have been some changes in the BIOS settings; this will easily lead to an 0xc00000e9 error in Windows 10. Therefore, you need to go into the BIOS by pressing the F2 key. Next, go to the settings and set them as default. Then exit the program and restart the computer.

If the method did not help, then the settings are OK and the reason is different.

Method 5. Use DiskInternals Partition Recovery

This method, unlike the previous ones, gives almost 100% results.

This software rebuilds the file system and finds the maximum amount of data from the device. Therefore, this is what you need. The application recovers all file types up to 1 PB!

DiskInternals Partition Recovery works with the following file systems: FAT12, ReFS, UFS, HFS, NTFS, ReiserFS, Reiser4, XFS Ext2, Ext3, and Ext4.

Use a free trial version of the product first before buying a license. Only after you make sure that your data has been restored, you need to purchase a license and a license key. You can use one of three recovery wizards: Partition Recovery Wizard, NTFS Recovery Wizard, and FAT Recovery Wizard.

They will help you recover data, even if you are doing it for the first time. There is also a free preview function that allows you to selectively restore files and also verify the quality of the files found.

As you can see, there is not a single minus to this method. Therefore, the right choice is yours!

Method 6. Run CHKDSK and remove the 0xc00000e9 error

CHKDSK helps you fix error code 0xc00000e9. And it is best to use this method only after the data from the disk is recovered and stored in a safe place, as CHKDSK cuts data into 512 KB pieces.

After CHKDSK has been run, restart the computer. Then make sure that the error code 0xc00000e9 no longer bothers you.

Hopefully, you have completely dealt with this problem!
