6 Effective Solutions to Resolve ERROR_DISCARDED 157 (0x9D) Issue

The Error_Discarded 157 (0x9D) accompanied by the message “The segment is already discarded and cannot be locked” arises when a process attempts to access a memory segment or a buffer/file that has already been discarded or rendered inaccessible. This issue may surface while using device drivers, memory buffers, or during certain kernel-level operations.

Initially, verify that your system has adequate RAM and is free from memory leaks. Next, monitor your memory usage and close any unnecessary applications to alleviate the burden. Restarting the affected application or your computer can also help in refreshing the state of the hardware or memory segment.

How to Resolve ERROR_DISCARDED 157 (0x9D)?

1. Update or Reinstall the Problematic Driver

If Windows fails to locate the latest driver version, visit the manufacturer’s website to download it directly. Alternatively, consider using a trusted driver updater tool to facilitate the scan and update process quickly. If you have the most recent driver and the error persists, attempting to reinstall the driver may help. To do this, follow these steps:

1. Open Device Manager again and find the troublesome driver.

3. You will see a prompt indicating that the scan will occur on restart. Type Y and press Enter to schedule it.
4. Now, restart your computer and await the completion of the scan.

3. Temporarily Disable the Windows Firewall

1. Press Windows + R to launch the Run dialog.
2. Input eventvwr.msc and click OK to open the Event Viewer.
3. On the left pane, navigate to Windows Logs > System or Application.
4. Look for any errors or warnings related to memory management, hardware, or any application that may be triggering the Error_Discarded message.

5. Carry Out an SFC Scan

1. Press the Windows key, type cmd in the search bar, and select Run as administrator.

6. Click Finish to start the restoration process.

Your computer will restart and revert the system settings to the selected restore point. If after booting you encounter a message stating that System Restore was not successfully completed, it may be due to conflicting drivers or corrupted system files; in this case, try the remedies detailed in this guide.
