Bhtsddr.sys BSOD error
on Windows

Hi, I keep getting bhtsddr.sys BSOD crashes in Windows. I'd appreciate you'd explain on how to solve this ASAP. Thanks.

Blue Screen of Death (BSOD) is a critical error screen in Windows that safeguards the system from potential damage by forcibly shutting it down upon encountering a severe issue. During a BSOD, error codes are displayed to aid in diagnosing the problem. In certain instances, the faulting file responsible for the crash is also revealed, and bhtsddr.sys is one such file associated with this scenario. It denotes the BayHubTech SD Reader Driver.

The bhtsddr.sys BSOD error often occurs due to issues with the BayHubTech SD Reader Driver. This driver facilitates communication between the operating system and SD card readers. The error may result from outdated or incompatible drivers. To address this issue, you can update the driver through the device manager or reinstall it entirely. Ensuring that your operating system is up to date with the latest Windows updates is also advisable.

In some cases, disabling Memory Integrity in Windows Security settings may resolve the bhtsddr.sys BSOD error. This feature, designed to protect the core parts of the operating system, may conflict with certain drivers. As a reader, you are encouraged to explore these solutions cautiously.

It is important to note that resolving BSOD errors requires technical expertise. However, you can consider utilizing [d1] PC repair software, a reputable automatic solution adept at handling various issues, including BSODs, registry errors, crashes, and DLL errors. This software can provide a comprehensive diagnostic and resolution approach without requiring intricate manual interventions.

To further troubleshoot the bhtsddr.sys BSOD error, consider checking for any conflicting third-party software or security applications that may interfere with the proper functioning of the BayHubTech SD Reader Driver. Additionally, examining the Windows Event Viewer for specific error logs related to the bhtsddr.sys file can offer valuable insights into the root cause of the issue. 

Fix 1. Updating the BayHubTech SD Reader Driver

Updating the driver can resolve issues caused by outdated or incompatible software. The BayHubTech SD Reader Driver manages the communication between your computer and its SD card reader. An updated driver ensures compatibility with the latest system updates and hardware changes.

• Right-click on Start and pick Device Manager.
• Find and expand the category named Memory Technology Devices.
• Right-click on the BayHubTech SD Reader Driver.
• Select Update Driver.
• Choose Search automatically for driver.
• Follow the on-screen instructions to complete the update.
• Restart your computer after the update.

Note that Windows might not automatically find the latest updates, thus you can either download the driver manually or employ automatic apps such as [rev id="DriverFix"].

Fix 2. Reinstall the BayHubTech SD Reader Driver

Reinstalling the driver can address issues caused by corrupted or incorrectly installed software. This process removes the current driver and replaces it with a fresh installation.

• Open Device Manager via the Start menu.
• Locate Memory Technology Devices and expand it.
• Right-click on the BayHubTech SD Reader Driver.
• Select Uninstall device.
• Confirm any prompts to uninstall the driver.
• Restart your computer.
• Windows should automatically reinstall the driver upon restart. If not, use one of the methods described above to install the newest driver.

Fix 3. Run Windows update

Keeping Windows up to date ensures that your system has the latest security patches and performance improvements, which can sometimes resolve underlying issues causing BSODs.

• Type Updates and press Enter.
• In the new window, click Check for updates.
• Wait till all the files are downloaded and installed.
• If optional updates are available, install them as well.
• Restart your device when done.

Fix 4. Perform SFC and DISM scans

Running both the System File Checker (SFC) and the Deployment Image Servicing and Management (DISM) tool can comprehensively address and repair system file corruption. SFC scans for and repairs corrupted system files, while DISM repairs the Windows system image and resolves issues that SFC cannot fix.

• Type cmd in Windows search.
• Right-click on Command Prompt and pick Run as administrator.
• User Account Control window will show up - click Yes when prompted.
• Then, copy and paste the following command, pressing Enter after:
  sfc /scannow
• Wait till the scan is finished. If Windows finds system file integrity violations, it will attempt to fix them. After this, use the set of the following commands, pressing Enter each time:
  DISM /Online /Cleanup-Image /CheckHealth
  DISM /Online /Cleanup-Image /ScanHealth
  DISM /Online /Cleanup-Image /RestoreHealth
  
• (Note: if you get an error executing this last command, add /Source:C:\RepairSource\Windows /LimitAccess to it and try again).
• Close down the Command Prompt and restart your device.

Fix 5. Check for hard drive corruption by running Check Disk

Hard drive corruption can lead to system instability. Checking the hard drive for errors can help identify and fix issues that might be causing the BSOD.

• Open Command Prompt as administrator.
• In the new window, type in the following command and press Enter after:
  chkdsk c: /f
  (Note: use chkdsk c: /f /r /x command if you are using SSD as your primary partition)
• If you receive an error, type in Y, close down Command Prompt and restart your system.
• Wait until the scan is finished - you can find the results in the Event Viewer.

Fix 6. Restore the system to an earlier point

System Restore can return your system files and settings to an earlier point in time, undoing recent changes that might be causing problems.

• Type Create a restore point in the Windows search bar and open it.
• Click on System Restore.
• In the new window, click Next or Choose a different restore point.
• If available, mark the More restore points checkbox.
• Select the point in time when the issue did not exist and click Next.
• Finally, click Finish.

Fix 7. Disable Memory Integrity

Memory Integrity is a feature in Windows Security that can sometimes conflict with drivers, leading to BSODs. Disabling it might resolve the issue.

• Open Settings.
• Navigate to Update & Security, then to Windows Security.
• Select Device security.
• Scroll down to the Core isolation section.
• Click Core isolation details.
• Under Memory integrity, ensure the switch is set to the OFF position.
