Bad Pool Header with error code 0X00000019 either refers to the stop errors or the BSOD (Blue Screen of Death) that happens when there is an issue with memory allocation in Windows OS. The issue can be due to the failure of a storage device or if the driver corrupts. It can occur due to bad sectors and other issues associated with the hard drives. In certain cases, it may occur due to RAM errors.

The system displays a Stop Error or BSOD to ensure the OS is not affected by hardware or software failure. It acts as a safety measure and can happen without sending any prior notification. A BSOD error usually occurs due to hardware failure while using the systems. The hardware is responsible for storing Windows OS. The issues with the hardware may occur due to aging or if it is physically damaged. If the hard drive and RAM are damaged, it can also have a Bad Pool Header. It can occur due to corrupt drivers or if the system is missing system files.

If this error occurs, it is usually harmful to the file you are currently using or working on- It could be a Word file, a video, or some important documents the user edited. The system files get corrupted, or the system cannot locate the files. The error may also occur if the user changes the files or the files no longer exist in the system. It can create problems, leading to file system errors or corrupting the device.

How to Save Your Data

It can be difficult to retrieve the data from the hard drive as no guaranteed solution can save the data that can be used in all scenarios that may cause bad pool header errors. There are some steps that the user may follow if the error occurs due to a hard drive having bad sectors. Bad sectors refer to the physical location in the hard drive where the data is neither written nor read. Here are steps if you wish to recover data from a hard drive:

Be Prepared

  • Backup: Since the system does not provide any prior warning before the Bad Pool Header error. Therefore, backing up the drive before recovering the data is better. It ensures the user keeps the entire data if the data recovery fails.
  • External Enclosure: If you can still use the hard drive but the system fails to read it because of bad sectors, then you should place the hard drive in an external enclosure. It might be possible to access the hard drive with a different system.

Using Data Recovery Software

  • Data Recovery Software: The user can use software for the data if the hard drive has bad sectors. Some of these software are Recuva and EaseUS Data Recovery Wizard.
  • Scan the Drive: Running a scan on the hard drive is recommended before using data recovery to find and recover the files. The software may enable the system to work around the bad sectors and read the data from the readable data.

Clone the Drive:

Hard Disk Cloning: If there are any bad sectors in the hard disk, the user should consider creating a clone or disk image of the drive tools like ddrescue. When cloning a hard disk, the data is copied bit by bit. It skips the bad sectors. The user can work on the clone instead of the original drive.

Call Professional

Data Recovery Services: if the data stored in the system is valuable and the above steps fail to recover the data. Then, it is better to take the help of a professional to perform data recovery. They have specialized tools and knowledge that make them more suitable to deal with such scenarios, including bad sectors.

Last Option

Freezing the Device: In some cases, people were able to temporarily resolve the issue by keeping the hard drive in an airtight bag and freezing it for a couple of hours. It causes the metal equipment of the hard drive to contract, and the user might be able to use the drive for a brief period.

Replace the Electronic Components: It may be possible that the bad sectors are caused in the hard drive because of malfunctioning in the device electronics. Then, it can be corrected by replacing the electronic component of the drive. The user can change the PCB (circuit board) of the drive. However, it isn't easy and needs expertise.


Once you have saved the data stored on the hard drive, you can move to the next step, resolving the error. Below are the steps to fix the BAD POOL HEADER 0x00000019 error.

Disconnect External Drives and Devices

If the system crashes, then you should immediately unplug all the USB devices attached to the system. Keep the mouse and the keyboard connected to the computer and try to restart the system. Use the normal settings to start the PC, and if an external device causes the problem, the system will no longer show the BAD POOL HEADER BSOD error. Once the system starts functioning normally, try connecting the USB devices one at a time. It will enable you to determine which device is responsible for the error. You can replace the device to resolve the error once you find the device.

Check Drive SMART Data

Suppose the hard disks or the storage device were purchased recently. In that case, you can use the Self-Monitoring Analysis and Reporting technology to ensure the storage device works properly. It monitors the storage device based on critical parameters such as the Reallocated Sector Count and Current Pending Sector Count that can lead to a BAD POOL HEADER.

You can use different utilities such as Drive Monitor to monitor the SMART status of your storage drive. The utility will show the current condition of the drive based on the parameter attributes RAW value.

Scan Disk for Bad Sectors

The most common cause of BAD POOL HEADER error is if the drive has bad sectors. When using the hard drive's SMART status, you should look for any warning sign other than the Reallocated Sector Count attribute. If it shows any other warning, the user should replace the drive, which can cause future errors. It can fail due to the unavailability of space sectors that are used to reallocate the bad sectors.

There are some instances when there are no warnings; the user should check the drive for bad sectors to ensure the drive condition visually. To check, you must first use the Drive Monitor utility.

Follow the below steps. It requires additional data recovery software. Below, we have used Stellar Data Recovery software.

  1. You can download the software from the official website. Install and run the software.
  2. Click on Monitor Drive and then select Scan Disk.
  3. In the next step, choose the hard drive you want to run the Scan. All the drives connected will be displayed in the top right. Select the drive and then click on Scan.
  4. Once the Scan is completed, if you see several red blocks, it is advisable to change the hard disk. Create a backup of the data to ensure data is safe even if the error occurs. After the Scan, if you see too many red blocks, you must replace the hard drive to fix the error. Proceed to step 8 to change the drive without losing data or OS configuration. If you don't want to replace the entire drive, try a low-level format to reassess the bad sectors.

Test RAM

If the RAM malfunctions, the system can also have a BAD POOL HEADER 0x00000019 error. So, to ensure that the RAM is functioning properly, the user can either use the Windows RAM Diagnostic tool or a third-party application testing tool.

Follow the below steps to perform monitor RAM using the Windows Memory Diagnostic Tool:

  1. Use the Windows+S shortcut to open the search bar. Type Memory Diagnostic and click on Windows Memory Diagnostic to open the utility.
  2. Before running the diagnostic, close all the running applications, including any application running in the background, then select Restart Now and check for problems.
  3. To fix issues with the RAM, try switching the RAM to a different slot in the PC motherboard. If there is no issue with the RAM, you can proceed to the next fix.

Check and Update Device Drivers

If the drivers are not updated regularly, then it can cause hardware errors. Drivers act as a link between the hardware and the operating system. If the OS cannot communicate with the hardware due to corrupt drivers, then the OS may crash to safeguard other essential components of the system from damage.

Follow the below procedure to perform an update or reinstall the drivers:

  1. Turn on the computer. It is advised to start the system in Safe Mode.
