After a blue screen occurs, if dump file creation fails despite correct settings, you can find this event in Event Viewer: Event ID 161, Source volmgr;
Dump file creation failed due to error during dump creation. BugCheckProgress: 0x00040049
This event indicates that the hard disk's I/O operation did not respond within the timeout period;
What is volmgr
volmgr is Windows' volume manager component. It is responsible for managing hard disks, partitions, and volumes, and handles low-level disk read/write requests. When it reports errors, it typically indicates a serious disk access problem.
Problem Causes
Most likely, the blue screen was caused by hard disk failure (disk drop-out). Event 161 indicates that the system failed during I/O operations to write memory data to disk (creating dump file);
This is a serious hardware-level error, possible causes include:
Hard Disk Failure
The hard disk may have bad sectors, controller failure, disk drop-out, or be near complete failure;
Some hard disk firmware may have defects that cause failures under specific conditions (such as attempting to extract very large files);
Data Cable or Hard Disk Interface Connection Issues
Interfaces may be loose or aged, causing unstable signal transmission;
Insufficient Power Supply
Unstable power supply during high disk load operations;
Solutions
This event is a clear hardware failure warning signal; you should immediately back up important data.
If blue screens continue during data backup, seek professional assistance to prevent complete disk inaccessibility and total data loss.
Check Hard Disk Health Status
We recommend using the free software CrystalDiskInfo, which you can install via Microsoft Store;
Any red warning items confirm hardware failure, and you need to replace the hard disk.
Troubleshoot Interfaces
After powering off, reseat the hard disk connections; if the motherboard provides other hard disk interfaces, try using a different interface;
