How to fix “The data area passed to a system call is too small. [ERROR_INSUFFICIENT_BUFFER (0x7A)]” – Error Code 122

Overview

In this article, we’ll focus on resolving the issue described as: “The data area passed to a system call is too small. [ERROR_INSUFFICIENT_BUFFER (0x7A)]”. This error, identified by the error code Error Code 122, can impede your system’s performance, and here’s how you can fix it.

Identifying the Problem

Error Code 122 arises when the buffer allocated for handling data is insufficient to accommodate the amount of data that needs to be processed. This can occur in various contexts, such as:
– Insufficient memory allocation in programming
– Buffer size limitations in file operations
– When using external hardware devices

Common Fixes

1. Restart Your Computer
Often, a simple restart can clear up temporary glitches, including those causing Error Code 122.

2. Check for Memory Leaks
If you’re getting Error Code 122 in programming, check for memory leaks. Use debugging tools or memory profilers to detect and fix memory leaks.

3. Increase Buffer Size
In programming, manually increase the buffer size to accommodate larger data. For file operations, adjust the buffer size parameter to a larger value.

4. Update Device Drivers
Outdated device drivers can cause buffer size issues. Update all outdated drivers, especially those related to storage devices (e.g., hard drives, USB drives).

Advanced Troubleshooting

1. Use a Memory Leak Detector
Employ third-party memory leak detectors such as Valgrind or AddressSanitizer to pinpoint and resolve memory leaks.

2. Check System Event Logs
Examine system event logs for additional information related to Error Code 122. This may provide clues about the root cause of the problem.

3. Perform System File Check (SFC)
Run the System File Checker (SFC) to scan and repair corrupted system files. In the command prompt, type: sfc /scannow

Conclusion

By following these solutions, you should be able to resolve Error Code 122 effectively. Remember to apply these fixes promptly to avoid further system performance issues. Regular system maintenance, including memory leak checks and device driver updates, can help prevent this error in the future.
