ERROR_DIRECT_ACCESS_HANDLE - 130 (0x82)
Attempt to use a file handle to an open disk partition for an operation other than raw disk I/O.
Updated: Feb 21, 2026
Technical Background
ERROR_DIRECT_ACCESS_HANDLE is a specific error code in the Windows operating system, with the numeric value 130 and the hexadecimal representation 0x82. This error indicates an attempt to perform an operation on a file handle that refers to an open disk partition using methods other than raw disk I/O.
Error Details
The error is generated when a developer or a system attempts to use a file handle, which was opened for direct access to a disk partition, in a context where only raw disk I/O operations are allowed. Direct access handles are typically used for low-level disk operations that bypass the normal file system layer.
Common Causes
- Incorrect Object Type: The operation being attempted is not compatible with the type of object represented by the handle (e.g., trying to perform a file read/write operation on a direct access handle).
- Invalid Parameter Values: Parameters passed to the I/O operation are invalid or do not align with the expected usage context.
Real-World Context
This error typically occurs in scenarios where low-level disk operations are required, such as when working directly with partitions for tasks like data recovery, partition management, or custom file system implementations. Developers must ensure that they use the correct type of handle and operation for their intended purpose to avoid this error.
Is This Error Critical?
Yes, this error can be critical if it occurs during operations where disk integrity is paramount. It may indicate a misuse of resources or incorrect handling of file handles, which could lead to data corruption or system instability.
How to Diagnose
- Review Operation Context: Ensure that the operation being performed aligns with the type of handle used (e.g., direct access vs. normal file handle).
- Validate Parameters: Check all parameters passed to I/O operations for validity and correctness.
- Confirm Object Types: Verify that the object types match the expected usage context.
- Verify Input Data: Ensure that input data is valid and appropriate for the operation being performed.
- Check Limits or Constraints: Confirm that no system limits have been exceeded, such as maximum number of open handles.
How to Resolve
- Correct Parameter Usage: Use parameters that are compatible with the type of handle (e.g., direct access).
- Adjust Operation Context: Ensure that operations are performed in an appropriate context where they can be executed without error.
- Restore Data: If data corruption is suspected, restore from a backup or use recovery tools to repair the affected files or partitions.
- Retry Operation with Valid Inputs: Attempt the operation again using valid and correctly formatted inputs.
Developer Notes
Developers should be aware of the specific requirements for direct access handles and ensure that their code adheres to these constraints. Misuse can lead to system instability, data corruption, or other critical issues.
Related Errors
ERROR_INVALID_PARAMETER(120): Occurs when an invalid parameter is passed to a function.ERROR_ACCESS_DENIED(5) : Indicates that the requested access is not allowed for this object.ERROR_DISK_FULL(76): Occurs when there is insufficient disk space to complete the operation.
FAQ
Q: What does ERROR_DIRECT_ACCESS_HANDLE mean?
A: It indicates an attempt to use a direct access handle in an inappropriate context, such as performing file read/write operations on a partition that was opened for raw I/O.
Q: How can this error be avoided?
A: Ensure that the correct type of handle is used for the intended operation and validate all parameters before executing I/O operations.
Summary
ERROR_DIRECT_ACCESS_HANDLE is a specific Windows API error code indicating an attempt to use a direct access handle in an inappropriate context. Developers must ensure proper usage of file handles and understand the constraints associated with direct access to avoid this error.
