ERROR_BAD_DEVICE_PATH - 330 (0x14A)
An attempt was made to send down the command via an invalid path to the target device.
Updated: Feb 21, 2026
Technical Background
The ERROR_BAD_DEVICE_PATH error code, with a numeric value of 330 and a hexadecimal representation of 0x14A, indicates that an attempt was made to send a command via an invalid path to the target device. This error is typically encountered when there are issues with the specified device path in API calls or system operations.
Error Details
The ERROR_BAD_DEVICE_PATH error occurs when the operating system detects an issue with the device path provided for a specific operation. The device path can be part of various system commands, such as file I/O operations, device configuration, or other low-level system interactions. This error is indicative that the specified path does not conform to the expected format or structure required by the API or system.
Common Causes
- Invalid Path Format: The provided device path may contain incorrect characters or syntax that do not adhere to the expected format for the operation.
- Incorrect Object Type: The object type specified in the path might be inappropriate for the intended operation. For example, attempting to access a file as if it were a directory.
Real-World Context
This error can occur in various scenarios where device paths are used, such as when mounting volumes, accessing files, or configuring hardware devices through system APIs. Developers should ensure that the paths they provide are correctly formatted and appropriate for the intended operation to avoid this error.
Is This Error Critical?
The criticality of this error depends on the context in which it occurs. While not necessarily a catastrophic failure, it can prevent certain operations from completing successfully, leading to potential data loss or system instability if left unaddressed.
How to Diagnose
To diagnose ERROR_BAD_DEVICE_PATH, developers should:
- Review Operation Context: Ensure that the operation context is correct and appropriate for the device path provided.
- Validate Parameters: Verify that all parameters, including the device path, are correctly formatted and valid.
- Confirm Object Types: Confirm that the object types specified in the path match the expected types for the intended operation.
How to Resolve
To resolve ERROR_BAD_DEVICE_PATH, developers should:
- Correct Parameter Usage: Ensure that all parameters, including the device path, are correctly formatted and valid.
- Adjust Operation Context: Verify that the operation context is appropriate for the specified device path. If necessary, adjust the context or use a different path.
Developer Notes
Developers should be cautious when constructing device paths to ensure they conform to the expected format and structure required by the system APIs. This can help prevent ERROR_BAD_DEVICE_PATH errors and ensure smooth operation of their applications.
Related Errors
- ERROR_PATH_NOT_FOUND: Occurs when a specified path does not exist.
- ERROR_INVALID_PARAMETER: Indicates that one or more parameters passed to an API are invalid.
FAQ
Q: What causes ERROR_BAD_DEVICE_PATH?
A: This error typically occurs due to incorrect device paths, such as invalid characters or syntax, or mismatched object types for the intended operation.
Q: How can I prevent this error?
A: Ensure that all device paths are correctly formatted and appropriate for the intended operation. Validate parameters before making API calls.
Summary
ERROR_BAD_DEVICE_PATH is a specific error code indicating an issue with the device path provided in system operations. Developers should ensure correct parameter usage, validate inputs, and adjust context as necessary to avoid this error.
