ERROR_FLOPPY_WRONG_CYLINDER - 1123 (0x463)
Mismatch between the floppy disk sector ID field and the floppy disk controller track address.
Updated: Feb 21, 2026
Introduction
This article provides a detailed explanation of the ERROR_FLOPPY_WRONG_CYLINDER error code, including its technical meaning and developer interpretation.
Technical Meaning
The ERROR_FLOPPY_WRONG_CYLINDER error indicates that there is a mismatch between the sector ID field in the floppy disk data and the track address reported by the floppy disk controller. This typically occurs during read or write operations on a floppy disk, where the expected cylinder number does not match the actual cylinder number returned by the controller.
Error Details
The error code 1123 (0x463) is specific to issues related to floppy disks and their controllers. It suggests that the data being read or written to a floppy disk does not align with the expected track address, which can lead to data corruption or failure of the operation.
Usage Context
This error code may be encountered in various scenarios where floppy disk operations are performed, such as reading from or writing to a floppy disk. It is particularly relevant when dealing with legacy hardware that uses floppy disks for storage.
Developer Interpretation
Developers should interpret this error as an indication of potential issues with the floppy disk data or controller. The mismatch between the sector ID and track address can be caused by various factors, including incorrect data formatting, hardware failure, or software misconfiguration. Developers are advised to review the operation context and validate parameters before attempting to resolve the issue.

FAQ
Q: What does the ERROR_FLOPPY_WRONG_CYLINDER error mean?
A: It indicates a mismatch between the sector ID field in the floppy disk data and the track address reported by the controller, which can lead to data corruption or failure of the operation.
Q: How can I prevent this error from occurring?
A: Ensure that the floppy disk is properly formatted and that the hardware and software are compatible. Validate parameters before performing operations on the floppy disk.
Summary
The ERROR_FLOPPY_WRONG_CYLINDER error code (1123, 0x463) indicates a mismatch between the sector ID field in the floppy disk data and the track address reported by the controller. This can lead to data corruption or failure of operations on floppy disks. Developers should review operation context and validate parameters to prevent this error.
