ERROR_SETMARK_DETECTED - 1103 (0x44F)

A tape access reached the end of a set of files.

Updated: Feb 21, 2026

Technical Meaning

The error code ERROR_SETMARK_DETECTED with the numeric value 1103 and hexadecimal representation 0x44F indicates that a tape access operation has reached the end of a set of files. This typically occurs during operations involving magnetic tape storage systems, where a setmark is used to mark the beginning or end of a file.

Error Details

This error code is specific to tape-based storage and is not commonly encountered in other types of file system operations. It signifies that the tape drive has detected a setmark, which indicates the end of a particular set of files on the tape. This can happen during read or write operations when the drive encounters a setmark.

Usage Context

This error code is relevant to developers and administrators working with tape storage systems. It may be encountered in scenarios where data is being written to or read from magnetic tapes, particularly in environments that require long-term archival of data.

Developer Interpretation

When this error is returned, it indicates that the operation has reached a logical boundary on the tape, specifically the end of a set of files. This can be useful for determining the current position within the tape and managing operations such as file recovery or data integrity checks. Developers should handle this error by ensuring that their applications are capable of interpreting setmarks correctly and adjusting their behavior accordingly.
