The attempted operation required self healing to be enabled.
Updated: Feb 21, 2026
Technical Meaning
The ERROR_DISK_REPAIR_DISABLED error code, with the numeric value of 780 and the hexadecimal representation of 0x30C, indicates that a specific operation attempted on a disk required self-healing to be enabled. Self-healing refers to mechanisms within Windows designed to automatically repair certain types of file system errors without user intervention.
Error Details
This error typically occurs when an operation is initiated that necessitates the presence of self-healing features, such as those provided by the chkdsk utility or other disk maintenance tools. If these features are disabled, the operation cannot proceed and this error code is returned to indicate the failure.
Usage Context
This error can be encountered in various scenarios where disk integrity checks or repairs are required. For example, attempting to run a disk check using chkdsk with the /f (fix) option when self-healing is disabled will result in this error being returned.
Developer Interpretation
Developers should interpret this error as an indication that the operation attempted cannot proceed due to the absence of necessary self-healing mechanisms. This can be addressed by enabling self-healing features or ensuring that the operation does not require them if they are not available.
