ERROR_SECTOR_NOT_FOUND
The requested physical area was unavailable
ERROR_SECTOR_NOT_FOUND means the drive or controller could not access a requested sector. It can result from media damage, a failing device, stale geometry assumptions, corrupted partition metadata, or an operation directed at the wrong raw device.
Investigation steps
- Determine whether the caller uses a filesystem path or raw disk offsets.
- Inspect storage-health data and controller event messages.
- Validate partition boundaries, image size, and sector-size assumptions.
- Avoid repeated destructive writes to an unstable disk.
Recovery considerations
For ordinary files, copy recoverable data to healthy storage and restore the damaged content from backup. For raw-disk utilities, recheck every offset calculation, especially 512-byte versus 4K-sector handling. Persistent occurrences usually require media replacement or specialist recovery rather than application-level retries.
