STATUS_NONEXISTENT_SECTOR
The requested sector address is outside the medium layout
The controller or media format could not locate the addressed sector. This can result from an out-of-range LBA, stale geometry after media replacement, damaged sector-identification fields, or a request built for a different format.
Validate the request offset and length against current media capacity before assuming physical damage. If the address is valid, preserve low-level error details and attempt read-only recovery; repeated writes or formatting can destroy evidence. On floppy media, track, head, and sector identifiers are especially important.
What to inspect
- Record logical address, transfer length, current geometry, and media-change generation.
- Confirm the sector lies within the recognized partition or tape block range.
- Use read-only recovery and hardware diagnostics when a valid address cannot be located.
