Abstract
Physical subsector error marking allows for selectively marking subsectors of a physical sector of a storage medium as unreadable. The error marking may include a bad sector mask to indicate that the subsector is unreadable combined with an error signature to confirm that the bad sector mask was set intentionally. The remaining readable subsectors of the physical sector may be returned to the host.
