Detailed Description

Optional auxiliary fragments accompanying a raw sector dump.

Sector tags preserve on-disk / on-media structures that are not part of the main user data (sync/header/ECC, etc.). They enable exact reconstruction, verification or advanced analysis (error injection, subchannel decoding, etc.). Retrieval APIs generally expose presence queries and raw byte buffers of fixed size (unless documented as string).
