Abstract
A method of retrieving storage capacity of damaged sector. A storage medium comprising a storage capacity part and a reserved capacity part is provided. The storage capacity part comprises multiple primary sectors, while the reserved capacity part comprises multiple secondary sectors. The storage medium is scanned to find and record a damaged sector in the storage capacity part. An identity field of the damaged sector is overwritten by an null identity field of one of the secondary sectors. The identity field of the damaged sector is written into the secondary sector.
Claims9
A method of retrieving a capacity occupied by a damaged sector of a storage medium, comprising:
- scanning the storage medium to record an identity tag of the damaged sector;
- overwriting the identity tag of the damaged sector with a null identity tag of a reserved capacity sector;
- and
- overwriting the null identity tag of the reserved capacity sector with the identity tag of damaged sector.
A method of retrieving a capacity of a damaged sector, comprising:
- providing a storage medium comprising a storage capacity part and a reserved capacity part, wherein the storage capacity part comprises a plurality of primary sectors and the reserved capacity part comprises a plurality of secondary sectors, and each of the primary sectors has a corresponding identity field and each of the sectors has a “0” identity field;
- scanning the primary sectors to find a damaged primary sector and to record a corresponding identity field of the damaged primary sector;
- overwriting the corresponding identity field of the damaged primary sector with one of the “0” identity field of one of the secondary sectors;
- overwriting the “0” identity field of the secondary sector with the corresponding identity field of the damaged sector;
- and
- rearranging an output sequence of the identity fields of the primary sectors.

- scanning the primary sectors to find a damaged primary sector and to record a corresponding identity field of the damaged primary sector;
- writing a zero identity field to the damaged primary sector;
- and
- writing identity fields to the primary sectors and one of the secondary sector with the damaged sector being skipped, and writing a zero identity field to the rest of the secondary sectors.
