Abstract: A slide seat adjusting device for adjusting positional relation between a slide seat and a base, comprises a pair of identical adjusting blocks each having an abutting surface and a slant surface opposite the abutting surface. The slant surfaces of the pair of adjusting blocks abut against each other and have identical gradient values, the pair of adjusting blocks are slideably disposed between the slide seat and the base, the abutting surface of one of the pair of adjusting blocks abuts against the slide seat in a surface-to-surface manner, the abutting surface of another one of the pair of adjusting blocks abuts against the base in a surface-to-surface manner, and the abutting surfaces of the pair of adjusting blocks are parallel to each other.

Abstract: An automatic process for recovering bad disk sectors by providing improved error handling and recovery of data, maintains disk data consistency, and relocates data structures from bad disk sectors. A bad-sector-mapping (BSM) table to correspond to a reserve sector space in the disk. In one embodiment, the BSM includes N entries for N reserved sectors in the bottom space of a disk. The content of each table entry contains two fields: a header and an address. There are three flag bits being defined in a head field, with each flag bit being used to specify status of how a bad sector occurred. The address field stores a disk offset for identifying the location of data stored in the disk. The last entry of the map table, or the last n+1 entry, is a checksum entry.
