Abstract

A drive disk that includes the system and method for locating sectors. That skips around In which both checkers that are not working And checkers that are reserved Map address display The accepted logic is converted to the position of the corresponding logic diagram by determining the position of the table. The first table includes the entry for the true track, which then joins the LBAs into a group of bits. In high order shared The second table contains an entry for a checker that skips high-order LBA bits that are assigned to be used to select the entry in Table One which entry will be. Index into the second table Starting from the index point, the second table is searched. Using the LBA low-order bit for checkters that are skipped out of the LBA value, when the appropriate skipped checkter is found, the index of this skipped checkter within the second table is added to the LBA to calculate the PBA. After that, the PBA is assigned to the zone, cylinder, head, checkter position on the drive disk.The positioning system reduces all the storage required to convert LBAs to ZCHS and improves functionality. Of the conversion process Additional characteristics will include the third table. For separating broken checkters from backup checks. And a plan for determining Duplicate which checkers are reserved To replace the erroneous data checker during use and the overlap between high-order LBA and low-bit beam to further improve performance.
