About Bad Sector Retest
- Use Bad Sector Retest to check sectors on FAT and FAT32 partitions that have been marked bad and recover sectors that are usable.
The FAT file system allocates disk space for file storage in units called clusters, which are composed of a fixed number of sectors. Because the FAT file system tracks bad sectors at the cluster level, it marks an entire cluster bad even though the problem may exist in a single sector. Use the Info option to discover whether a partition contains bad clusters. For more information, click See Also on the Help toolbar.
As a conservative measure, when you move or resize a partition or increase cluster size, PartitionMagic marks all new clusters containing any part of old bad clusters as bad (even though the clusters may not actually contain bad sectors). Likewise, when you decrease a partition's cluster size, PartitionMagic divides bad clusters into multiple bad clusters. If, after you complete these tasks, PartitionMagic reports bad sectors, you can perform Bad Sector Retest and reclaim the good sectors that were marked bad.
You should be aware that some sectors marked as bad are "marginally bad," meaning that one time the sector works fine and another time it does not. Bad Sector Retest may mark a marginally bad sector as good. This can result in data loss if the marginally bad sector fails in the future. Most modern hard drives detect bad sectors and automatically remap the sector, so in general, you do not see bad sectors on modern hard drives. If you do get bad sector errors on a modern hard drive, it is recommended that you replace the drive.
