Abstract
Implementations of the present disclosure relate to a method and apparatus for handling an error for a drive. The logic space of the drive is divided into a plurality of extents. The method comprises determining a type of errors in response to the errors detected in I/O operations for the drive. The method further comprises determining a drive extent of the plurality of extents of the drive that causes the errors in response to determining that the type of the errors is a soft medium error or a data error, the soft medium error being an error that can be repaired by re-mapping of a failed extent and the data error being an error that is caused by damage of data on the drive. Furthermore, the errors can be handled only with respect to the drive extent that causes the errors.
