One embodiment described herein provides a method and system for handling errors in a storage system. During operation a data-placement module of the storage system detects an error occurring at a first physical location within the storage system. In response to determining that the error occurs during a write access, the system writes to-be-written data into a second physical location within the storage system, and updates a mapping between a logical address and a physical address associated with the to-be-written data.
