    摘要: Apparatuses and methods for redirecting data writes are disclosed. In one embodiment a controller may be configured to receive a command including write data and address data identifying a target zone of a data storage medium; determine whether the target zone contains sufficient available data sectors to store the write data; and record the write data to a common area of a different zone when the target zone does not contain sufficient available data sectors, the common area available to store data when a target zone lacks sufficient available data sectors. In another embodiment, a method may comprise receiving a write command identifying a target zone of a data storage medium; determining whether the target zone contains sufficient available data sectors to store the write data; and recording the write data to a common area of a different zone when the target zone does not contain sufficient available data sectors.
