摘要：
A hybrid drive is disclosed comprising a head actuated over a disk comprising a plurality of data tracks, and a non-volatile semiconductor memory (NVSM) comprising a plurality of memory segments. When a life remaining of the NVSM falls below a threshold, the NVSM is marked as read only. When a write command is received from a host including write data, and when the NVSM is marked as read only, the write data is written to the disk and a corresponding memory segment in the NVSM is invalidated.
