Abstract
Described herein are systems, methods, and software to manage metadata in a data storage device. In one example, a data storage device includes a first storage zone, a shingled magnetic recording (SMR) zone, and a storage control system. The storage control system is configured to maintain metadata in a metadata location of the first storage zone for user data in the SMR zone. The storage control system is further configured to, responsive to a usage condition being satisfied for the metadata in the metadata location, identify metadata locations in the SMR zone to redirect and store the metadata. The storage control system is also configured to maintain an indirection data structure in the metadata location of the first zone that correlates the metadata locations in the SMR zone to the metadata.
