Abstract
Zone Write Groups (ZWGs) to assist data storage devices and host devices with data recovery. In one embodiment, a data storage device includes a memory storing a Zoned NameSpace (ZNS). The ZNS includes a ZWG including host zones and parity zones. An interface connects the data storage device with a host device. The data storage device includes a data storage device controller including an electronic processor and a memory. The data storage device controller populates the ZWG with buffers received from the host device. The data storage device controller detects corrupted data associated with the ZNS and requests one or more buffers stored in the ZWG. Once the data storage device controller receives the one or more buffers from the ZWG, the data storage device controller performs a recovery event with the one or more buffers.
