Abstract
The present disclosure generally relates to creating and recalibrating zone groups. Rather than having a fixed zone group size, the zone group size can be dynamic where the data storage device provides a range of zone group sizes to a host device. Based upon block availability and host device commands, new zone groups may be formed of different sizes within the provided range. If there is an insufficient number of blocks available to create a zone group with a size within the provided range, the data storage device can recalibrate. The insufficient number of blocks may be due to bad blocks and/or fragmentation. To obtain more blocks, garbage collection can occur and/or the data storage device can request the host device to release some blocks. The dynamic zone group creation and recalibration ensures more efficient operation of the data storage device.
