# diskutil partitionDisk
> Utility to manage partitions inside disks and volumes.
> Part of `diskutil`.
> APM is only supported for macOS, MBR is optimized for DOS, while GPT is compatible for most modern systems.
> More information: <https://keith.github.io/xcode-man-pages/diskutil.8.html>.
- Reformat a volume using APM/MBR/GPT partitioning scheme, leaving no partitions inside (this will erase all data on the volume):
`diskutil partitionDisk {{/dev/disk_device}} 0 {{APM|MBR|GPT}}`
- Reformat a volume, then create a single partition using a specific filesystem filling up all free space:
`diskutil partitionDisk {{/dev/disk_device}} 1 {{APM|MBR|GPT}} {{partition_filesystem}} {{partition_name}}`
- Reformat a volume, then create a single partition using a specific filesystem under specific size (e.g. `16G` for 16GB or `50%` to fill half of total volume size):
`diskutil partitionDisk {{/dev/disk_device}} 1 {{APM|MBR|GPT}} {{partition_filesystem}} {{partition_name}} {{partition_size}}`
- Reformat a volume, then create multiple partitions:
`diskutil partitionDisk {{/dev/disk_device}} {{number_of_partitions}} {{APM|MBR|GPT}} {{partition_filesystem1}} {{partition_name1}} {{partition_size1}} {{partition_filesystem2}} {{partition_name2}} {{partition_size2}} ...`
- List all supported file systems for partitioning:
`diskutil listFilesystems`
