How to Format Volumes as NTFS or EXT using macOS Terminal

The final commands should be modified appropriate to your disk and partition. Enter:

diskutil list

Check the number of disk and partition. Then X and Y in diskXsY parameters in commands from further steps must be replaced with appropriate values (for example disk2s1)

Format:

First it is required to unmount volume with

sudo diskutil unmount diskXsY

Then format the partition:

sudo diskutil eraseVolume "<filesystem>" "LABEL" /dev/diskXsY

or format the whole disk:

sudo diskutil eraseDisk "<filesystem>" "LABEL" /dev/diskX

Possible values for <filesystem>:
UFSD_NTFS - Windows NT File System*
UFSD_EXTFS - Linux Extended File System 2**
UFSD_EXTFS3 - Linux Extended File System 3**
UFSD_EXTFS4 - Linux Extended File System 4**

* requires NTFS for Mac
** requires extFS for Mac

"LABEL" - specify volume label.

To change partition table format, please add the following value after "LABEL":
GPTFormat - GUID Partition Table
MBRFormat - Master Boot Record
APMFormat - Apple Partition Map
OS9Drivers - Apple Partition Map (for Mac OS 9)

To verify the volume:

diskutil verifyVolume /dev/diskXsY

To repair the volume:

diskutil repairVolume /dev/diskXsY
