Some users want to perform the same operation of Formatting the SD Card or Micro SD Card using the Command Line in Mac OSX  instead of performing it with the Disk Utility.

For example, if  Disk Name  to be given is ‘Traveller‘, the location of the SD card is given as /dev/disk6s2, and you desire the new Format Type to be ‘Mac OS Extended Journaled (JHFS+)‘ then you would write:

diskutil  eraseDisk JHFS+ Emptied / dev / disk6s2

  • Be careful to use the syntax properly, lest you end up erasing the wrong drive or inducing some unfixable error in your SD card. This is why only advanced users use Command Line for Formatting the SD Card on a mac. A much simpler way is using Disk Utility, explained above.
