I have a 1TB external hard drive and I decided that I would partition it so I could use one for files and one for Time Machine backups. But I found out that my hdd's partition table is Master Boot Record and I can't transfer the data temporarily on my Mac because the data on it is around 50GB and the free space left on my Mac is 15.67GB. Help!

You need another drive to transfer the files to temporarily.



There are applications which can convert MBR to GUID & then repartition without data loss, for instance Paragon Hard Disk Manager - but a backup is highly recommended anyway...

... so, you need another drive.

    You can use Terminal



    diskutil partitionDisk /dev/disk7 MBR fat32 "NO NAME" 100%


    Replace number 7 on "disk7" with actual disk number..




    • GPT: GUID Partition Table

    • APM: Apple Partition Map

    • MBR: Master Boot Records


    For additional volumes just use this approach



    Volume1Format Volume1Name Volume1Size Volume2Format Volume2Name Volume2Size


    For example:



    diskutil partitionDisk /dev/disk7 MBR fat32 FIRST 100m fat32 SECOND 100m 


    Based on that you are able to make your own command.
