I'm following the instructions in Creating a bootable Clonezilla dual partition USB device but using my Mac laptop running El-Capitan.
I managed to create an MBR partition table and two partitions on the external USB drive using OSX'
fdisk utility but I failed to find a way to format the existing partitions to ExFAT.
All the references I found so far point to
diskutil eraseDisk or suggest using Windows or Linux for that, but I don't have access to bare-iron servers with these OS's and failed to access the unformatted USB drive from VirtualBox virtual machines on my laptop.
So, the question is - "Is there a way to execute the equivalent of
mkfs.vfat -F 32 /dev/sdb1 on OS X?"
