Some of the most fundamental SD cards or SDHC cards are compatible with almost all the relevant devices. Many of the devices that are compatible with just SD card have to use only SD card for booting. But most of the devices have their higher end compatibility with SDXC and SDHC cards.

To unmount the drive type; SUDO UMOUNT DISK2
To unmount the subpartitions type; SUDO DISKUTIL UMOUNT DISK2p1.
To make the SD card bootable type in; SUDO DD Bs=4m if= image_name.xyz of dev/disk2
