3.5.1 Using ImageWriter (graphical interface).

3.4.1 Run an App (Only with graphical interface).

3.4 Flashing the SD card using Mac OS X.

3.3.2 Using flashnul (if Win32DiskImager isn't successful).

3.3.1 Using the Win32DiskImager program.

We will now again use this command to verify the sd card with ‘verifyVolume’. You are now already aware the diskutil command is capable of quite powerful actions. We can still execute another command to confirm the disk is in good health.

You should now already see the SD card is restored completed: you were able to reclame the full capacity of the external flash storage. Validate to ensure you have reclaimed the disk space Example output when instructing Terminal to list all the disks connected to your Mac device (both internal disks and external disks). This command will then continue and format your SD card to FAT32 file system type and rename it to ‘SDCARD’ (you can rename to something else).

This command will execute as ‘sudo’, meaning you will likely have to enter your password to continue. Sudo diskutil eraseDisk FAT32 SDCARD MBRFormat /dev/disk2

STEP 4: Now we will fully erase the disk by using the eraseDisk command.

We will now go to the 4th step, assuming that your device is also listed as ‘ disk2‘ in the diskutil overview. dev/disk2 (external, physical):Ġ: FDisk_partition_scheme *128.0 GB disk2 And in our case, it is clear from the output there are multiple partitions present. Typically you will notice that your SD card shows up as /dev/disk2.

This command will list all your internal and external storage devices. Paste the following text in Terminal and press ENTER You can find it in the Utilities folder, or use via Spotlight search. Make sure your SD card is properly connected to your Mac computer. This means all data will be erased, so only do this when you are sure the data is no longer meaningful to you. Note: the following instructions below will effectively format your sd card. It is a powerful tool to execute commands: in this case we will be using the diskutil command. We will use Terminal to get back the missing storage space on your SD. This solution should work for any type of file system (exFat, FAT32, NTFS, …) by the way. Yet, it also has its limitations because it cannot always recognise hidden partitions on a flash drive such in our case the SD card (this can be any type of SD card: SD, SDHC, SDXC and SDUC, and microSD, microSDHC, microSDXC and microSDUC). The Disk Utility is a great tool for simple tasks related to disk management (such as checking the health of an external hard drive disk and potentially repairing any issues).

Solution: How to reclaim SD card full storage capacity may think your SD card is corrupt or malfunctioning. If you tried to format the SD card yourself already, it will only format the first partition (because it is the only one it can ‘see’). This is the partition you want to reclaim. Partition 2: this is a hidden partition and is not shown when opening the Disk Utility on macOS.This is what I was seeing and worried me, because it is a lot smaller than the original 128 Gigabyte total storage it had when I bought it. Partition 1: this is the boot partition and in my case it was about 60MB in size.Upon flashing an operating system / image to an SD card, the SD card is divided into two partitions. Why is my SD card not showing its full capacity? And this method should work perfectly fine for SSD disks as well. This seemed strange to me as the total capacity was 128GB! Luckily in the end I found how to restore an SD card to its full capacity. Unfortunately, when I plugged in the SD card into my Macbook, I noticed there was only a small number of Megabytes as total storage. As such, I wanted to repurpose the Raspberry: remove HomeBridge from the SD card and add Home Assistant instead. While it was a great learning experience, I now wanted to try Home Assistant to control my smart home. Earlier this year, I had been flashing the HomeBridge image on an SD card to use it together with a Raspberry Pi.
