Overview of SD Cards

SD cards, also known as Secure Digital cards, are a popular type of memory card used in various devices such as digital cameras, smartphones, and more. You will find various SD cards in the market. These cards include SD, SDHC, and SDXC. Each of them comes with different speeds and capacities. SD and SDHC cards need to be updated because they have slow transfer speeds and limited capacities. However, SDXC cards have much faster transfer speeds. They have a storage capacity of up to 2TB, which makes them a preferred option for professional photographers and videographers. It is important to remember that not all devices are compatible with every SD card. Therefore, it is crucial to check your device's specifications before buying a new SD card.

Things You Should Do First 

Formatting an SD card is an important step in managing your digital files, particularly when using it with a MacBook Pro. But before you format an SD memory card on your Mac, there are some important steps you should follow to make sure everything goes smoothly. Here are the initial tasks you should complete:

1) Check the File System Compatibility:

It is important to note that not all file systems are compatible with all operating systems. You have to check if the SD card is compatible with your Mac. For example, Mac versions older than 10.6.6 (Snow Leopard) do not support the exFAT file system. Therefore, you need to check the file system compatibility before formatting the SD card. You can check the manufacturer's instructions or website for more information if you need more clarification. Moreover, if your Mac doesn't have a built-in SDXC card reader, make sure you have a suitable SD card reader and cable to transfer files and photos at maximum speed and ensure faster formatting.

2) Remove Write Protection: 

If you find that you are unable to format the SD card, it may be write-protected. Some SD cards come with a physical switch that you can slide to remove write protection. Therefore, make sure to check if your SD card has this switch.

Please choose the Correct Name: It is essential to choose the correct name of your SD card in Disk Utility or Mac Terminal. It is easy to get confused when you have multiple external devices attached to your MacBook Pro. Therefore, take your time to confirm that you are selecting the correct device name before proceeding with the formatting process.

3) Backup Your Data: 

Formatting an SD card erases all data on the device. Therefore, before formatting, ensure that you have a backup of all the necessary files and documents stored on the card.

What to Do After Formatting Your SD Card on Mac?

Once you have formatted your SD card on a Mac, it is crucial to follow some additional steps to make sure your data is secure and ready for use. Here are some suggestions to consider:

1) Verifying the Card Was Formatted Correctly:

Before using the card, make sure that the formatting process is successful. To check if the card is recognized, insert it into your camera or phone. If it is not acknowledged or functioning correctly, you might have to reformat it once more.

2) Scanning for Any Errors:

It is recommended to scan your SD card for errors after formatting, as formatting can sometimes reveal issues with the card. You can accomplish this on a Mac using the "Disk Utility" application. To start scanning, open the app and choose your SD card. Then, click on "First Aid."

3) Safely Remove the Card:

After ensuring that your card is functioning correctly, you can safely detach it from your computer. On a Mac computer, it is important to properly remove a card by either dragging it to the trash or clicking the eject icon in the Finder. That will stop any loss or damage to the data.

4) Considering a Backup Solution:

It is possible to move saved images back to your memory card, but this is usually not advised for non-professional photographers. Instead, it is recommended to store your data on multiple devices or consider using a backup solution such as an external hard drive or cloud storage.

Other Ways to Format an SD Card on Mac

In addition to the previously mentioned quick method, there are several other ways to format an SD card on a Mac. Although the built-in tools are simple to use, they may only sometimes be the most efficient. Here are two additional methods for formatting your SD card on a Mac:

Way 1: Format SD Card on Mac Via SD Card Formatter

The SD Card Formatter is a useful tool for quickly and easily formatting your SD card on a Mac. It is easy to use, saves time, and automatically chooses the right file system format, removing the need for any complex manual setup. Follow these easy steps to clear your SD card on a Mac and prepare it for your next project:

1) Download the SD Card Formatter

You can download the SD Card Formatter for free from the SD Association website. It works on both Mac and PC and can easily format different types of SD cards.

2) Connecting Your SD Card to Your Mac.

If your Mac has a built-in SD card slot, you are able to connect your SD card directly. But if your Mac doesn't have a built-in card slot, you will have to use a card reader to connect it to your computer.

3) Start the SD Card Formatter

After connecting your SD card to your Mac, launch the SD Card Formatter application. The app will detect the SD card that is connected and show its details.

4) Select Your Formatting Options

The SD Card Formatter is an easy-to-use application with a basic interface and few controls. You don't have to select a file format because the app will automatically choose the appropriate file system for formatting your SD card based on its size. Click on the 'Format' button, and the application will start formatting your SD card.

5) Waiting for Process Completion

Using the command line interface to format an SD card allows the user to have more control over how the formatting is done. The user has the option to select the type of file system and make other formatting choices using straightforward commands. While using the visual interface may be simpler, this approach provides additional features for performing more advanced formatting tasks. Here is a simple way to format your SD card using the command line:

1) Connect the SD Card to the Mac and Open the Terminal.

If you cannot find the Terminal app on your Mac, you can also navigate to it using the Finder window. You can find it at Applications > Utilities > Terminal.

2) View Connected Drives on Mac with diskutil list

Enter "$ diskutil list" in the Terminal and hit Enter. That will open the list of drives connected to your Mac. Next, identify your SD card from the list displayed.

3) Using the "diskutil reformat" Command

Type in the command "$ diskutil reformat disk2," but make sure to replace "disk2" with the name of your SD card. This command will reformat your SD card without changing the current file system. Please be aware that when the formatting process is finished, all the data that was previously saved on the SD card will be completely deleted.

4) Select the New File System

Type the following command in the Terminal: "diskutil eraseDisk FAT32 MBRFormat /dev/disk2". Make sure to replace "dev" with the appropriate location of your SD card. This command will change the file system of your SD card to a different format. You can choose a different file system by replacing "FAT32" with another format like "exFAT" or "MacOS Extended."

5) Verify the Success of the Process

After finishing the formatting process, open the Terminal and type "$ diskutil list" to confirm that the SD card has been successfully formatted.
