You just got off the computer store with an 8gigabyte Raspberry Pi. You pay no mind to the size because you have a spare 64gigabyte SD card at home. You install the card on the hardware and it has refused to boot. You were not prepared for this, were you? How do you get this SD card to work? What are the special requirements for Raspberry Pi SD cards?

This article will guide you as to why you need to format your SD card, The Raspberry Pi SD card format, Raspberry Pi SD card size and most interestingly, how to format or reformat an SD card for a Raspberry Pi. Let's dive in, shall we?

Part 1. Do You Need to Format SD Card for Raspberry Pi?

The Raspberry Pi is a group of small boarded computers that were made majorly for teaching basic computer science in learning institutions. They have been in existence since 2012 and have since then gained relevance in other fields such as research, robotics & Artificial Intelligence, and Climatology. The Raspberry Pi became very popular for its portability and because it is inexpensive.

Due to its peculiar nature, it also possesses some special features to make it work. The SD card used in the Raspberry Pi is one of them. These SD cards should be of special formats and sizes to prevent any irregularities in the performance of the machine. We'll look through these special features as we go on below.

Raspberry Pi SD Card Format

Today, there are 3 major formats of SD cards. They are the FAT16, FAT32, and exFAT formats. Each format represents classes of SD cards based on specifications provided by the SD association. The FAT16 format is found in SD cards and their capacities are from 128Mb to 2Gb of data. The FAT32 on the other hand is found in SD High Capacity (SDHC) cards and can take information between 4Gb to 32Gb. The last format, exFAT, is found in SD Extended Capacity (SDXC) cards. These cards can take data ranging from 64Gb to 1Tb.

The Raspberry Pi's bootloader can only read from FAT16 and FAT32 SD cards. Thus, if you have any SD card with capacities higher than 32Gb, you have to format or reformat such SD card to FAT32 before installing on your Raspberry Pi. Now that you know the format, Let's talk about size.

Raspberry Pi SD Card size

SD cards have evolved from time. As we have come of age, we have seen a lot of doubling in sizes and capacities of these cards. Currently, we have SD cards of 128Mb, 256Mb, 512Mb, 1Gb, 2Gb, 4Gb, 8Gb, 16Gb, 32Gb, 64Gb, 128Gb, 256Gb, 512Gb, 1Tb and most recently 2Tb. The earlier sizes (2Gb and below) have lost relevance as requirements for them have reduced over time. The 2Tb SD card is still the most recent one and thus, very scarce.

The Raspberry Pi comes with an 8Gb SD card installed. It's great if you are not a constant user of the computer. If you are, then you'll be getting the "Low Disk Space" warning soon. This is why most Raspberry Pi users use SD cards with a higher capacity. Cards with capacities greater than 32Gb have been found to work fine, if properly formatted (As you'll learn in this article).

Before you go to the next step, it is important to keep a backup of important files and documents on the SD Card before formatting or reformatting the card. RecoverIt is a great tool for recovering lost files on a drive or SD Card.

click ok and wait

Your FAT32 SD Card is now ready to be used on your Raspberry Pi.

Method 3. Diskpart to Format Your SD Card

DISKPART (short for Disk Partition Tool) is a tool found in windows Operating systems for managing computer drives and partitions.

To use the diskpart method to format your SD card for your Raspberry Pi, follow the steps below.

Step 1. Run Diskpart as administrator. This can be done by opening "Run" from the start menu, typing "diskpart" and clicking "OK".

Step 2. Enter "ListDisk" to list disks available on the system

Step 3. Enter "Select disk x" where x is the number corresponding to your disk

Step 4. Enter "List Partition" to create a list partition on the SD Card

Step 5. Enter "select partition x" where x is the same number of the SD card as in step 3

Step 6. Finally, enter "format fs=fat32 quick" and wait for the program to run to 100% completion as seen below.

When the process is complete, the SD Card is ready to be used on a Raspberry Pi.

If your SD Card is higher than 32Gb, you can use the Powershell to format it into the FAT32 type.

Method 4. Powershell Method For 64gb And 128gb SD Cards

This method takes quite some time to complete due to the volume of the cards involved.

To do this, follow the steps below;

Step 1. Enter the Windows button and "X" simultaneously and click on "Powershell (Admin)" from the menu to run Powershell as an administrator.

windows + x then click Powershell(admin)

Step 2. Type "format /FS:FAT32 X:" into the command box and press enter. The card begins to be formatted and once completed in an hour or so, the SD Card is ready for use on the Raspberry Pi.

Part 5. Tips on Making an SD Card for Raspberry Pi

There are some important tips to take note of when making an SD Card for your Raspberry Pi. This is key to prevent loss of data and to ensure that the formatting process is as efficient as possible.

1. Be patient and careful

See all the instructions above, you don't want to make a mistake on any one of them and end up formatting a wrong disk drive. This is why you must not rush when performing any of the processes above. You must also ensure that your computer is well charged or connected to a power source when any formatting process is ongoing. This is to prevent the corruption of the SD Card as a result of the system going off.

2. Always back up your files

If the SD card you're looking to format is a new one, you have little to worry about when it comes to backing up. If it has been in use before now, then you have to pay attention to the files on it. Formatting an SD card will lead to erasing all of the files on it. This is why you should back up by making copies on the cloud, on a separate drive/disk, or on your computer.

3. How to recover lost files

Accidents happen. It could have been an error, or even deliberately but we can end up losing key files. You need not worry. They're not gone forever! Recoverit is a fast, effective, and easy to use Recovery tool that gets your files back in less than 5 minutes!

Your files can be regained in these easy steps;
