SD Card Formatter: What Is It?

An SD card formatter is a tool used to format an SD card, microSD card, SDHC card, or SDXC card. It can erase existing data, change the file system, or prepare a memory card for use with a computer or other device.

For Windows users, you can format an SD card with File Explorer, Disk Management, or DiskPart. MiniTool Partition Wizard provides another option when you need additional partition and file system management features.

# 2. Built-in SD Card Formatter – Disk Management

Disk Management is a built-in Windows utility that enables you to create, delete, shrink, and format volumes, as well as assign or change drive letters.

Windows Disk Management typically offers NTFS, FAT, FAT32, and exFAT options. The available options may depend on the card capacity, the existing partition, and your Windows version.

Step 1. Run “diskmgmt.msc” at CMD. Then the Disk Management utility will appear. Find the SD card you want to format and then select “Format…” from the right-click menu.

Step 2. In the format window, customize the volume label, file system, and allocation unit size, choose whether to perform a quick format and enable folder compression, then click “OK“.

Step 3. Disk Management sends out a warning message which reads “Formatting this volume will erase all data on it. Back up any data you want to keep before formatting. Do you want to continue?” Now click “OK” to format memory card/SD card, which should be finished in a minute if the quick format is selected.

# 3. Optional SD Card Formatter – Windows Explorer

You may also find that there is a “Format…” option when you right-click the partition in Windows Explorer. Yes, this also helps you to format memory card/SD card. And all things you need to do are:

Step 1. Select “Format…” from the GUI of the right click menu.

Step 2. Then you can choose the file system & allocation unit size, enter a volume label, select quick format and then hit “Start” button.

Step 3. Finally, a warning message saying “Formatting will erase ALL data on this disk. To format the disk, click OK. To quit, click “CANCEL”. Click “OK” to confirm formatting the SD card.

# 4. Optional SD Card Formatter – Diskpart

Diskpart is the last solution that we can resort to. Why do we place it at the end? Well, because it requires putting some commands before memory card format is finally carried out. Here is the process you need to go through if you want to format an SD card.

Step 1. Run diskpart and confirm you want to allow this app to make changes to your PC.

Step 2. In the command shell, type the following commands in order, and make sure each command is ended up with Enter key.

• list disk
• select disk n where n is the disk number that represents the SD card to be formatted
• list par
• select par n where n is the partition number of the SD partition
• format fs=ntfs quick OR format fs=fat32 quick
• exit

In this case, you should make sure that the SD card is not physically locked by the movable button at first. If the SD card is not physically locked, you should try to find the solutions to remove write-protection. We think our previous post “How to Remove Write Protected Error” may be helpful to you.

Step 2. Install and launch this data recovery product. 

Step 3. Select the best data recovery module.

Why Do You Need to Format an SD Card

Formatting creates a new file system on the card and removes the existing file records. It may be necessary in the following situations:

• To Delete Files: when you want to clean the data on the SDHC/SDXC memory card, you can format the SD card directly.
• To Change File System: in order to use the SD card on multiple personal computers and devices, you will need to use the appointed file systems. For example, to increase the internal storage space of Android, you need to format the first SD card partition with FAT32, and the second partition with EXT file system. To successfully read and write in Mac OS X, you are suggested to choose FAT file system.
• To Fix Issues: sometimes, when you try to access the SD card which has a RAW file system, Windows asks you to format it before you can use it. Similarly, if Windows reports “The Disk Structure Is Corrupted and Unreadable“, formatting is always the right solution.
• To Kill Viruses: if the SD card is infected by viruses, formatting is a good trying to remove the viruses for security purpose.

Which File System Should You Choose

NTFS is the best choice for internal hard drives — it’s more powerful and safer than FAT or FAT32, but has more limited support outside Windows.

FAT32 remains the most broadly compatible option for cameras, consoles, and other removable-media devices, at the cost of a 4GB single-file limit. exFAT is a good middle ground when you need large files and modern device support. FAT16 is essentially legacy and rarely the right choice today.

Conclusion

An SD card formatter can help you format an SD card, SDHC card, SDXC card, or microSD card on Windows. You can use Windows File Explorer, Disk Management, or DiskPart, or use MiniTool Partition Wizard when you need additional partition management features.

Before formatting, back up or recover important data and make sure you choose a file system that is compatible with the device where the SD card will be used.
