Part 2: Format SanDisk SD Card via Built-in Formatting Feature on Windows
Windows provides a quick and simple formatting option. You can use the Quick Formart or Deep Formart feature to remove all your files from your SanDisk SD card. However, this way doesn't support data overwriting.
Here's how to format a SanDisk SD card on a Windows PC::
-
Insert the SD card and open File Explorer by clicking "Win + E".
-
Right-click on the SD card drive under "This PC", and then select "Format..." from the menu.
-
Choose the File System (FAT32 for cards 32GB or smaller, exFAT for 64GB and above). If you want to choose "Deep Format", don't check "Quick Format", and then click "Start".
Part 3: Erase a SanDisk SD Card via Command Prompt
For those who prefer a more hardcore approach or are dealing with a card that won't format via the GUI, Diskpart is the way to go. It can remove partitions and file system errors, and it's very useful when the card becomes unreadable.
To erase a SanDisk memory card with Command Prompt on a PC:
-
Type "cmd" in the Windows Search bar, right-click, and choose "Run as Administrator".
-
Type "diskpart" and press "Enter". Then type "list disk" to identify your SD card's disk number.
-
Input "select disk X" (replace X with your SD card's number, be careful). Finally, type "clean all". This will write zeros to every sector of the card, erasing everything permanently.
Part 4: Formart SandDisk SD Card via Disk Management
If your SD card doesn't show up in File Explorer, Disk Management can help you initialize and format it. Then all the files will be deleted.
Here's how to format a SanDisk SD card with Disk Management:
-
Right-click the "Start" button and select "Disk Management".
-
Locate your SanDisk SD card in the visual list. Then right-click the card and choose "Format" from the menu.
-
Follow the wizard to assign a drive letter and file system.
Part 5: Erase SanDisk SD Card via Disk Utility on Mac
Mac users can format SD cards using the built-in Disk Utility tool, which can erase your memory card easily.

-
Insert the SD card into your Mac computer, and click "Applications" > "Utilities" > "Disk Utility".

Select the SD card in the sidebar, tap on the "Erase" button.
-
Choose a name and format (typically ExFAT for cross-platform compatibility), and click "Erase" to confirm.
Part 6: Q&A About Erasing SanDisk SD Card
Q1: How to make sure a SanDisk SD card is wiped?
To ensure data is unrecoverable:
- Use secure wipe software (e.g., multi-pass overwrite).
- Avoid quick format if data sensitivity is high.
- Verify by attempting data recovery tools afterward.
Q2: Will erasing a SanDisk SD card affect the lifespan of the card?
Yes, but minimally. SD cards use flash memory with limited write/erase cycles. Occasional formatting is normal, but frequent full wipes can contribute to wear. Modern SanDisk cards include wear leveling to extend lifespan.
Q3: Can I remove all the files on my SanDisk SD card when factory resetting my phone?
It depends on the phone:
- Some Android devices offer an option to erase external SD cards during factory reset.
- On most phones, the SD card remains untouched unless you manually format it.
By the way, always back up important data before resetting.
Conclusion
Erasing a SanDisk SD card is a straightforward process, whether you use built-in system tools on Windows and Mac or secure data-wiping software for permanent deletion. If you want to overwrite deleted data permanently with simple clicks, iReaShare Data Wipe can help you. This program can erase your SD card or other storage devices thoroughly.
