How and Why Should I Reformat My Memory Card?

When it comes to cybersecurity, the risk associated with SD memory cards is underestimated, mainly due to the overwhelming number of benefits. Memory cards don’t have moving parts—they’re light, compact, easily portable, and can be used without a power connection. They don’t require maintenance or updates, they’re available in a wide range of sizes, and they’re a great backup tool for various devices (i.e. smartphones, car cameras, and computers). However, memory cards have some vulnerabilities.

The more data you amass on a memory card, the less reliable it is. Though a memory card’s primary function is to save and backup loads of important files, the risk of losing those files increases greatly as your card reaches full capacity. Furthermore, some memory cards contain firmware. In most cases, firmware updates will never be activated. However, the possibility exists, and in rare instances, your card could be altered to create more space, save copies of your files, and even store malicious software in hidden spots—all without your knowledge. The best way to combat these risks is by reformatting your memory card.

Why should I reformat my memory card?

Typically, you delete or erase files from your memory card when you want to free up space. However, deleting or erasing a file doesn’t necessarily remove it. Instead, your card will simply write over the “deleted” files whenever you save new data. This means the “deleted” files remain on the card until they’ve been replaced. Reformatting is a more thorough security measure that ensures you permanently erase all the data before adding new files or images. It’s the only way to rest assured that a file is truly erased.

How should I reformat my memory card?

Reformatting your memory card is a relatively simple process but varies based on your operating system. But, before you get started, there are a few preparation steps and helpful reminders to consider:

• Back up any images or files that are valuable. Once you’ve reformatted your card, you won’t be able to retrieve them.
• Reformat your cards on a regular basis, as a protection for your devices and your data.
• If a memory card has been problematic in the past, don’t bother with reformatting. Simply purchase a new card.
• Format all new cards before you use them.
