Most cameras only perform a "quick format," which leaves your images recoverably intact. Whether you are protecting sensitive client data or trying to revive a glitchy card, sometimes you need a true secure wipe. Here is how to do it properly on a Mac — using tools you likely already have — without risking damage to the card.
UHS-I and UHS-II SD cards have been used in cameras now for several years. And you might have started seeing mentions of UHS-III. So what is it, and should you buy one?
Formatting your SD cards is an essential step to keeping them healthy and the data on them safe. Want to make sure you format SD cards on your Mac the right way? Here's a step-by-step guide for formatting both SD and microSD cards on Mac using two free tools to make sure that the card is ready for use in your camera or device.
A newer, faster version of SD and microSD cards is on the way. They look like existing SD and microSD cards, although they're a lot faster. It might sound like you're getting a faster, better card, but you're almost certainly not (at least, not yet).
That sudden "card is write protected" error on your camera usually comes down to one tiny switch on the SD card's edge. Here's how to spot it, flip it, and what to do if flipping it doesn't fix the problem.
The SD Association puts out their own software for formatting SD and microSD cards and preparing them for use in your camera or device. It's simple to use and reliable. Here's my quick guide to using it.
Seeing A1 or A2 on your next microSD card and wondering if it will make your camera faster? The short answer is: No. While these ratings are a game-changer for the Nintendo Switch, Steam Deck, and smartphones, they work differently than the V-ratings photographers rely on. Here is the plain-English breakdown of what A-ratings actually do and which one you actually need for your device.
UHS-II cards look almost identical to UHS-I ones, but the pins on the back tell you everything. Here's how to spot the difference and know when the faster spec actually matters for your camera.
