An SD card or a Security Digital card is one that is going to store additional amounts of information for you. It’s used for mobile devices such as cameras and smartphones, for instance, and it’s capable of being a lifesaver in certain situations.
However, the type of SD cards that the majority of phones and other mobile solutions like tablets, for instance, are going to use the so-called micro SD card. What is a micro SD card? You might ask. This is basically a slightly smaller SD card which is going to be about the size of your fingernail. However, unlike their appearance, these little helpers are capable of storing up to several gigabytes of information.
The same goes for the size of the card. You wouldn’t want to spend a couple of hundred bucks to get a 120 GB card when in reality you wouldn’t use more than, let’s say 10GB. With this in mind, you would also want to get an answer to the question of what is an SD card used for.
The SD card is a basic way of transferring information and storing it. The good thing about it is that it’s a non-volatile solution just like the majority of storage devices and you don’t need a power source for it to keep the data. Furthermore, it’s particularly portable and mobile and a regular micro SD card is going to be compatible with a wide range of mobile devices, provided they accept the implementation of an SD card.
You’d be surprised to understand that a lot of manufacturers would allow customers to implement a micro SD or a regular SD card. The reason is pretty obvious – they want to force people into purchasing their highest-paid product if they need more space.
How to use the SD card?To be completely honest, the usage of an SD card is pretty straightforward. In any case, all you need to do is pick out the SD slot from the device that you want to use it with, place the card within that slot and insert it back into the device.
Usually, the device is going to automatically pick up the signals and it’s going to deploy all the necessary information on its own so there’s really no need for you to do anything.
How to reformat the SD card on Mac?
- Connect the SD card to your computer by using an external card reader. Save all the files from your SD card that you want to keep to your computer before moving to step 2. Formatting the SD card deletes all the data off of the card.
Also note – Mac OS 10.6.5 or earlier does not support exFAT format, which most 64 GB SD cards are formatted to. This means that you won't be able to format or use an exFAT card on your computer. In this case, we'd recommend either upgrading your OS to 10.6.6 or later, or using an SD card that's already formatted to MS-DOS (FAT) or FAT32 to complete the below steps.
- Open Disk Utility. To do this, click on the magnifying glass in the top-right corner of your computer screen. Type “disk utility” in the search box that opens, then click on the “Disk Utility” Application that comes up.
- Find the SD card on the left side of the window. It’ll be named something like NO NAME or UNTITLED.
- Click the ERASE tab in the middle of the window.
- Next, click on the Format dropdown menu. Select MS-DOS (FAT) if the card is 32 GB or smaller. If it’s a 64GB card, please select ExFAT.
- A message will appear asking, “Are you sure you want to erase the partition “[YOUR SD CARD NAME]?” Click Erase. The computer will delete the contents of your SD card and format it. You’re all done.
So basically that’s the process that you’d have to go through if you use the SD Card Formatter. It goes without saying that it’s pretty seamless and easy to use. However, it might help if you have some basic ideas and knowledge on what is an SD card and the specifications around it. This way you can manage everything a bit better.
However, it’s also safe to say that the software doesn’t presume any technical knowledge so even if you have nothing to do with computers it’s easy to recover your information through it. Losing information could be detrimental in certain situations and it is software such as SD Formatter that could turn out to be life-saving.
