Purpose of the Guide

Help format an SD or TF card so it can work in the correct format for CCTV devices using a MAC. This can solve problems where the card is not recognised by the devise. 


Before you Begin

Make sure you have your card ready and your MAC has a compatible slot or card reader available. 



Background

SD cards with a capacity of 64GB or greater will allow you to record for the longest time possible. However using a 64GB or above card isn’t a case of just putting the card in like with smaller SD cards. 64GB and 128GB cards require formatting FAT32 before they will work in your recorder. 


There are a couple of recommendations we have when using a 64GB/128GB card.


Double check your unit will support 64GB or 128GB, as the maximum for many cameras is 32GB.


We recommend using Class 10 or above speed SD cards.

We recommend using a reputable brand from a reputable seller. We sell cards that have been tested with our equipment.


Don’t use a Class 4 SD card. They’ll probably be too slow and cause corruptions of your recordings.

If the card you’ve bought seems to cheap to be true, it’s probably a fake and won’t last very long, if it works at all. This is the most common cause for issues with our SD card based units. 


Let's Get Started

As mentioned at the beginning of the article we’ll now need to format the SD card in your Mac Computer.

The first step is to connect the SD card to your Mac. You can do this using the built in card reader if you have one. If you don’t have a built in card reader then in most cases you can put the card in the device you want to use it in, then connected that device to your Mac via USB. If the device you’re wanting to use the card in can’t be connected to a PC then you’ll need a dedicated card reader. There are a number of card readers available, just make sure it’s compatible with SDXC cards, otherwise it might not work with a 64GB card.


Once the SD card is connected to your Mac you’ll need to open the Disk Utility. This is easily done by clicking the spotlight icon in the top right of your screen (or by pressing the keyboard shortcut cmd + spacebar) and searching for Disk Utility.

Click on Disk Utility to launch it and you’ll get something like this:

First select the SD card from the list on the left hand side. In this example we’re formatting a 4GB card, but the process is identical for formatting a 64GB card. Be sure you’re selecting the correct drive.

 Next click the Erase option highlighted in the image above by a orange box.

 Now click the Format drop down and select MS-DOS (FAT). You can also add a name to make the card easier to identify in the future.

 

The final step will erase the entire contents of the SD card. Be sure you have the correct drive selected and that any required data from the SD card is backed up before proceeding.

Finally click the Erase… button to start the formatting process. 


That's it! Once the erase process is finished the card is ready to be used in your recorder.
