MacOS Disk Utility is perhaps one of the most overlooked and underused programs on a MacOS computer. But it is extremely helpful, as you will soon see. One of the best features is being able to reformat a USB stick, a SD card, or even an entire hard-drive at the click of a button.
There are many reasons why you would want, or would need, to reformat something. I can think of three off the top of my head.
That means once a USB stick or a SD card is formatted for say Microsoft Windows, you will have some difficulties with it on another operating system. For example, I cannot delete files on a Windows-formatted USB stick if I put it into my Mac.
So you may want to format something to another operating system format.
If your computer has been hit by a serious virus, or is just generally under-performing, reformatting may be your only option. Reformatting your hard drive will wipe it completely, and you would then need to reinstall the operating system.
You should also do this, if you are selling your computer. If you do not reformat your hard drive, deleted files can be recovered by the new owner, if they have the right software. If those files are extremely sensitive (social security number, bank records, etc), then that is obviously not good for you. Activision update modern warfare.
Before reformatting your hard drive, make sure all of your files are backed up in a secure separate location. But not the operating system files obviously!
When I recently received a SD card from a friend with some holiday photos on it, I had the 'show hidden files' option ticked in Windows Explorer. Not for the purposes of the SD card – I merely forgot to switch it off earlier.
So when I put the SD card into the computer, up popped all the hidden files which my friend thought were deleted. Now and then movie trailer. The actual files were not readable, but the file titles were. They were of the adult variety, so imagine his horror and embarrassment.
When you delete a file, the crap 'temp files' are left behind. They take up space, but they can't be seen unless you have the option on to view them. Reformatting will nuke them all for good.
Disk Utility is inside the Utilities sub-folder of the Applications folder. When you start it up, it will look like this.
On the left are all of the hard drives and removable devices that Disk Utility can detect. If you don't see something here, eject it then re-insert it. It should then pop up in the list.
The SD card I will be reformatting today is TOM (the other one is JERRY, get it?). TOM has had some sensitive work files on it, so I want to reformat the card and destroy any chance of the files being recovered by some dastardly dude later.
Before I do this though, it is worth quickly going through the other macOS Disk Utility features, in case you are not familiar with them.
Straightforward to understand. This gives you information about the media you have highlighted.
This will safely eject the removable media from the computer, identical to the 'eject' function in the Windows right-click menu. Once it has been unmounted, the button will rename itself to 'mount'. Press that to start up the removable device again.
As the screenshot below shows, 'Restore' will erase everything on the highlighted device and you can have the contents of another connected device copied over.
'Partition' allows you to take a hard-drive and split it up into sections. This is invaluable if you are an Apple beta tester, and you want to put the beta OS on a separate area of your computer.
Simply choose the hard-drive from the list on the left, and click 'partition'. Name your partition, choose the format (make sure it is for MacOS), and the size you want it to be. Disk Utility will do the rest.
In a nutshell, 'First Aid' checks and repairs file system errors on the removable media you have highlighted. If you get strange error messages, or your computer is crashing frequently, then run First Aid to see if it can diagnose the problem.
With a hard-drive however, 'First Aid' will lock the hard-drive while it is being checked. This means all other programs will be non-responsive. Just a warning in advance!
Now we finally come to the meat of the article – erasing and reformatting a removable media device. In this case, a SD card.
When you click the 'Erase' button, you will be given the opportunity to change the name of the card, as well as choose its format. Unless you have a very special reason for doing so, do NOT change the format it is currently on.
If you click on the 'Security Options' button at the bottom, you will be able to specify how tough the reformatting should be. On the least end of the scale is this :
As it says, it is the fastest method of reformatting but you are not going to securely erase them. The files may still be recoverable. So you need to start moving the slider along until you get to something you are comfortable with.
The furthest end of the scale is this and is the hardcore option :
This is bad-ass level. You will be erasing media at the same level as the US Pentagon, by going over the data 7 times. But this comes with a warning. 7 times takes a very….very….long….time. I am now at two and a half hours and counting, and we are only on Pass 2! Extreme security comes at a very high price, including laptop battery!
The crappy thing is that once it starts, it is impossible to stop. You could pull the card out, but you risk damaging it. So be very careful if you decide to go down that route. We don't recommend it.
As I said before, Microsoft Windows comes with a reformatting option, which lives in the Explorer right-click menu. But I really like MacOS Disk Utility, for the fact that everything is concentrated in the one interface. For me, it's user-friendly, and hard to mess up. Just my kind of program!

SD cards are the ultimate little lifesavers in extending the storage space on your smart devices. But, you'll need to format an SD card on your Mac before you can use it.
We'll take a look at the steps needed to do this, so you can get back to work. http://ahhnieq.xtgem.com/Blog/__xtblog_entry/19266728-blue-penguin-business-card-designer-2-61-download-free#xt_blog. The steps are pretty simple, and require just your SD card and the Disk Utility app. Luckily, Disk Utility is already included with macOS.

These ultra-tiny flash memory cards are used primarily for extra iPhone and camera storage. It's important to note that you will want to back up any of the files that are already on your SD card. After the formatting process is completed, the card will be completely wiped clean and the files will be deleted.
Once your SD or micro SD card has been backed up, you will be ready to format the storage device. Here are the steps to make it happen:
After you have pressed the Erase button in Disk Utility, the app will ask you to rename the SD card. Do this, and then tap the Erase button in the bottom right-hand corner.
Additionally, there is a section that asks you which format you want the SD card to be formatted in. We recommend switching this format option to ExFAT if it's not already selected.
From here, Disk Utility will work its magic and will format your SD card. Once it is completed, you will want to press the 'Done' button in the bottom right-hand corner.
Now, you might be a bit excited to have this finished, but don't just go pulling out the SD card yet. Instead, find the formatted card in the sidebar on the left and press the eject button. Doing so will ensure that something doesn't get broken, which will usually need a reformat before the card will properly work again.
After Apple decided to redesign the MacBook Pro lineup in 2016, this meant the death of the SD card slot. Most MacBook models previous to this iteration have the slot built into the side, but if not you'll need an extra piece.
Depending on which version of the Mac you own, you will need to get a USB SD card reader. These are relatively inexpensive, again, depending on which model Mac you are trying to use this with.
After you have completed the steps above, your SD card will be wiped clean, and can then be used for any application that you seem fit. Whether that's to use it in a digital camera, build a Raspberry Pi system, or any other project that you want to complete.
If you run into issues, let us know in the comments below, and we'll be sure to help figure out what's going on. This is a pretty straightforward process, but you'll need to follow the steps correctly, as Disk Utility can also wipe other connected hard drives.
