What is Format?
Formatting a drive or device means to prepare some particular part of the device in some different data usage by an operating system by deleting all of the data and all things and setting up the default file system.
I suppose that you might have some questions in your mind. What’s wrong with delete? What’s the difference between deleting and formatting? Frankly speaking, they both are used in the same function. There is no major difference between the two rather they both perform the same task, in different ways. The basic function of both is to erase the present saved data to make room for other data that is required to be saved next by the user. The only difference between the two is that deleting works in a way that one has to delete individual data or select a part of the data that he wants to delete, but the format will delete all the data on the drive or device.
When you delete something, the disk would choose the file or folder and will mark it as an empty space in the file index, while it would be an empty space, some other information can be rewritten on the file. Again, when you format, the disk will erase the index completely and will restore it to its original default empty settings where the disk will be completely empty for rewriting and other usages.
In normal words, if you want to erase some files or one file, you should use the delete facility. But when you want to erase the whole drive or device, it is always a better and faster option to format it. For, formatting takes lesser time than deleting.

Why SD Card won’t Format Showing Error?
It’s true that when an SD card runs into some problems, we normally think to format the card for it to function smoothly again. Sometimes it goes wrong with the file system format while formatting. For example, some devices only understand the FAT32 format, so using others will be error ultimately.

When your SD card is write-protected, you can’t use it like before and that means you are actually in trouble. If your SD card is write-protected, you won’t be able to write new data or save data to the card, can’t delete any files from it or can’t even format it. You see, it is actually a real problem which ultimately means that your SD card in this situation is totally useless.
The write-protection error is a complex error and usually, it’s critical to format write-protected SD cards. Following are some methods to solve them.
- Check the SD card’s exterior carefully. Sometimes there may remain a small switch on one side at the exterior edge of the SD card. If it is there, you should tab in the opposite direction. By changing the position of that switch should turn write protection off and let you format the SD card.
- If the above step fails or if there is no switch on the exterior part of SD card, you might want to check your card properties. Go to My Computer and look for your card reader under Devices with Removable Storage. When you make a right-click on it, you will see Properties option, click it. Sometimes there’s an option to remove write-protection from the SD card. If there is something like that, change this option and try again the formatting.
- If the above two methods don’t work for you, you might want to go for the third and best one. It will definitely work for you. Go to Command Prompt by right clicking on the start button and clicking Command Prompt (admin). Type diskpart and then type list disk. After this, a list of all available disks of your PC will appear on the screen. Remember the number of the disk that is similar to the same size of your SD card. Type select disk m (where m is the number that you have remembered, those are the same size as your SD card).then type attribute disk clear read only. Again type Finally, type exit to exit.
