Format is the operation of initializing a disk or partition within a disk, which usually results in all files in the existing disk or partition being erased. Formatting is usually divided into low-level formatting and high-level formatting. Unless otherwise specified, formatting a hard disk is usually referred to as advanced formatting, while formatting a floppy disk usually includes both.
Advanced formatting, also known as logical formatting, refers to an operation that writes specific data to a specific area of the disk according to the file system selected by the user (such as FAT12, FAT16, FAT32, NTFS, EXT2, EXT3, etc.) to initialize the disk or disk partition and clear all files in the original disk or disk partition.
Advanced formatting includes rewriting the corresponding area of the partition table in the master boot record, and setting aside a piece of disk space in the partition for file management, such as file allocation tables and table of contents, according to the file system selected by the user, so that the user can use the partition to manage files.

4Rebuild the partition table and fix the SD card that cannot be formatted. Some SD cards are recognizable on a computer, but cannot be read or written. When using the built-in formatting tool of Windows, the "file system is raw" is displayed when formatting, and the formatting cannot be completed.
SD card repair tools such as mformat, portfree, etc., will not help it either. What should we do when we encounter this kind of failure?
5 First of all, the faulty equipment can be identified by the system, which is usually a software failure, and the software failure can usually be repaired by using some tools and software. It's a pity that some users have sentenced SD cards that can be recognized by the system but cannot be formatted.
6 We know that when the partition table of the hard drive is corrupted, the formatting cannot be done either. In this case, you can use the partition tool FDISK that comes with Windows to rebuild the partition table. This idea of solving hard disk failures can also be used on SD cards, but the specific methods are slightly different.
Step 1: Insert the SD card into the computer and turn it on. Right-click on the "My Computer" icon and select "Manage", and the "Computer Management" window appears.
Step 2: Click on "Disk Management" under "Storage" on the left side of the window, and the screen will show the information of all storage devices in the current system. Disk 1 (removable) is the SD card to be repaired.
Step 3: Point to Disk 1, right-click, select New Partition, and then select FAT32 or NTFS, the system will prompt that the partition has been created successfully.
Step 4: Format the SD card.
With the above mentioned steps, the SD card can be repaired.
