Formatting an SD card and why it may not work

Why format your drive?

Formatting is used to prepare the drive for operation or troubleshoot problems. If the SD card is new, then formatting will allow you to create a new file system table layout, sometimes selecting a suitable file system. For previously used drives, formatting will allow you to recreate the file system table, restore or hide unreadable damaged memory cells.

SD memory card formatting is also used:

  • to completely delete information without the possibility of recovery;
  • to configure the file system;
  • recovery from failures or viruses when the drive does not allow reading or writing information;
  • to create several local partitions, or combine partitions into one disk.

Why might the SD card not be formatted?

There are several reasons why the SD card will not format:

  1. Antivirus is active. The antivirus always pays close attention to devices connected to the computer. Namely, it scans the drive for malicious code. When scanning occurs, the program reads information from the SD card, and during reading, no files can be erased. Before carrying out the operation, it is recommended to temporarily disable the antivirus.
  2. Operating system. Its scanners can also read information from a flash drive. Before clearing data, it is recommended to end processes that use the SD drive.
  3. SD card malfunction. There is a possibility that it simply fell into disrepair.

Method 3: formatting with third-party programs

To format a memory card you will need a computer, a card reader and, optionally, an adapter for MicroSD. In this case, specialized programs are used to work with the drive: MiniTool Partition Wizard, SD Formatter, EzRecover, etc.

The operating principle of the programs is relatively the same, only the capabilities of formatting and servicing the drive differ: low-level formatting, complete deletion of data without the possibility of recovery, recovery from software failures, etc.

Advantages

The programs allow you to perform several types of formatting, restore data, or restore the drive's functionality. The utilities also offer to select and configure the file system type, set the drive size, etc.

Flaws

Some programs are limited in capabilities, are available for a fee, or only work with certain types of drives. Most programs only support English localization. Also, do not forget about the need for a computer and a high-quality card reader.

What utilities can you use to format USB drives and memory cards?

If standard cleaning methods do not help, then you can format the flash drive with programs that will help you completely clean any storage media. The best software for this are:

  1. HP USB Disk Storage Format Tool is a utility developed by Hewlett-Packard. Initially, it was used on devices released by this company. The design of the application is similar to the standard system one; it can format flash drives in NTFS, FAT, FAT32 formats. To work, you must connect a flash drive or card reader via port 2.0. The utility can be used to prepare the use of multiple memory on smartphones, as well as to create bootable disks. The program is distributed free of charge.
  2. HDD Low Level Format Tool is a program for returning flash drives to their factory state. Using it, you can not only format a memory card, but also fill the device’s memory with so-called zero bytes. The disadvantage of the program is that it is in English. But nevertheless, the program interface is as intuitive as possible; you can get complete information about the media and format it. The utility even allows you to remove viruses from it.
  3. SDFormatter is another popular utility that allows you to delete all information on memory cards. It is also suitable for regular flash drives. But it is best to use it specifically for SD media. It is designed taking into account the specifics of memory cards used in cameras, players and smartphones. The utility uses special formatting methods; it helps even in cases where standard tools cannot remove all information from the media. The interface will not cause any difficulties even for a person who does not own a computer. When formatting, it is best to select the Full (Earse) option, then the cleaning will be the most complete.
  4. AutoFormat Tool is a utility with a user-friendly interface. There is nothing superfluous in it, only formatting. You need to run the program as an administrator, since it can work not only with removable media, but also with the hard drives of the PC itself. The only difficulty in using the program is that you need to correctly specify the path to the desired volume in the Disk Drive section. If you accidentally confuse a letter, you will format the wrong media, be careful.

All these programs are distributed free of charge. Experienced users can also try using another tool on their PC - the command line and special software. This will allow you to format the flash drive and save information on it. This is the most unusual way of working with media.
