Sometimes when formatting the SD card, there is a failure or error that prevents you from finishing or performing the formatting. Even if you cannot change the drive under warranty, do not rush to throw it away. Our article will offer you 3 solutions to fix problems with formatting SD and microSD cards.

Method 1: Formatting in the Disk Management utility

Formatting is not possible if all processes and operations are not completed on the map. In this case, the standard formatting method will not work — the system will report that the disk is busy. You need to use the built-in Windows Disk Management utility.

Instruction

Tap the Start button, and then enter diskmgmt. msc in the search. Or, in the control panel, open the System and Security section, and then select Create and Format Hard Disk Partitions.

A list of connected drives will appear in a new window. You need to select the connected SD card, open the context menu with the right mouse button and select the Format… action.

In the new window, select the Formatting Options, and confirm the action.

Important! Malicious programs often interfere with formatting. Scan the drive for viruses.

Method 2: formatting in third-party programs

Programs designed for the purpose of formatting storage devices offer more features than standard utilities in Windows. Some applications, the HDD Low Level Format Tool or MiniTool Partition Wizard, allow you to perform low-level formatting of the flash drive to completely delete the recorded information.

Third-party programs for formatting flash drives often help format cards that were previously used in DVRs or other equipment. The main problem of such drives is protection against overwriting. Therefore, only complete deep, so-called low-level formatting usually helps to restore the performance.

The simplest program for formatting is SD Memory Card Formatter, developed by the SD Association. The utility will automatically find SD drives, which will allow you not to worry about erroneous deletion from hard drives. And in the program window, you only need to select the type of formatting – Fast or Full.

Another useful program is the MiniTool Partition Wizard. The utility supports fast, full, and low-level formatting. It also includes tools for detecting and eliminating errors.

To check for errors, select Check File System in the left panel.

Method 3: Formatting in proprietary utilities

SD card manufacturers have appropriate programs for formatting or restoring the drive. Applications are usually distributed free of charge and without additional conditions. Visit the manufacturer’s official website to find the appropriate program.
