Scenario

“My Kingston 4GB flash drive was working fine for two years but after formatting it suddenly became inaccessible and requires formatting and gets popups that your USB is write protected and Windows cannot format it. Is there a Kingston USB format tool to force format the write protected Kingston USB drive? I would like to make the flash drive functional again, please give me solution. Any help is appreciated!”

Why format (Kingston) USB drive?

Nowadays, USB flash drive are widely used in our daily life. But sometimes you will be noticed that your USB flash drive needs formatting Some of you may puzzled that why format USB drive? The common reasons are as follows:

Cause various operating systems must manage disks in a certain way, only the corresponding format (namely,file system) can make the structure of the disk be recognized by the operating system. For example, Windows and Apple systems have different disk management methods and are not compatible with each other. Or some device only support specified file system. So you must format your storage drive to the suitable file system.

When you buy a new USB flash drive without being formatted, you must format it at first. After that, you can use it normally. Or when the USB drive is attacked by virus, formatting the drive is also an effective way to eliminate viruses. Moreover, if your USB flash drive becomes write protected or read only, formatting also helps you with that.

Format Kingston USB flash drive with Windows built-in tool

If you cannot format Kingston USB flash drive via Disk Management or Windows Explorer, it’s time to resort to another Windows built-in tool: DiskPart, a command to help manage your PC's drives (disks, partitions, volumes, or virtual hard disks). The specific steps are as follow:

1. Press “Windows” + “R” to open the Run box, type “diskpart” in the run dialogue, and then hit “Enter”.

2. In the pop-up window, input the following commands and hit “Enter” after each command.

  • list disk

  • select disk n (here “n” is the disk number of USB drive.)

  • list partition

  • select partition m (here “m” is the number of partition going to be formatted.)

  • format fs=fat32 (here if you need to format the Kingston USB drive to other file system like exFAT, replace the command with “format fs=exfat”.)

Format via Diskpart

Note: if the Kingston USB drive is set into read only (write protected) mode, you need to first remove the read only attribute by running the command “attributes disk clear readonly” after select disk#.

Here I strongly recommend AOMEI Partition Assistant Standard.
