Hello There,
I'm came with a useful and Remedy to recover your virus infected or Dual partitioned hidden or any kind of problems You find on your Hard disk drive as well as pen drive External removable storage devices.

You can easily follow these simple steps and recover your drive to its old stage by using WINDOWS
Here I'm using Disk Management in Windows Machine and also Microsoft DiskPart version 6.2.9200
Unfortunately Windows does not support Fdisk or GParted such as… anymore. But there is another good command line tool to solve this problem. The tool’s name is DiskPart. I would say it is the next generation of Fdisk tool. DiskPart provides you information about your partitions and volumes allow you to delete and create partitions, extend NTFS volumes, etc.

Let’s remove unallocated space. First of all run Windows command line By Running cmd.exe in RUN menu
and Windows will ask you for Administrator permissions to run the tool. Or please RUN cmd.exe by Administrative Privilege
Type Diskpart in the command prompt(CMD).
Windows will ask you for Administrator permissions to run the tool.
Then run list disk command to find your USB flash disk’s number. It should be the same as disk’s number in Computer Management tool. It was 1 in my case. Next you should chose the disk to work with.
Type select disk <disk number> command, e.g. select disk 1.
The next step is to clean all volumes and partitions on the disk. Use clean command to do that.
The last step is to create a primary partition. You can do that using create partition primary command. That’s all. You should be able to format your flash disk now.
 So you can also repair your drives Formatted with FAT32,FAT16,EXT2,NTFS etc

DISKPART> list disk

  Disk ###  Status         Size     Free     Dyn  Gpt
