As I mentioned above, I have lost my pendrive. Its not useful for me until I recover the memory. I am using here Windows 10 OS to recover my lost space.

Windows OS is providing feature to manage your disk partitions using diskpart command.

Open command line or run command and type diskpart.

1. Check the list of disks in your computer.

2. Select your disk that you want to recover. You need to be very careful here , because if you choose the wrong disk you might loose some other data. So, here I am choosing disk 1. Because, its a common sense  my USB Drive capacity is 16 GB.

       select disk 1

3. Now , do clean for your chosen disk.


4. Now, you have already got successfully cleaning the disk message. Now you need to create a partition for your disk . This is the primary partition, though you are creating only one drive.
