Recovering unallocated space of a USB flash drive.

Present by:- RAJ UPADHYAY

?? Question ??

Today when I made Linux (Ubuntu) bootable pen drive

and install Linux (successfully) in my system. When I attached pen drive then i found there where only 3MB space. I was amazed 8GB pen drive show me 4MB

space only!!!!!!!!

How to see UNALLOCATED space!!!!!!

• Go to start • Then type :- This pc• Open This pc.• Now follow the following

steps.

(for WINDOW

S 10)

For windows 7 or other windows system open My Computer

Step 1:- OPEN THIS PC

Step 2:- Right click on This pc & select Manage

In other windows system Right click on My Computer & select Manage. (other steps are same)

Step 3:- You will see new window as given below

Step 4:- Select Disk Management & wait for some time & you will see output as given below

Output will be deferred as system changes.

Let’s remove unallocated space. First of all run Windows command line and type diskpart in the command prompt. 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 2 in my case. Next you should chose the disk to work with. Type select disk <disk number> command, e.g. select disk 2. 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.

Step 1 :-

Windows will ask you for Administrator

permissions to run the tool

You will see new window like this

Now type command:- list disk

You will see list of disk. Now select the disk (according to your pen-drive) here, which has FREE space 3059MB. (In your case it may also different).

Now type command:- select disk 2 (number can be changed in your case)

After typing the command. You will see message “ Disk 2 is now selected disk”.

Now type command:- clean

After typing the command. You will see message “ DiskPart succeeded in cleaning the disk”.

Now type command:- create partition primary

After typing the command. You will see message “DiskPart succeeded in creating the specified partition”.

Now go to This pc & check the space of pen

drive .

In other system (other then Windows 10 ) go to My computer and check the size of pen-drive.

Let’s revise all this in one picture.

Thank you
