You can try some data recovery software. You can see
How to recover deleted files
It tells the steps how to perform data recovery.


If above does not work, you may have to format the USB Flash Drive(use quick format), and then use data recovery software to scan again USB Flash Drive and recover your files. You can refer to this tutorial
Recover deleted files after format

It should be the file system problem. Usually a usb drive should be formatted to FAT initially instead of NTFS. Recommend you try the USB on another computer and see if the problem still occurs. If yes, then try format it from Disk Management of your computer. If you can't format, use TestDisk (also a command line tool) to fix the file system error. You can also see from this blog post to learn more about the possible reasons or solution. Regards

Will not format - unknown capacity -

it's works on unknown capacity format problem


Requirements: A "corrupt" USB thumb/flash drive, and windows vista/7.


First of all, RESTART YOUR PC...(this is the only way it worked for me...hopefully it works the same for you)


1. Plug-in your USB flash drive to USB port.


2. Open Command Prompt with admin rights. Use any of the below methods to open Command Prompt.


*Type cmd in Start menu*


3. You need to know about the USB drive a little bit. Type in the following commands in the command prompt:


>>> First type DISKPART and hit enter to see the below message. (this opens the disk-partition manager)


>>> Next type LIST DISK command and note down YOUR FLASH DRIVE'S Disk number (eg: Disk 1). BE CAREFUL NOT TO CHOOSE YOUR PRIMARY HARD-DRIVE.


4. Next type all the below commands one by one. Here I assume that your disk drive no is "Disk 1".If you have Disk 2 as your USB flash drive then use Disk 2.Refer the above step to confirm it.
So below are the commands you need to type and execute one by one:


SELECT DISK 1


CLEAN


CREATE PARTITION PRIMARY


SELECT PARTITION 1


ASSIGN


FORMAT FS=NTFS
(Format process may take few minutes)


EXIT


If you did everything exactly, then your USB drive should be goos as new.

This will walk through the steps to create a bootable USB flash drive for the purpose of installing a Vista or Windows 7 OS. These instructions assume that you have a computer with Windows Vista installed on it.
Required:
· USB Flash Drive (4GB+)
· Microsoft OS Disk (Vista / Windows 7)
· A computer running Vista / Windows 7
Step 1: Format the Drive
The steps here are to use the command line to format the disk properly using the diskpart utility. [Be warned: this will erase everything on your drive. Be careful.]
Plug in your USB Flash Drive
Open a command prompt as administrator (Right click on Start > All Programs > Accessories > Command Prompt and select “Run as administrator”
Find the drive number of your USB Drive by typing the following into the Command Prompt window:
diskpart
list disk
The number of your USB drive will listed. You’ll need this for the next step. I’ll assume that the USB flash drive is disk 1.

Format the drive by typing the next instructions into the same window. Replace the number “1” with the number of your disk below.
select disk 1
clean
create partition primary
select partition 1
active
format fs=NTFS
assign
exit
When that is done you’ll have a formatted USB flash drive ready to be made bootable.

Step 2: Make the Drive Bootable
Next we’ll use the bootsect utility that comes on the Vista or Windows 7 disk to make the flash drive bootable. In the same command window that you were using in Step 1:
Insert your Windows Vista / 7 DVD into your drive.
Change directory to the DVD’s boot directory where bootsect lives:
d:
cd d:\boot

Use bootsect to set the USB as a bootable NTFS drive prepared for a Vista/7 image. I’m assuming that your USB flash drive has been labeled disk G:\ by the computer:
bootsect /nt60 g:

You can now close the command prompt window, we’re done here.
Step 3: Copy the installation DVD to the USB drive
The easiest way is to use Windows explorer to copy all of the files on your DVD on to the formatted flash drive. After you’ve copied all of the files the disk you are ready to go.
Step 4: Set your BIOS to boot from USB
This is where you’re on your own since every computer is different. Most BIOS’s allow you to hit a key at boot and select a boot option.
I used these instructions to get my new Dell Mini 9 laptop loaded with Windows 7 (the PDC bits). HTH.
