How To Repair Corrupt USB Flash Drive

Is your USB drive broken? The USB flash drive repair tool can help you to recover your damaged or corrupt USB pen drive. The USB flash drive may damage while you are trying to install a new operating system. While creating many partitions or due to some virus that corrupts the entire USB drive. 
You can use the same tool for SD Cards and other portable storage devices. 
I was trying out the Google Chromium OS. After the test, I tried to format my USB flash drive. But the USB drive was completely destroyed and had only 1 GB usable space. 
The other 3 GB space was not accessible. When opened the Windows Disk management tool, there were 8 partitions. Out of 8, only one partition was usable by Windows. All other partitions were of no use.
How To Repair Corrupt USB Flash Drive
Most of the time, the default Windows drive formatting feature may not help you. Here is the comprehensive list of features you may try to recover the problematic USB drive and also recover files if possible.

There are multiple ways to fix the corrupt USB drive. The Windows have built-in disk management utilities. You can either use them or specialized third-party tools can also help you to recover the damaged USB disk.

 This tutorial includes following 4 ways to repair USB drive
1Repair using CMD
2Repair using Disk Part
3Repair using Windows Disk Management
4Repair using Bootice


Format USB Drive using Windows Command Line
> Open Run dialog. (Windows key + R )
> Change the working drive to your USB drive and use the command <format F:> where F: is using USB drive letter.
>Press <Y> to close all other programs from using the drive and this will format the USB drive forcefully.

Most of the time this basic thing works and solves problems. If this does not work, use the next step.

Use Disk Part

Fix damaged USB Drive using Diskpart
> Open Run dialogue.
> Run <diskpart>
> <list disk>
> This will display all the drives. Identify the correct drive letter.
> <select disk 2>
> <clean>

This will completely and forcefully format the drive. If you still not lucky, you may try the next utility.

Use Windows Disk Management

Fix Curropt USB drive Using Windows Disk Management 
 Right-click on the Start button and select 'Disk Management'.
 Select your USB drive from the list.
If the drive is missing the drive letter, you can allocate a new drive letter or format the drive or change the file system type.

If nothing of above works, try the specialized tool. This will surely recover everything.

Use Bootice

Many attempts to recover deleted portions failed. Using may specialize applications but no use and the one that was perfect was a very tiny but a powerful tool 'BOOTICE'.
