USB Flash Drive

a repair is required. Microsoft Windows provides a disk repair utility
called "Chkdsk" which checks for errors and will repair any errors it
finds.

HOW TO RETRIEVE DATA
If your flash drive has been formatted unintentionally and you want to retrieve the data you can use some retrieving tools found on internet. There are a lot of retrieving tools so don't have to worry about it..I tried many times retrieving datas from formatted drives. For me I'm using "File Scavenger."
1. Click "Start" button, then click on "Computer." A
new window will open in which you can establish the drive letter of the
defective flash drive. Drive letter "C" is usually the system which Windows is installed. Letter "D" is maybe the
CD/DVD drive. For the purpose of this article, lets's assume that letter
"E" is the flash drive.
2. Click on Windows "Start" button and click run. You ca also do this by pressing "windows + R" on your keyboard, the type cmd and hit enter.
NOTE:
If drive letter "e" is not the correct letter for the flash drive,
change the letter in the command, in Step 3, to the correct drive
letter.
