You need to format the disk in drive before you can use it
“I have a 16GB USB flash drive that I bought 2 years ago. I often plug it to my laptop and computer in computer, so that I can read or prepare working files at home. Just now I plugged it to my laptop as usual and open “This PC” to open the USB flash drive, but I couldn’t open and received error “You need to format the disk in drive G: before you can use it. Do you want to format it?” I don’t want to format it, because I don’t want to lose all my files and folders. I clicked “Cancel” button. What else can I do to remove this error and regain my data?”
This is a common error we see if the partition is intact but the boot sector is missing or corrupt. It happens quite often on external drives due to not safely removing the drive before disconnecting it. File system of the partition gets damaged due to improper removing the disk, and formatting can fix system error. This error also happens to almost all external devices such as external hard drive, USB flash drive, SSD, SD card, pen drive, etc. If the drive contains files that are important to you, you shouldn’t try any solutions to fix or format it. The first steps should be recovering data from the inaccessible disk.
Fix “You need to format the disk in drive before you can use it” error
Solution 1: Run chkdsk to repair disk
- Open Command Prompt. Windows XP/Vista/7: Click “Start” button to find out All Programs and then click Accessories. Right-click Command Prompt and select “Run as Administrator”. Windows 10/8.1: Right-click the Windows button and choose Command Prompt (Admin).
- Type command chkdsk G: /r and press Enter button. G here is the drive letter of the USB drive in question, thus it might be other letter on your computer. In that case, you need to change G with your own.
- Select Yes if you are asked to recover files. If the command above doesn’t work, try chkdsk G: /f
Solution 2: Format the disk
If chkdsk can’t complete and reports “the type of the file system is RAW, CHKDSK is not available for RAW drives“, file system on this disk can’t be repaired. Thus we should format the disk in computer.
