Overview of Format Disk Error

Today, when I plugged my Sandisk SD memory card into my PC, Windows warned me 'You need to format the disk in drive H: before you can use it.' Is there any way to fix this error without losing my data?

You need to format the disk in drive before you can use it

When you unplug an SD card, USB drive, external hard drive or any other removable storage without using the Safely Remove option, you run the risk of the disk partition becoming corrupted. Should this happen, then the device will be unreadable by Windows, prompting the appearance of the 'You need to format…' warning message. 

While this is the most common reason for causing a drive to become RAW and rendered unusable, there are some other instances that can create the problem. These include the following:

  • The storage device suffers from a sudden power outage
  • The storage device is infected by a virus
  • The file system of the disk is not Windows-compatible
  • There are bad sectors in the USB flash drive, SD card, memory card, or external hard drive

Fixes for the "You Need to Format the Disk in Drive" Error

When you see the warning "You need to format the disk in drive", it doesn't necessarily mean something is wrong with your external storage device. So, don't hurry to format the disk as the prompt says, as that's the last solution you want to try. Instead, here are a few methods you can use to fix the error.

Tip 1. Try Simple Solutions First

Before trying anything technical, it's a good idea to rule out any basic issues. With this mind, here are a few things to check.

Try a different computer: Connect your external storage device to another computer, either a Windows PC or Mac. If the device works properly on macOS but not Windows, it's highly likely that the file system of the device is not Windows-compatible.

Run antivirus software: It's possible that the "You need to format the disk in drive before you can use it" error is caused by a virus attack. Try running your antivirus software to see if that clears the problem.

If the methods above aren't successful, don't panic. There are several more options below you can try that will hopefully get your data back safely.

Tip 2. Check and Repair Your Device with CHKDSK Command

Many users have reported that this method has helped them solve the 'format' problem. It involves entering code, so if you're not confident with this kind of thing, you'll probably want to skip onto the next tip instead. Otherwise, here's what you need to do.

Step 1. Press the "Windows" key and type cmd.

Step 2. Right-click "Comand Prompt" and choose "Run as administrator".

Step 3. In the CMD window, type chkdsk G: /f and hit "Enter". (Replace "G" with the drive letter of your external storage device.)

Step 4. Then Windows will start checking and repairing disk errors and damaged files. Wait for the process to finish.

When it has finished, you can try again to read your USB, SD card, or external hard drive after restart your computer. 

If you see the error message 'the type of the file system is RAW, CHKDSK is not available for RAW drives', you'll need to perform a raw drive recovery to retrieve your data. We cover this method in the next tip.

Tip 3. Recover Files and Format the Disk

If all the above solutions fail to fix the problem, the next course of action is to recover files from your external hard drive, SD card, memory card, USB drive or other storage media first, then reformat the drive. 

This allows you to retrieve your data and get the storage device working again, without risking any data loss in the process. To recover your files safely, we recommend the reliable hard drive recovery software - EaseUS Data Recovery Wizard. 

These are the steps to take to recover your files:

Step 1. Scan the hard drive partition
