What Does Formatting Do to a USB
Formatting prepares the USB drive for use by recreating the file system. If you want to erase all data on your flash drive, formatting is one of the solutions you can opt for. Its benefits include:
- It’s quick.
- All files can be deleted with one click.
- It doesn’t require much tinkering.
- Quick formatting: If you choose this formatting type, all files will be instantly removed from your USB drive, but the drive won’t be scanned for bad sectors.
- Full formatting: This formatting type works exactly like Quick formatting, but it also scans the formatted USB drive for bad sectors, which is a time-consuming process.
- Secure formatting: Various third-party tools let you securely format your USB drive by overwriting its content at least one time with new data, making data recovery impossible.
Do You Need Formatting to Access Your Data?
If you’re worried that you need formatting to access your data on a USB drive that says it needs to be formatted or can’t be accessed by Windows File Explorer, you can relax as there are solutions. In cases like this, it’s usually the fault of the USB flash drive as it’s gotten corrupted or damaged. The message usually says: ‘You need to format the disk in drive X: before you can use it’, as shown below.
Typically, scanning the problematic USB drive with CHKDSK is all it takes to make the error message go away and your data to become accessible again. Here’s what you need to do:
- Open Command Prompt as administrator.
- Enter the following command: chkdsk X: /r.
How to Format a USB Without Losing Data
During formatting, all data on the formatted device is always deleted so how can you format a USB without losing data? Well, you have to create a backup first. Then, you can format the device and transfer your data back to it from the backup.
The extra step is well worth it if you suspect that your USB drive is corrupted and previous attempts to fix the corruption using tools like CHKDSK have failed to yield good results.
Back Up Your USB Drive
Before you format your USB drive, you need to back up all important files to a different storage device, such as your system drive. You can, of course, simply move the files using File Explorer, but there are even better solutions available.
You can then mount the backup as a virtual drive and easily transfer any files from it back to the formatted USB drive. Here’s what you need to do to create it:
- Download and install Disk Drill.
- Select the Drive Backup feature from the left pane.
- Choose your USB drive and click the Byte-to-byte Backup button.
- Pick a suitable location for the backup.
Format Your Drive
There are several ways you can format your drive, including:
- Using File Explorer.
- Using Disk Management tool.
- Using Command Prompt.
Using File Explorer
- Open This PC, which will allow you to see all the drives easily.
- Right-click your drive from the File Explorer.
- Click the ‘Format’ option.
- Set the options the way you want them and click ‘Start’.
Using Disk Management Tool
- Right-click on the Windows icon in the lower-right corner of the screen.
- Click on the Disk Management tool.
- Find your USB flash drive on the list of Volumes and right-click on it.
- Select the format option.
Once you complete these steps, you will have a USB flash drive that’s empty, as if you took it out of the package.
Using Command Prompt
- Type’ Command Prompt’ in the Windows search bar and open the program.
- Type ‘diskpart’ and hit Enter.
- Once the Diskpart window is open, type ‘list disk’ and press Enter.
- Type ‘select disk (the number of your disk)’.
- Type ‘clean’.
Once you follow these steps, your drive will be formatted, and all you have to do then is to make it accessible again by:
- Typing ‘create partition primary’.
- Typing ‘format fs=ntfs’ and hitting Enter.
Restore from a Backup
Assuming you’ve used Disk Drill to create a byte-to-byte backup of your USB drive before formatting, you can now use the same application to restore your data:
- Launch Disk Drill.
- Click the three dots in the upper-right corner.
- Select the Attach disk image option.
- Choose the byte-to-byte backup of your USB drive to mount it.
- Select Data Recovery from the left pane and select the mounted image.
- Click Search for lost data to scan the image.
- Click Review found items to see the content of the image.
- Select all files you want to restore.
- Click Recover and choose your USB flash drive as the destination.
No Backup? Scan Your USB Drive Using Data Recovery Software
If you’ve formatted your USB drive but forgot to back it up first (or have lost your backup somewhere in the process), then not all hope is lost just yet. You can still recover your data using data recovery software like Disk Drill, which is known for being reliable, affordable, and powerful.
To scan your USB drive and get back your lost items with Disk Drill, all you have to do is:
- Download Disk Drill from the application’s official webpage.
- Install Disk Drill and launch it.
- Click on the ‘Search for lost data’ button.
- Browse the list of scanned files and select the ones you want to recover (if you’re able to preview the file, you will likely be able to recover it too; the program will also display the chances you have to recover the lost data. High recovery chances are marked green, average ones are marked yellow, and the low ones are in orange).
- Click on the ‘Recover’ button and select a destination where you want Disk Drill to save your restored files.
Formatting a USB flash drive without deleting the data stored on it is a bit of an oxymoron since the purpose of formatting is to delete all data in one go. That said, the deleted data do actually physically remain on the formatted drive until they become overwritten by new files, and it’s possible to recover them using specialized software like Disk Drill.
