How to Clean USB Flash Drive
You must have used a USB flash drive in your daily work and study, but have you cleaned it? How to clean USB flash drive? Here we list three methods to help you successfully clean a USB flash drive from a Windows computer. Keep reading and choose one way according to your needs.
Way 1: Clean USB Flash Drive in File Explorer
To clean a USB flash drive, you can use the Windows built-in File Explorer’ Format option. Formatting is the fastest and easiest way to clear data from a USB flash drive.
When you format a USB drive, the data is in the sector, it’s just inaccessible to the operating system. Before a particular sector is overwritten, you still have a chance to recover it. But if you don’t have any sensitive data on your USB drive, this method might be suitable for you.
How to clean flash drive in File Explorer? You can follow the steps below:
Step 1: Connect the USB flash drive to your computer.
Step 2: Press the Win + E key to open File Explorer and make sure the USB flash drive can be detected in File Explorer. Then right-click on the drive and choose the Format option.
Step 3: In the pop-up box, select a File system you want, and then uncheck the Quick Format box. Because Quick Format only deletes the files on the USB flash drive but not fully erase them, which makes the data easy to recover. Read this article to know the difference between Quick Format and Full Format.
Step 4: Click on Start to execute the formatting process and wait for it to complete.
Way 2: Clean USB Flash Drive with DiskPart
DiskPart is a command-line disk partitioning utility that gives you options to format or clean a drive. Here, I will describe how to clean flash drive using CMD as it is a safer way to wipe data.
But be aware that if you use the “Clean” command, it will not completely wipe the USB drive and the data will still be recoverable. To safely remove sensitive information, use the Clean All command. It will take longer time than the “Clean” command but is safer. Read this article to know the difference between Clean vs Clean All in DiskPart.
How to clean flash drive using CMD? You can follow the steps below:
Step 1: Connect the USB flash drive to your computer.
Step 2: Press the Win + S key to open the Search bar. Then type cmd to locate Command Prompt and right-click on it to choose Run as administrator.
Step 3: In the elevated window, type diskpart and press Enter.
Step 4: Then type the commands below in order and press Enter after each.
- list disk
- select disk # (# presents the number of the target drive)
- clean all
Step 5: Wait for the finish of the cleaning process. Then exit the command window until you see Disk succeeded in cleaning the disk.
After the process is completed, all the partitions on the USB flash drive will be wiped out. If you want to keep it for reuse, you can initialize the disk then.
Still, using Diskpart to clean a USB drive has certain risks, especially for people who are not good at computers. It is inconvenient to distinguish which disk is a USB flash drive. If you make a typo in the command window, it may cause some errors. So, here we recommend a third-party free partitioning program – MiniTool Partition Wizard. It is much easier to operate even for novices.
