Erase USB or Clean USB or Format USB?

We’ve seen these terms floating around in forums and How To’s for years when someone is explaining what to do with USB flash drives. I think most people glaze over the definitions of Clean, Erase and Format simply because they believe the terms are interchangeable, or they aren’t planning on doing the task mentioned in the post.

I hope the following information will clear up some terms and definitions so we can all better understand what people are talking about when passing along information about flash drives and the Clean, Erase and Format function.

All of these functions can be performed in your Windows 10 computer, or higher. I will start with the least complicated definition and task, and move along from there.

Format

This function is what 98% of Windows computer operators will use. This is the graphical interface inside Windows when you right click a drive letter and ask the operating system to format the drive. What is this function really doing?

Format is the least complicated of the tasks, and this function is removing the File Allocation Table of the USB and creating a new one. Said a simpler way… this function takes away the list of files sitting on the drive so it then appears blank with no data.

It’s important to note, the files are still on the drive, just not listed in an easy, organized manor which you can see through windows explorer (clicking on the drive letter to see the list of files).

Using the most basic file recovery software tools, like the one we wrote about several months back, you can recover all the files sitting on the drive.

Maybe a picture will help. Looking at the image below you can see the “data” is light grey. Meaning the data is still there, just not easily accessible. This data is what recovery software will look for, find, and list back on your drive. Also notice the boot code of the USB (if you want to load an operating system on your USB stick) isn’t touched either.

You might have questions if a USB flash drive should be formatted as FAT, FAT32, exFAT or NTFS and we did a great post about that a bit earlier as well.

Clean

The Clean function is a bit more in-depth than the format function. This function applies directly to the Master Boot Record (MBR) or boot code mentioned just above.

The Clean function will clear out boot code and will remove any partition on the flash drive. The partition of a flash drive is the information which tells a host computer how big the drive is, and if the partition should be bootable in the event you are trying to start the computer from a flash drive.

The Clean function is not accessible through the GUI of Windows, for example you cannot right click on a drive letter and find the Clean function. The Clean function is only accessible through the Windows utility called DiskPart.
