Formatting a hard drive or SSD in Windows 11 erases any existing data on a drive and prepares the disk for use. Luckily, formatting is very easy to do directly from File Explorer. Here’s how.
Format a Drive in File Explorer
First, open File Explorer. You can usually do this by clicking the folder icon in your taskbar. Or you can right-click the Start button and select “File Explorer.”
In any File Explorer window, browse to “This PC.” In the list of “Devices and Drives,” right-click the drive you’d appreciate to format and select “Format” in the menu that appears.
A “Format” window will open. It presents options about how you want to format your drive. We’ll go over each item one-by-one so you can ascertain
- Capacity: This will be the data capacity of your hard drive or SSD once it is formatted. Formatting takes up some of the raw disk space because of how file systems work.
- File System: A file system is a data structure that tells an operating system how to save and load files to or from a disk. Depending on the drive’s size, your options will be FAT, FAT32, NTFS, or exFAT. In general, you’ll want to select NTFS if the drive will only be used with Windows. If you want the drive to be readable and writable on a Mac as well, pick exFAT.
- Allocation Unit Size: This is the basic block size used by the file system when you format your drive. Generally, you never need to change this setting, so use the default allocation unit size that appears (usually 4096 bytes for NTFS) when you select the file system you want.
- Volume Label: This is the drive name that will appear when you see your formatted drive in File Explorer.
- Format Options (Quick Format): If the drive is in good working order, you can select “Quick Format,” which performs a high-level format and finishes quickly. The data is still on the drive but all references to it are lost, so it will be overwritten as you use the newly formatted drive. Unchecking “Quick Format” makes Windows check the disk sector-by-sector with a low-level format that takes much longer, but it will also wipe all traces of any old data completely.
Once you have every option how you want it, click “Start” to begin the formatting process.
After clicking “Start,” Windows will pop-up a warning message telling you that “Formatting will erase ALL data on this disk.” Click “OK” if you’re ready to erase the drive and format it.
When you format your hard drive or SSD, you will lose all data on the drive. Be absolutely certain you have backups of any data on the drive before going any encourage!
While Windows formats the disk, you’ll see a green process indicator proceed from left to right. When it’s completely full, the format will be complete, and you’ll see an alert pop-up. Click “OK.”
If you the format fails, there are easy ways to fix the “Windows Was Unable to Complete The Format” error.
After that, close the format window and you’re ready to go. Your newly formatted drive will show up in File Explorer, and it’s ready to store data. If you need to format another drive—or wipe data from it—just right-click the drive in File Explorer and click “Format.”
If you only need to format a drive, File Explorer will work just fine. However, the Disk Management Utility has more advanced functions appreciate partition management that is useful in many situations. Depending on why you’re formatting your drive, you may want to use that instead.
