• To format a hard drive or SSD in Windows 11, open File Explorer, browse to "This PC," right-click the drive, and select "Format" to start the process.
  • When formatting, consider the capacity, file system, allocation unit size, and volume label. Select NTFS if using the drive only with Windows and exFAT if also using it with Mac.
  • Before formatting, make sure to back up all data on the drive as formatting a drive completely erases it.
