Is the command format d: /fs:exfat /q valid? If so, what is its effect, and what precaution might you need to take before running it?
Click to show answer
Yes, it is valid. It formats drive D with the exFAT file system by using a quick format (does not scan for bad sectors). This will delete the file table on the drive so existing data files can be overwritten—the formatted drive will appear to be empty in Explorer. If there are existing files that need to be preserved, they should be backed up before running the format command.
