Virus or Malware: Since flash drives are often connected to many computers, the chances of them getting affected by a virus is quite high. And when it is indeed affected by virus or malware, the best option you can do to wipe out all the viruses is by formatting the USB drive.
Checking and fixing bad sectors: Like we discussed before, having bad sectors on your USB flash drive can reduce its storage as well as life span.
When you format a USB flash drive without enabling quick format, the computer scans for bad sectors on the flash drive and fixes them. This is a great way to ensure your USB drive is working in its best shape.
File deletion: Formatting is also a mass delete option that will erase all the data present on the USB drive. If you have lots of redundant files on the USB drive, then all you have to do is format the drive and all the data will be wiped out.
File format change: There are a handful of file formats that are available for USB drives, but they are not compatible with every operating system out there.
For example, if you were to format the flash drive with NTFS file format, then you cannot write any data into the drive when it is plugged into a mac system.
Likewise, if you format the flash drive with the APFS file format used by macOS, it won’t be readable by Windows computers. The safe bet when it comes to compatibility between the two platforms, choose ExFAT.
