There are many businesses that uses cheap flash drives as a marketing medium – they are used to store marketing material for customers to keep and as "premium" items as a way to reward loyal customers. It is a shame to toss them out, even if they have a small storage capacity. You can easily format USB flash drive and reuse them.

Do take note that reformatting your flash drive is the last resort for any situation. This is because it is not reversible and once the flash drive is reformatted, all data will be wipe off from storage. Therefore, make sure you have a back-up data if you decide to start this process.

Part 1: Reasons Why You Fomat USB

There is quite an extensive list of reasons why a USB format may be required. Before getting into them, let’s have a look at what formatting really is!

Definition Of Formatting A USB Drive

We hear a lot about formatting and why it's important not just to keep your data safe, but also for maintaining good health of the USB flash drive.

Formatting is the process where the data on the USB drive is completely erased and a new file format system is written on the device. The user can choose the file format system to be used prior to formatting. The most common file system used by Windows computers is NTFS. You can also use FAT32 or ExFAT if you want the USB drive to work on Mac systems too.

Another option you might have seen in the format window is the option to do a quick format. The difference between normal formatting and quick formatting is that normal formatting automatically checks for bad sectors. In quick format, no such scan is performed. Doing a scan on bad sectors is good for prolonging the life of a USB drive.

Why Format A USB Flash Drive or A Pen Drive?

Why do people format when they can just delete all the files and call it a day? The answer can be just summed up in one sentence. There are multiple reasons why you would want to choose format over just deleting the files from a USB drive. Let us review some of them!

  • Virus or Malware: Since flash drives are often connected to many computers, the chances of it getting affected with 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 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.
  • Selling or lending flash drive: When you are selling or lending your flash drive to another person, it is critical that they cant recover any files from your flash drive. Formatting your flash drive will help you delete all files within the flash drive. Changing the file system while formatting is also a great way to ensure that no data can be recovered.
