Why you need to format pen drive?

Nowadays, pen drives are more and more popular in our life due to their good properties and they are portable and tiny. If you buy a new pen drive without formatting, you must format it in advance so that you can use it normally. No matter what operating system you are using, it has a certain way to manage disks, and only the formatted disk structure can be recognized by the operating system. So, if you but a new pendrive without format or create a new partition, you must do a format for it.

Besides, some electronic devices just support only one file system. If the file system of your pendrive are not the supported file system of that device, the pendrive cannot be used normally. At this time, you must format it to the suitable file system.
