Reasons why you would want to reformat a USB or SD card

You may want to reformat a USB drive for various reasons and here we begin this article by explaining them.

  • Usually, when you buy a USB drive, it is formatted using the FAT32 file system by default. This is perfect for use with Windows PC’s because Windows PC’s are designed to work well with FAT32. However, with Mac’s things are a little different. Although Mac systems are designed to read and write to USB’s with FAT32, it does not provide the best experience and you may run into problems at times. In order to overcome this issue, you can reformat the USB using a file system like HFS+ that is Mac friendly.
  • If your USB or SD card has been hit by a virus, things may not work as expected even if the virus has been removed. In that case, reformatting is the best option.
  • If your USB drive or SD card is corrupt and other troubleshooting steps like CHKDSK don’t work, then re-formatting is pretty much the only choice you have. Although this step will delete all data on the USB, it is a good option to repair the USB drive provided you have a backup.

Now that we have understood the reasons for re-formatting a USB, let us proceed to understand how to actually reformat the USB drive or SD card in Mac.
