My USB device is not working properly. It causes some error while formatting, seems like it had bad sectors? How can I low-level-format my USB?

Will this help removing bad sectors from it? Also, how can I define sector size during formatting?

What is low level format?



Low Level Format (LLF) is the process of delineation of the tracks and sectors on the hard disk, and writing the control structures that characterize the tracks and sectors. This is called a "true" formatting; because it really can make the physical change and locate where the data is stored in the disk. Please note, when a company makes a Hard Disk, then it would be the first time they performed it from factory.

  • Yes, you can do LLF into your Flash Drive also. Please download HDD Low Level Format Tool from the link
  • You cannot do it during LLF. You can do it after LLF, when you will start partition on your HDD. At that time, you can define your own.
