Windows could not complete the format causes

There are several causes that your windows could not complete the format and here, I will list the possible causes and profess a solution after.

  • Defective sector available in storage devices: Storage devices have small sectors that are the smallest unit for storing data. Defective sectors mean that the sector is damaged and a reading and writing process can be done. Therefore, the availability of a bad sector may be one of the reasons why it does not allow windows to format the drive.
  • Virus attacks: This is one of the main reasons that can easily corrupt any data storage device. If your data storage devices are damaged or infected with viruses, then it will corrupt the data stored in it and you may not be able to perform any tasks, such as accessing the data, as well as formatting the storage device.
  • Damage to the data storage device:  another reason is the physical damage that makes the data stored on the storage device inaccessible. It is possible that the computer can not format the storage device if it can not use the device because it is physically damaged, such as the circuit board or the chip does not work, etc.
  • Storage devices are write-protected:  if your storage device is write-protected, you may receive the error message “The disk is write-protected. Remove the write protection or use another disk.”, While trying to transfer files from it. You should know that the format is a type of write operation and, therefore, you should remove the write protection before formatting the storage device.
