Recently , you purchased a USB flash drive that you plan to use to store work-related files. When you attempt to store a file on the USB flash drive, the computer displays an error message indicating that the file will not fit. How could a brand new flash drive not have enough room to store the first file you attempted to store on it?


You failed to mention what operating systems are involved. What does the work computer use as an operating system. The file system format of the USB may be say as an example ntfs windows while as a hypothetical the work computer could be apple o/s using a different file system or even maybe a unix system. You may need to reformat the usb stick to be the format file system used by the work computer. Also there could be a policy in place to prevent usb sticks working on work computers to protect intellectual property or to protect against virus transferance.

  4. Highlight StorageDevicePolicies, and then create a New DWORD (32-bit) Value named as WriteProtect.
  5. Double click on WriteProtect, and set its value data to 1. write-protect-usb.jpg

The media is write-protected.
Remove the write protection or use another disk.
