When I plug in USB, the drive’s disk needs to be formatted before use. What should I do…?
The only way to repair or fix the problem, you only can fix it by formatting the USB and best to backup all your data first, give it a try.
This “the drive’s disk needs to be formatted before use” error message that appears when the file system structure is damaged. If there is no data on the USB, you can just format it.
You can restart PC or connect USB to another PC. You can also check for problems on the external hard drive using CHKDSK or Disk Utility.
But if there are important files, you’d better recover them before you format the USB.
Thank you so much, I will have a try.
It’s very nice of you, thank you!
