I transferred file f to an USB and when the transfer was complete, I ejected the drive but the system showed an error. When I reinserted the drive and did ls -l in it, it reads

-????????? ? ? ? ? ? fileName

against the file. File is not visible and I am also not able to over-write it. It can't be accessed thorugh the terminal also.

  • Were you writing to a USB disk drive, or a USB flash drive? If a flash drive, just reformat it and try again. Let us know. Cheers, Al – heynnema Sep 17 '16 at 19:14
  • I was writing to a usb flash drive. You are right that formatting will do but I am trying to understand what actually happened? – agyeya Sep 21 '16 at 5:25
  • You'll know what happened when you try to format it. If it fails, it's probably just gone bad. Cheers, Al – heynnema Sep 21 '16 at 15:35
