Errors while copying files to a removable disk

Since a few days so far been giving me this error when trying to copy files to a removable disk, each time with a different file, and I do not know if it will be problem of the disc. What do you think?

you can get to try some other equal or similar device?

or try same device on another PC?

I will try to load the same files,at another PC

Thanks for the suggestion!
