Write error on local filefilename
During the transfer of a file from a remote computer to your computer, the Tftp utility encountered an unrecoverable write error on your disk.
Retry the file transfer. If you still get this message, either run Chkdsk with the /r switch on your disk, or use a different disk as the destination of the file transfer. Then retry the Tftp command. You may need to contact your system administrator to diagnose your disk problems.
