However, sometimes I force uucico to run from the keyboard at other times during the day, I get no unix.log entries. I don't know why they both happened on Tuesday, as my uucico cron runs daily. Can anyone tell me what causes these messages to happen? They don't appear to be "hard" errors (non-recoverable). Should I add this block to my bad block table? How do I go about doing that? Thanks in advance. -Todd-
