Well, I don't clean as often as it suggests (once a month or so instead of once a week), does diags I posted suggest this is a cause? As it is, I gave the head a good clean and this appears to have made things worse, so I guess you are on the right track. After cleaning the head I can't even get it to do a 'ftmt status' without it reporting an error (see attached density 4 report) so I guess something is going badly wrong with the unit itself (at least I know it isn't ftape). > If that fails, recheck the electrical connections ... they may be bad by > now. All that checked out ok. > Does the tape drive read written tapes OK? Given all of the above I'm a little loathe to place a "good" tape into the drive as a test. I don't want to be running without a backup and be using my last good backup(s) as test tapes. Or am I being a little too paranoid? Many thanks for your ideas and suggestions. -- Take a look in Hagbard's World: | w3ng - The WWW Norton Guide reader. http://www.acemake.com/hagbard/ | eg - Norton Guide reader for Linux. http://www.hagbard.demon.co.uk/ | weg - Norton Guide reader for Windows.
