Sony SDT-5200's seem to work fine and SDT-9000's work for us on other machines with DPT controllers. Running async adds around 10% to the tape I/O times so that aspect's not earth shattering.... more concerning is that sommat is flaky and might bite under some other circumstances. Anything I can do to help track this down? -- Regards, Russell -------------------------------------------------------------------------- | Russell Brown | MAIL: russell@lls.com PHONE: 01780 471800 | | Lady Lodge Systems | WWW Work: http://www.kings.demon.co.uk/ | | Peterborough, England | WWW Play: http://www.kings.demon.co.uk/russell/ | -------------------------------------------------------------------------- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe aic7xxx" in the body of the message
