|Peter Wemm stands accused of saying: |> I've been fighting with a "Model: CDR-55JD" NEC drive for the last few |> days. This drive and I have reached an understanding.. We both HATE |> each other. | |I bought an NEC CD drive some time ago; it was so much of a crock that I was |forced to return it & replace it with a Matsushita unit. NEC admitted that |(despite their marketing claiming it was a SCSI-2 unit) it was only a |"pseudo-scsi" (their words) drive that would only work properly with their |drivers. I haven't had any problems with my NEC CDROM drive since I have had it. It is a CDR-501, a 4x SCSI internal. It has worked well with FreeBSD 1.1.5.1 to 2.1. I'm currently running it off of a Adaptec 2940 and use to use it on an Adaptec 1542cf. |I couldn't get it work under 2.0R, or on a Mac, or my old Atari TT, or |even under DOS (I bought the drive bare). I have had no problems with it using it with DOS, Windows 3.1, or Windows 95. |I have no faith whatsoever in NEC's ability to produce SCSI CD units, so |reading about your problems doesn't surprise much 8) | |> I *hate* that drive... If the other NEC drives are like it too, I'll |> be very reluctant to touch them ever again. | |This is my experience. | |> BTW: I, too, would dearly love to know what the other jumpers are for. |> I suspect #5 or #6 is termination enable, but I'm not sure. | |My guess is termination enable terminator power to the bus; you can check |this easily enough with a beep-meter. If I recall right one of these was for termination, but I don't recall which and what the other was for. I still have the manual for the CDR-501, but I'm not at the same place it is. So if you would like to know what they are for drop me some email and I'll get you that information. |> -Peter | |-- |]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ |]] Genesis Software genesis@atrad.adelaide.edu.au [[ |]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ |]] realtime instrument control (ph/fax) +61-8-267-3039 [[ |]] "Who does BSD?"
