The techinaian said that 1571 have >bad machinism defective and head defective. It costs me $130. After two years of use one of my #1571's did the same thing. I recalled a FOG article about an Ossie that did the same thing, and the author's solution. I got out my "red" and "blue" stereo contact cleaner, removed the corrosion and cleaned the pins on the serial plugs to the #1571. Replugged everything, and my #1571 has been humming along happily ever since. It took five minutes, and cost nothing. Cleaning the serial contacts is now part of my annual maintenance schedule. [BTW, if you want #1571's and #1581's that run so quiet that you do not even know they are working, use a light silicon or teflon (from Radio Shack) based oil on the head tracks, as part of routine maintenance. It will make your drives as quiet as a RAM Disk, almost.] Howie Herman UUCP: {ihnp4!scgvaxd!cadovax rutgers!marque}!gryphon!pnet02!howie INET: howie@pnet02.cts.com

I found TriFlow to work better than the Silicon grease I had used previously. You have to be careful not to spray the stuff where you shouldn't. I will spray some on the shank of a screwdriver and then let the resulting drop fall onto the part being lubed. -- Jim Harvey | "Ask not for whom the bell Michigan Bell Telephone | tolls and you will only pay 29777 Telegraph | Station-to-Station rates."
