I was a long time Atari user. Was kind of obsessed. I got my Atari 400 in 1981 and loved it. While I've had an Atari emulator on every computer I've ever had (from Darek Mihocka's Xformer to Altirra), I recently got the urge for real hardware again. I bought my two original machines a 400, an 800XL, and a 1050. I went a step further and even bought the Atari 800 that I always dreamed of having back in the day! My 10 year old thinks they look "Powerful". I discovered I needed an XF551 because I wanted to look at some of the old programs I wrote again but they are save in the XF551 DS/DD format. I just got an one off of Ebay sold as "in box, untested, looks new". When it came I was pretty happy because the thing actually does look new, no marks at all and no dust, even in the creases. It even has that new smell to it! Unfortunately it doesn't work. When its turned on it makes a horrible head grinding noise and that's about it. I opened it up to see if there was anything obviously wrong but inside looks as new as the outside other than it missing that small metal shield that sits on top of the upper head. Is that enough to cause the drive to not work? I slid the head over and turned it on. The head moves back to the starting position then grinds. The metal shield is nowhere to be found. The SIO port solder joints look solid. I cleaned the heads with alcohol, even though they look immaculate. Does anyone have an ideas to what could make what looks like a new drive just not work?
Thanks for any help.
