Repeated battery errors

My Disk System is constantly giving me battery error 02, even though I've put brand new batteries in it. I lack an AC adapter that works with the FDS. Any ideas what could be causing this?

(Before this happened, I was having several other problems as well, but can't really do anything about those until I solve this one.)

The power board could not be connected properly, or could be bad, or the drive may have a mechanical fault (yet generates an Err.02). I also have power supply units for the FDS (new old stock, USA voltage)  :bomb:

I had this error (02) constantly before I changed the belt for an original new one from tototek. Now I'm getting error 22 :D But that's not the point ;D

Err.22 is from problems with the spindle assembly and index alignment (and general mechanism calibration).  :bomb:

BadWolf42

Thanks for that. Turns out the little cable that connects the drive to the power board wasn't fully seated.
So even though I'm not getting battery errors anymore, I still got error 22s, accompanied by a loud squeaky noise.  Tweaking the spindle hasn't fixed it, and now it doesn't give me anything at all. It just says Now Loading... and the drive itself gives up moving after a while. Suggestions?

You may want to check the height of the spindle--if it's too high the disk media won't contact the magnetic read head. If that seems okay, check the pressure arm to see if the pressure pad is still attached.

BadWolf42

Yeah, the pressure pad is still there. I'm experienced with dealing with those because that's one of the problems my first Disk System had.

How do I know what the height of the spindle is supposed to be?

My last major piece of free advice on this subject for a while...

This problem can be caused by one (or more) of the following:

  • Improper spindle /index  alignment ; this is then combined with drive motor settings.
  • One or more damaged trigger switch(es) on the analogue board.
  • An improperly seated analogue board.
  • An impediment in the head-sled assembly.
  • A dirty read head.
  • A user-adjusted read-head (de-calibrated: The read-head distance is factory-calibrated and frozen in wax, and changing this setting will almost always damage performance.
  • A weak head-return-spring.
  • Weak or missing card-carrier spring(s).
  • A weak or damaged media-pressure-arm tension spring
  • Card-carrier: Impediments on smooth / total closure.
  • Motor failure: Motor is not maintaining a consistent speed of rotation on the pulley assembly.
  • Bent / warped frame assembly; or card-carrier sub-frame.

    I have personal flowcharts of these sorts of problems, as I've pretty much seen the worst of the worst and had to rectify it. I can't say that there are not problems that I have yet to see, as there are always weird mutilations that people cause to their hardware, but I've repaired almost every imaginable fault that an FDS can develop (or have done to it by human mangling).

    With what disk are you attempting to calibrate your drives?

    @JPX: Now you see what I mean about the 3-D calibration... :bomb:

BadWolf42

I have two disks, one Zelda no Densetsu and the other Metroid. However, since I have never had a functional FDS, I'm not sure if the disks themselves are good.

For the record, I did try to calibrate the read-head myself, but I have another drive with an unadjusted one. That drive is missing the pressure pad, and may have other potential problems. Would you recommend  trying to Frankenstein the two together to try and get a working drive?
