Tech Question - Abnormal behavior from my Sharp MD-MT 200

I have a Sharp MT-200 mini-disc recorder. I got it about 3 years ago, have used it only occasionally to make concert or field recordings and it’s given me almost no problems, until recently.

A few weeks ago I taped a concert from the sound board of a local club using a Marantz PMD660 compact flash recorder (the Itals, if you must know). I daisy-chained my MD-MT 200 from the Marantz’s line output to the line input of my MD recorder in order to have a backup copy of the show in case the Marantz failed (I know, I should have used a separate output off the board, except that there wasn’t one to use that evening). I was using Memorex 80-minute blank MD’s, which have never given me trouble before (SONY’s on the other hand are a nightmare. More on that some other time.)

Anyhow, about 4 or 5 times that night (and with 2 different blank MD's) my MD-MT 200 would flash the message “DEFECT” on its display, and then re-set its time counter and put a track marker where the alleged defect occurred. When played back, each “defect” point contains a brief drop-out in the audio.

The only other time I have encountered this kind of behavior in my MD recorder is when someone else once tried to daisy-chain through my machine’s earphone jack into another MD recorder before I asked him to disconnect, and threw in a fresh blank disc. (I think he might have been using his MD unit’s MIC input - some tapers really need to get a clue).

What I need to know is, was this malfunction the result of incompatibilities between my MD-MT 200 and the PMD-660, or was it the fault of the MD recorder by itself? Did the PMD-660 inject signals or DC potentials into my MD recorder which made it behave abnormally? Did I get stuck with a bad batch of blank mini-discs? Or is it time for me to consign my MD-MT 200 to the county landfill?
