Many thanks yet again to the very kind _Bernhard Wulf_, who took time out of his busy day to save my OD3210 by sending me a special procedures document which details resetting the NOVRAM and conducting a few calibration tests after servicing. Anyone with any Overland tape drive, feel free to email me directly and I'll send you the .pdf file... but send your thanks to Bernhard. So, to recap, replacing the battery on my 3210's PWB caused the battery backed-up non-volatile memories to get scrambled, resulting in an 4x/second flashing ALERT upon after-service POST. Using the special procedures (not documented in the user manual where they should have been), I was able to reinitialize the NVRAM contents and recalibrate the drive. I know for a fact that this same problem has stymied several people before me, some of whom probably disposed of their perfectly good drives as a result. Thanks also go out to Chuck Guzis and Tony Duell for their clues and suggestions. - John S.
