It prevents my good drive from reading when booting up. If I unplug the bad drive then the good drive boots fine. So from your comment it sounds like the 2003, or the input to the 2003, is the likely culprit. I'll look at that first. Thanks!
Actualy, check the '125 first. A shorted output there will kill the read channel for all drives, and that's a likely failure mode under the off-by-one connector scenario. Also, be sure to check the disk cable. Insulation sometimes rubs off of them and can lead to shorts with a myriad of symptoms. -michael NadaNet 3.1 for Apple II parallel computing!
