I doubt this is related, but I had a similar situation with a couple
brand new disks that I installed. Thought I would mention, JIC. Us older
folks used to store unused jumpers on pins on the HDS. A ground-to-
ground connection never did any harm. I used this same scheme on the new
disks. The bootable master had no problems. The secondary on IDE-2 did
exactly what you described. One day I got sick of it, popped it out,
noted that the pins were "undocumented" and removed the jumper.
Problem solved. *sigh* Back to Scotch taping spare caps to the HD case
and replacing the deteriorated tape every once-in-a-while.
Anyway, could you have a similar situation that is causing some long-
term effect that I did not see (either it wasn't there or my load didn't
cause it to become noticeable or I am unobservant).
