     I'm having trouble installing a second hard drive in my DTK 386 PC.

Equipment:
     Adaptec ACB-2372B hard/floppy controller
     Seagate ST4144R 122 meg hard drive
     Microscience HH-1060 65 meg hard drive
     Hard drive cable with "twist" for drive C

Symptoms:
     I can set up and run either drive alone as C with no problems.
     When I have both drives installed, any operation on the Seagate will
     report "Seek error, sector not found" after a write operation on the
     Microscience drive.  This error occurs with the Seagate configured as
     either drive C or D and is consistently repeatable.  A warm boot or
     system reset will not clear the error; the Seagate will remain unusable
     until I turn the machine completely off and back on.  As long as I do
     no writes on the Microscience drive, the Seagate will work properly.

Other:
     Both drives were low level formated by the ACB-2372B.  I've
     tried using the drives with and without 17 sector translation
     enabled.  The Seagate uses a terminating resistor pack and
     the Microscience uses termination switches; according to each
     drive's documentation, I'm setting these correctly when I
     move the drives between C & D.

     I'd appreciate any help in solving this problem.  Thanks.
