The ST-4096 family drives have three jumpers which all work together
to control a write fault condition - JP2, JP5, and pins 11 & 12 of J8.
The placement of the jumpers at these locations depends on the EC#
revision of the drive logic board.

To determine the EC#, look for a four digit number which is lightly
stamped with white ink on the drive logic board, up near the front of
the drive. This number is NOT part of the printed circuit board
masking. Instead, it looks as if it was indeed placed by a hand held
rubber stamp. The orientation of these numerals, therefore, may be
either horizontal, vertical, or angled.
