"However, once it reaches the Timing Error Skip Instruction and Logic
Test, it fails with the following:
TIMING ERROR SKIP INSTRUCTION AND LOGIC
TIMING ERROR STATUS BIT NOT SET IN COMMAND REGISTER
TIMING ERROR DOES NOT CLEAR WRITE FLIP/FLOP "
If at this point it is doing a wrap-around test without drive activity,
then that sounds like a problem on the TD8E, rather than the drive.
