4D—Write and Bad Embedded
Error Description: The drive internal write gate is
asserted and embedded bursts are not valid.
FN: 54—wrg&emb.bad.—write gate and embedded
NOT OK both asserted
Most Probable Cause: ECM, HDA
4F—SDI Transmit Error—Pulse Error
Error Description: Extra or missing pulses on the SDI
write command line (data pulse error) or the RTCS line
(control pulse error) were detected.
FN: 5F—tcr&pls.err.—TCR and pulse error both
asserted (PSID)
Most Probable Cause: ECM, SDI controller, SDI
cable
50—DSP Diagnostic Timeout
Error Description: There is not a specific error code
for a failure during the initialization section of the DSP
diagnostic. However, if the DSP fails to execute the
basic initialization, it is most likely hung (or lost) and
is not able to pass an error code to the I/O processor.
It is possible that the initialization completed and the
problem is with the analog loop test. Realize that the
effect is the same: the I/O processor detects diagnostic
timeout due to the fact the DSP does not respond with
diagnostic complete or error detected.
FN: 84—exp.exc.tmr.—expired servo (DSP) execute
timer
Most Probable Cause: ECM
51—Byte/Sector Counter Failure
Error Description: Reported any time the counter is
checked and is incorrect.
FN: E5—inv.sct.ctr.—invalid sector counter
Most Probable Cause: ECM
