FN: A1—grp.frm.seq.
PAGE 43
RA7x/SA7x Pocket Reference Guide 37 0A—SDI Command Opcode Parity Error Error Description: The opcode in a level 2 SDI command was received with incorrect parity. The opcode byte must be even parity. FN: B3—inc.opc.prty—incorrect command opcode parity Most Probable Cause: ECM, SDI controller, SDI cable 0B—Invalid Opcodes Error Description: One of two conditions have been detected: • The opcode received in the level 2 command was not one of the 16 possible opcodes.
PAGE 44
38 RA7x/SA7x Pocket Reference Guide 0E—Real-Time Command Contains Invalid Head Address Error Description: A real-time command is one of the SDI level 1 data transfer commands. If the low byte of any of these commands indicates an invalid head, this error occurs. FN: A2—inv.grp.num.
PAGE 45
RA7x/SA7x Pocket Reference Guide 16—Guard Band Error Error Description: During normal operation, the heads have moved into the inner or the outer guard band area. If the servo system is in the process of loading or unloading heads (for example: the positioner is moving from the landing zone or to the landing zone), the I/O processor will mask out the guard band signals internal to the GASP gate array and thus prevent a servo fault from occurring. FN: 46—out.grd.bnd.—outer guard band fault FN: 47—inn.grd.
PAGE 46
40 RA7x/SA7x Pocket Reference Guide 17—Invalid or Inconsistent Parameters Error Description: One or more of the parameters sent by the controller as part of the level 2 command is invalid or inconsistent.

PAGE 47
RA7x/SA7x Pocket Reference Guide 41 18—Opcode/Parameter Invalid/Inconsistent with Drive State Error Description: The level 2 command received from the controller is valid, but the command itself or a parameter contained in the command is inconsistent with the drive’s current state or physical status. FN: 68—asup.bkd.ctrl.—spinup blocked by the controller FN: 69—sup.bkd.dgn.—spinup blocked by diagnostic FN: B4—inc.cmd.flt.—incorrect command drive fault state FN: B5—inc.cmd.lsn.

FN: 51—sct.ovr.run.—sector over run Most Probable Cause: ECM, SDI controller, SDI cable, HDA 25—Off Track Error Error Description: During track following mode, the DSP processor determined that the read/write heads are not within track center line tolerances. FN: 4D—svo.off.trk.
PAGE 49
RA7x/SA7x Pocket Reference Guide 43 28—Module Over Temperature Error Error Description: Sensing circuits on the ECM have detected temperatures that exceed the maximum allowed for safe and reliable operation. FN: 4E—snk.ovr.tmp.—heat sink assembly over temperature FN: 3C—xep.ovr.tmp.—module exception over temperature error FN: 3D—com.ovr.tmp.—module common over temperature error Most Probable Cause: SA7x fan, ECM, HDA. Be sure that the disk is operating within the environmental specifications.
PAGE 50
44 RA7x/SA7x Pocket Reference Guide 33—Attempt to Write Through Bursts Error Description: The read/write heads were over the embedded burst area of the sector, and the internal write gate was asserted. FN: 53—wrg&brt.prt.—write gate and burst protection both asserted Most Probable Cause: SDI controller, ECM, SDI cable NOTE See Table 9 and verify the minimum controller revision.
PAGE 51
RA7x/SA7x Pocket Reference Guide 45 3A—Write and Write Protected Error Description: The drive was write protected and detected the assertion of the internal write gate. FN: 59—wrg&wrt.prt.—write gate and write protection both asserted Most Probable Cause: ECM, SDI controller, SDI cable 3B—AGC Fault Error Description: Either the automatic gain control (AGC) circuit has failed or read signal amplitude variations have far exceeded the capability of the AGC circuit to maintain a proper signal lock.
PAGE 52
46 RA7x/SA7x Pocket Reference Guide 43—TCR and R/W Ready Out L Error Description: Transfer command received (TCR) and read/write ready out L indicates the drive received a data transfer command and read/write ready was not asserted. FN: 50—tcr&r/w.rdy.
PAGE 53
RA7x/SA7x Pocket Reference Guide 47 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.
PAGE 54
48 RA7x/SA7x Pocket Reference Guide 60—Read/Write Head Select Failure Error Description: One of two conditions occurred. While trying to select a specific head to read or write, the DSP detected a soft servo fault and as such could not complete the head switch operation, or the I/O processor timed out waiting for the DSP to complete the head switch operation. Realize that if the drive detects any other faults, these faults are reported with the real-time error code associated with the error. FN: F2—inv.
PAGE 55
RA7x/SA7x Pocket Reference Guide 49 61—Drive Capacity Configuration Error Error Description: One of two conditions occurred. Either the HDA capacity indicator switch on the RA71/RA72 disk drive was set incorrectly, or the ECM logic cannot determine whether the HDA is an RA71 disk drive (700 MB storage capacity) or an RA72 disk drive (1 GB storage capacity).
PAGE 56
50 RA7x/SA7x Pocket Reference Guide 62—Read Failure Error Description: One of six possible conditions occurred during the diagnostic read section of the test. The six conditions are: • Invalid sector number • Expired sector timer • Expired read sector timer • Incorrect read sector • Read diagnostic failure • Incorrect sector error count FN: F4—inv.dgn.sct.—invalid diagnostic read sector number FN: F6—inv.dgn.rsf.—invalid diagnostic read sector fault FN: F7—exp.dgn.rds.
PAGE 57
RA7x/SA7x Pocket Reference Guide 51 67—Write Failure Error Description: One of five possible conditions occurred during the diagnostic write section of the test. The five conditions are: • Invalid sector number • Expired sector timer • Expired write sector timer • Incorrect write sector • Write diagnostic failure FN: F9—inv.dgn.wsn.—invalid diagnostic write sector number FN: FB—inv.dgn.wsf.—invalid diagnostic write sector fault FN: FC—exp.dgn.wrs.
PAGE 58
52 RA7x/SA7x Pocket Reference Guide 86—Internal RAM Failure Error Description: If during any data verification process the data stored in the processor internal RAM location does not match the data that was written to that location, the test is terminated and this error is reported. FN: E4—inv.ram.mem.—invalid internal static RAM memory Most Probable Cause: ECM 87—UVPROM Checksum Failure Error Description: This test calculates a checksum by adding, without carry, all the locations of the UVPROM.
PAGE 59
RA7x/SA7x Pocket Reference Guide 53 89—EEPROM Failure Error Description: The I/O processor has detected a failure with the EEPROM memory used to store drive internal error log entries. FN: 41—inv.log.fmt.—invalid EEPROM error log format FN: 42—exp.pwc.tmr.—expired EEPROM page write cycle timer FN: 43—inc.pwc.dat.—incorrect EEPROM write page cycle data FN: 44—exp.bwc.tmr.
PAGE 60
54 RA7x/SA7x Pocket Reference Guide 8D—External Loop Back Failure Error Description: External loop back failure occurs if the signal Init Req H should be asserted and it is not, or if it should not be asserted and it is. FN: EA—ext.lop.tst.—invalid external loop back test Most Probable Cause: ECM 94—Loop Back Frame Not Received Error Description: Non-transfer command received (NTCR) did not become asserted after an SDI frame was sent. FN: E7—int.lop.tst.
PAGE 61
RA7x/SA7x Pocket Reference Guide 55 9A—Read and Off Track Error Description: The heads were not finepositioned or locked on track (relative to the embedded servo information) at the time a read operation was ready to start. The drive took the necessary actions to establish the on-track condition. The drive will not post a recoverable read-and-off-track error to prevent interruption to the controller.
PAGE 62
56 RA7x/SA7x Pocket Reference Guide C6—PLO Failure Error Description: The VCO clock is not in sync or has fallen out of sync with the rotating disk. FN: 48—plo.lck.flt.—PLO lock failure Most Probable Cause: HDA, ECM C9—Analog Loop Failure Error Description: There are three possible conditions that result in analog loop failure: • The I/O processor could not complete a write to the GASP gate array mailbox. • The I/O processor could not complete a read of the GASP gate array mailbox.
PAGE 63
