80 MB SCSI Hard Drive (250-4160A) Error Codes Faxback Doc. # 4991 * The 40/80-megabyte SCSI hard disk drive is a 3.5" form-factor Winchester fixed disk drive. * The 40/80-megabyte SCSI hard disk drive is compatible with the industry- standard (ANSI) SCSI host interface. * The 40/80-megabyte SCSI hard disk drive features an automatic shipping lock (AIRLOCK*) that disengages when the drive is powered on and engages when power is removed. Note: Do not move the drive for 20 seconds after DC power is removed, to make sure the actuator is completely locked. * The standard drive select setting preset at the factory configures the 40/80-megabyte SCSI hard disk drive as the primary (first) disk drive. The standard terminator setting configures the hard disk drive as the primary disk drive. Possible pin settings for the 40/80-megabyte SCSI hard disk drive are shown in the following chart. Quantum ProDrive 40S/80S The ProDrive 40S and 80S have six pairs of configuration pins that are functionally the same on both models. SCSI BUS DEVICE IDENTIFICATION (A0, A1, and A2) - These three pairs of pins comprise a 3-bit binary number in which A2 is the most significant bit and A0 is the least significant. Jumper installation represents a one, meaning that with all three jumpers installed, the device is identified as SCSI ID 7. With no jumpers installed, the device is identified as SCSI ID 0. The factory setting is SCSI ID 0, no jumpers installed. The A1 and A2 jumpers are partially installed from the factory for shipping purposes only and should be removed before installation. WAIT SPIN (WS) - The WS jumper determines whether the drive will immediately apply power to the drive motor at power-up. With this jumper installed, the motor in the hard disk drive will not spin-up until the host sends a start/stop command across the SCSI bus. If WS is not installed, the motor will immediately start spinning when power is applied. The factory setting is WS not installed, the motor will spin immediately on power-up. ENABLE PARITY (EP) - The EP jumper determines whether data across the SCSI bus will be checked for parity. If EP is installed, parity is checked; with EP removed, no parity checking is performed. The factory setting is EP installed, parity checking enabled. SELF SEEK (SS) - The SS jumper is provided as a method to continuously exercise the actuator of the drive. With the SS jumper installed, the drive will perform random seek patterns, and communication with the SCSI bus will be cut off. The factory setting is SS not installed, no self seek test. The ProDrive disk drives contains three resistor networks in sockets, to terminate the SCSI bus. Be sure the three resistors are installed to configure the hard disk as the primary drive. Remove the resistors to use the 40/80-megabyte hard disk drive as the secondary drive. SENSE ERROR CODES Sense Additional Key Sense Code (hex) (hex) Description 0 NO SENSE. Indicates there is no specific sense key information to be reported. 00 No additional information. 1 RECOVERED ERROR. Indicates that the last command was completed successfully with some recovery action performed by the ProDrive. Details may be determined by examining the additional sense bytes and the information bytes. 00 No additional information 02 Recovered seek timeout 10 Recovered CRC error 11 Recovered data ECC on last retry 13 Recovered data sync timeout 14 Recovered no record found 15 Recovered seek error 16 Recovered data marker not found 17 Recovered data ECC with retries 18 Recovered data ECC error 86 Recovered unexpected sequencer error 95 Recovered SOLO timeout 96 Recovered bump 97 Recovered underrun/overrun error 98 Recovered timeout in settling A8 Spurious nmi interrupt AB Requested format not available 2 NOT READY. Indicates that the ProDrive cannot be accessed. Operator intervention may be required to correct this condition. 00 No additional information B0 Drive recalibrating B1 Drive not up to speed B2 Drive waiting for command to start 3 MEDIUM ERROR. Indicates that the command terminated with a non-recovered error condition that was probably caused by a flaw in the medium or an error in the recorded data. 00 No additional information 10 All IDs have CRC errors 11 Uncorrectable data error 13 Data sync timeout 14 No record found 16 Data marker not found 19 Bad defect list 1C No primary defect list found 31 Format failed or not formatted 32 No more spares available 80 Can't write system sector 81 Can't read system sector 95 SOLO timeout 97 Underrun/overrun error A3 Reassign Blocks READ failure AA Reallocated uncorrectable data read 4 HARDWARE ERROR. Indicates that the ProDrive detected a non-recoverable hardware failure while performing the command. 00 No additional information 01 No index signal 02 Seek timeout 03 Write fault 06 Recalibrate failure 09 Servoing error 15 Seek error 1B Synchronous request error 32 Defect list is full 40 Buffer RAM failure 41 ECC failure 42 Power-on failure 43 Message reject 44 Firmware error 45 Reselect timeout 82 No digital P1 or P2 signal 83 Analog P1 or P2 are bad 84 Failure writing to format parameter RAM 85 Rejected message was not sent 86 Unexpected sequencer error 87 A and B servos not equal 88 Airlock stuck closed 89 Bad head amplifier 8A Bad head select 90 Synchronous acknowledge error 91 FIFO unload error 92 FIFO load error 93 FIFO predicted full error 94 Undocumented SPICY error 96 Bump timeout 98 Timeout in settling 99 Bump retry counter expired 9D Motor never gets up to speed 9E Motor drops out of legal speed range 9F Internal ROM checksum error A0 External PROM checksum error A1 Sequencer rollover register failure A2 External RAM failure A4 Bad thermistor A6 A and B servos not detected A7 Offtrack timeout A9 SOLO DMA pointer error AC Airlock stuck open AD No servo interrupt 5 ILLEGAL REQUEST. Indicates that there was an illegal parameter in the command descriptor block of in the additional parameters supplied as data for a command. 00 No additional information 19 Entered defect list in error 1A Parameter overrun 20 Invalid command 21 Invalid LBA 22 Illegal function for device type 24 Illegal field in CDB 25 Invalid LUN 26 Illegal field in parameter list 8A Invalid head 8B Invalid cylinder 8C Select from same initiator while active 8D Bad BPB/BPS 8F Invalid sector 9B Invalid period or offset in sync message 9C Active initiator attempted another select A5 Defect list out of order 6 UNIT ATTENTION. Indicates that MODE SELECT parameters have been changed by another initiator, or the ProDrive has been reset by one of the following: 1) BUS DEVICE RESET MESSAGE 2) "Hard" RESET condition (RST asserted) 3) POWER ON RESET 00 No additional information 29 Drive reset 2A Mode select parameter changed 8E Unexpected SCSI interrupt occurred 9A Target attempted to reselect ProDrive B ABORTED COMMAND. Indicates that the ProDrive aborted the command.
