5 PROTOCOL ERROR (PE)-Improper command codes or parameters were issued to the drive.
6 TRANSMISSION ERROR (RE)-An error occurred in the transmission of a command from the controller to the drive. The error can be a checksum error, an incorrectly formatted command string, but is most likely an SDI cabling problem.
7 DRIVE ERROR (DE)-A drive error has occurred and the drive FAULT light may be on.
17.2.4 RA81 Controller Byte
Controller byte is the high byte of word 23. The controller byte contains general status information.

A 4-bit drive status code indicating various states of a drive operation. At the present time, only the three codes listed are valid.
State Code Description 0000 Normal operation
1000 The drive is offline due to being under control of a diagnostic.
1001 The drive is offline because another drive has the same unit identifier.
4-7 SUPPRESS (S1-S4)
The drive suppressed the attention-available messages. These messages may be suppressed and are sent to the controller when the drive the Available State.

17.2.5 RA81 Retry Count
Retry count is the low byte of word 24. Some errors are retried several times before a failure is declared. The retry count is the number of retries attempted from the previous operation.
17.2.6 RA81 Last SOl Command
Last SDI command is the high byte of word 24. This byte contains the last SDI command received by the drive. SDI Commands are different than MSCP commands from the host to the controller.
For the SDI commands see Table 17-5.

17.2.7 RA81 SOl Error Status
SDI error status is the low byte of word 25. This byte contains SDI error status bits 3, 4, 5, and 7.
This error code provides information on SDI errors as seen by the drive.
• Bit 3, OVERRUN ERROR-Either a read or a write command extends past the sector or index pulse where the operation began.
• Bit 4, PARITY ERROR FOUND-A parity error is discovered during a transmission on the SDI Real-time Controller State line. The Real-time Controller State line of the SDI bus carries the following four control signals to the selected drive:
17-7
FOR INTERNAL USE ONLY RA81 DRIVE STATUS
• IN IT
• READ GATE
• WRITE GATE
• RECEIVER READY
• Bit 5, CONTROL PULSE ERROR-During the transmission of a real-time command if two or more pulses of the same polarity are detected on the SDI Real-time Controller State line.
Normally, SDI signal polarities alternate between positive and negative.
• Bit 7, DATA PULSE ERROR-Two or more pulses of the same polarity are detected in the drive on the SDI write command data line.
17.2.S RASl Current Cylinder low Byte
Current cylinder low byte is the high byte of word 25. Current cylinder low byte is the low order address bits of the last seek operation.
17.2.9 RASl Current Cylinder High Byte
Current cylinder high byte is the low byte of word 26. Current cylinder high byte is the high order address bits of the last seek operation.
17.2.10 RA81 Current Group
Current group is the high byte of word 26. This byte contains the present drive group address.
17.2.11 RASl Drive Error Code
Drive error code is the low byte of word 27. This byte contains the microprocessor error code displayed by the diagnostic terminal or LEOs after the error was detected:
