Page 29: Operation
4. Operation 4.1. Summary of LED indications The SDX-700C have 3 LEDs. Each LED shows "Tape Motion", "Cleaning Request", and "Replace Tape" as defined. "Tape Motion" to show the tape motion in the drive. "Cleaning Request" to be on, when CLEANING is required.
Page 30: Operator Action
Powering up the SDX-700C After the initial installation of the SDX-700C has been verified, power can be applied to the unit. The +12V and +5V power must be applied simultaneously. (See Figure 2-5) The SDX-700C will execute a power-up diagnostic and then comes ready.
Page 31: Write-Protecting Cassettes
In the case of two partition tape the drive detects that the tape has been formatted as a two partition tape when the Reference Area is read during the load sequence. When the Unload operation begins the drive will then automatically update the Tape Log for each partition before unloading the tape. SONY AIT-3 drive SDX-700 series Ver.2.1...
Page 32: Power-Fail Or Scsi Reset Handling
(1) The drive remains positioned at the point where the power-fail or SCSI Reset occurred. (2) It executes the Power-Up sequence of self-tests. (When power is restored.) (3) If a tape is in the drive, the SDX-700C starts a LOAD sequence. The drive rewinds the tape to BOT and remains on-line.
Page 33: Normal Status Display
Normal Status Display 4.3.4.2. After the Diagnostic Display, when no failures are detected, the SDX-700C is in the Normal Status. The LEDs show various Normal Status (No Error) indications as shown in the table below: Table 4-2: Normal LED indications...
Page 34: Tape Partitions
Head Cleaning 4.6.1. The SDX-700C has a built in head cleaning function that helps prevent/recover from head contamination problems which eliminates the need for periodic head cleaning with a head cleaning cassette as required with other tape formats. However, severe cases of contamination from which the drive can not recover may require use of a cleaning cassette.
Page 35: Troubleshooting Guide
Request is indicated by the Cleaning Request LED. Troubleshooting Guide 4.6.2. Problems encountered while operating the Sony SDX-700C tape drive fall into two categories: Operational problems and Read/Write problems. Operational problems include any conditions that prevent the tape drive from operating. Operational problems usually are discovered the first time the drive is installed on a system or when the system configuration is changed or physically moved.
Page 36 Locate the small opening in the bottom of the drive and insert the tip of a precision screwdriver so that the Threading motor shaft can be rotated. Rotate the motor shaft counterclockwise to bring the threading mechanism back to the initial position. SONY AIT-3 drive SDX-700 series Ver.2.1...
Page 37 Return the drive to Sony for repair. The drive powers up properly and loads and unloads tapes but will not respond to any SCSI commands.
Page 38: Replace Tape
- Clean the drive with the AIT cleaning cartridge. - Load a new tape in the drive. - Retry the operation. Note: If these steps do not correct the problem the drive may be defective and should be returned to Sony for service. Media Warning 4.6.2.3.
Page 39: Scsi Interface
5. SCSI Interface 5.1. Introduction The Sony SDX-700C uses the SCSI interface to connect to the host system. The Small Computer System Interface (SCSI) is an industry standard interface, approved by the American National Standards Institute (ANSI). It is recommended that this document be used along with the ANSI standard document. The ANSI specification defines the interface in general while this document describes the specific implementation for this unit.

Page 42: Message Specification
The table below lists the Messages supported by the SDX-700C. The SDX-700C supports the Synchronous Data Transfer Request Extended Message, and the Wide Data Transfer Request Message.
Page 43: Extended Message (01H)
For double transition (DT) synchronous data transfer the REQ/ACK OFFSET is the maximum number of REQ transitions allowed to be outstanding before a corresponding ACK transition is received at the target. The size of a data transfer shall be 2 bytes. SONY AIT-3 drive SDX-700 series Ver.2.1...
Page 44: Synchronous Data Transfer Request(01H)
Transfer period is the minimum time allowed between leading edges of successive REQ pulses and of successive ACK pulses. The SDX-700C supports the following transfer periods: SONY AIT-3 drive SDX-700 series Ver.2.1...
Page 45 ACK pulse is received at the target. A REQ/ACK offset value of ZERO shall indicate asynchronous data transfer mode. The SDX-700C supports synchronous data transfer REQ/ACK offset values from 1 to 15. The originating device (the device that sends the first of the pair of SDTR messages) sets its values according to the rules above to permit it to receive data successfully.
Page 46: Wide Data Transfer Request

Additional Partitions Defined field, PSUM and Partition Size field. The SDX-700C allows the tape to be split into two entirely separate and independent partitions like DDS format. Each partition will have its own Reference, System and Vendor Group area. The maximum size of a partition will be the whole tape.
Page 100 A second way to issue Mode Select Page 11h is to set Page Length to 08h, and set bytes 8 and 9 to partition 1 size. In this method partition 0 size is not sent, but this size is still computed as defined above. In either case, Mode Sense will report partition 0 and partition 1 sizes. 6-50 SONY AIT-3 drive SDX-700 series Ver.2.1...
Page 101: Medium Partitions Parameter
MIC, as well as the AIT Format limit of 256 partitions. SDX-700C calculates how many partitions can be created for the current SDX1-25C media; for example, you can make up to 14 partitions with net total 13 bytes of the User Volume Note and User Partition Notes when using 2Kbytes version of SDX1-25C.
Page 102 The Partition Size specifies the capacity of all partitions in Megabytes (in the case of SDX-700C - see PSUM field definition). The drive rounds the Partition Size to the next whole group value and then applies an algorithm which allows for the writing of ECC-3 frames and for RAW error recovery so as to reserve sufficient physical space on the media for the specified capacity.
Page 103 Capacity belongs to Partition 0. Note 1: SDX-700C accepts any number including 0FFh for the Parameter List Length in CDB, although the drive returns valid information only. For example, in case of a single partition, SDX-700C returns 16h bytes of parameter list (sufficient for one partition size descriptor), even if the host sets 0FFh for the Parameter List Length in CDB.

The Append Partition Command is available in the AIT mode. The Append Partition Command takes effect if the current partition is the last partition. When the command is issued in the last partition, SDX-700C will automatically space to the EOD area find the bottom of the Device Area, and then create a new partition. If the command is issued in any other partition, SDX-700C will return the CHECK CONDITION status (83h/97h Current Partition is no the last partition).

Page 204: Mode Select Page 33H (Delete Partition)
With the tape already loaded, and with partition 4 active, the Delete Partition command issued with the Indicated Partition Number set to 4 will delete partition 5. SDX-700C will change the value of 5 in the Last Partition Number field in the Volume Information in MIC to 4. No tape motion will take place. The new last partition - partition 4 - will become open-ended, spanning up to the OEM.
Page 205 With the tape already loaded, and with partition 0 active, the Delete Partition command issued with the Indicated Partition Number set to 0 will delete partitions 1, 2, 3, 4, and 5. SDX-700C will change the value of 5 in the Last Partition Number field in the Volume Information in MIC to 0.
Page 206 With the tape already loaded, and with partition 1 active, the Delete Partition command issued with the Indicated Partition Number set to 3 will delete partitions 4 and 5. SDX-700C will change the value of 5 in the Last Partition Number field in the Volume Information in MIC to 3.
Page 207 Note 7: Delete Partition command deletes partitions with ODA. Note 8: If the WP tab is set we do not allow Delete Partition Page. Note 9: Delete Partition page should write all buffered data to tape, then delete partition. SONY AIT-3 drive SDX-700 series Ver.2.1 14-11...

RD_R: If this bit is set to ONE then prevent read-retry for the Partition. (Sense Only bit) If this bit indicates 1 then the Partition is still opened. This bit always managed by SDX-700C, and cannot modify by others. The WR is equipped as logical write-protection tab. The RD is equipped as logical read-protection tab. You can control retry action for each partitions by setting WR_R and RD_R.

MIC, as well as the AIT Format limit of 256 partitions. SDX-700C calculates how many partitions can be created for the current SDX MIC media; for example, you can make up to 14 partitions with net total 13 bytes of the User Volume Note and User Partition Notes when using 16 kbits version of SDX1-25C.

Page 211 14. Appendix G The SDX-700C operating in the AIT Format Mode allows tapes to be split into separate and independent partitions, each with its own Reference, System and Vendor Group areas. The maximum size of a partition may be the entire tape.
Page 212 The Partition Size specifies the capacity of all partitions in Megabytes (in the case of SDX-700C - see PSUM field definition). The drive rounds the Partition Size to the next whole group value and then applies an algorithm which allows for the writing of ECC-3 frames and for RAW error recovery so as to reserve sufficient physical space on the media for the specified capacity.

SDX-700C reads the tape after loading and retrieves the Partition-ID from the tape comparing it with the Partition ID obtained from the Eject Status. If the id’s are the same and the Area ID on tape is ODA, then SDX-700C concludes that the loading was successful and it clears the Position Information in MIC.
Page 217 Load here If the Position Information on tape is different from the Position Information in MIC, then SDX-700C will rewind the tape to PBOT, clear the Position Information in MIC, because the position information on tape is different from the position information in MIC), and stand by at the top of partition zero after reading the System Log information on partition zero.
