  • Page 21: Data Transfer Rate

    2.Specification Data transfer Rate 2.3.2. 2.3.2.1. Sustained Data Transfer Rate to and From the Tape The sustained transfer rate to and from the tape is 6Mbyte per second with AIT-E Turbo and AIT-1 Turbo cassette , 4Mbyte per second with AIT-1 cassette. For this sustained rate to be achieved, the drive must be streaming. There may be some dependency on the host for this to be achieved.

If the SCSI command PREVENT ALLOW MEDIA REMOVAL (with Prevent bit set to one) has been sent to the drive, the cartridge will be retained in the drive even after an UNLOAD command. The EJECT button is also disabled. Send an PREVENT ALLOW MEDIA REMOVAL (with prevent bit clear)command, issue a SCSI bus reset, or power the drive off and back on to override this condition.

  • Page 41: Read/Write Problems

    4.Operation (B) If SCSI bus reset causes the drive to reset then the problem is with the SCSI bus addressing or termination. - Check that the SCSI bus ID jumper is set for the proper address (see clause 3.1.1) - Check SCSI bus termination. The two SCSI devices at the ends of the bus should be terminated. No other units should have terminators installed Note: The strength of the SCSI bus signals can be affected if too many terminators are installed (Signal drivers can be damaged as well)

    5.SCSI Interface 5. SCSI Interface 5.1. Introduction The Sony SDX-450V 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.

  • Page 45: Disconnect

    5.SCSI Interface The Host attempts to select the target by asserting SEL and releasing BSY. The Host maintains its ID and asserts the target’s ID on the data bus. Each target then checks the data lines. If the target’s ID matches that on the data bus, it accepts selection by asserting BSY.
  • Page 46: Message Specification

    5.SCSI Interface When doing a large data transfer, the target may choose to divide the entire transfer into several smaller transfers. This allows the target to free the SCSI bus whenever it needs to perform its own system tasks not immediately related to the actual data transfer over the SCSI bus.
  • Page 47: Extended Message (01H)

    5.SCSI Interface EXTENDED MESSAGE (01h) 5.3.2. 5.3.2.1. SYNCHRONOUS DATA TRANSFER REQUEST(01h) This is sent by either the initiator or the target as the first byte of a multiple-byte message. When acting as an initiator, the unit will not send any Extended Messages. No Vendor Unique codes are implemented and only the Synchronous Data Transfer Request code is supported.

  • Page 50: Save Data Pointer (02H)

    5.SCSI Interface SAVE DATA POINTER (02h) 5.3.3. This message is sent from a target to the initiator at the end of a Data Phase to request that the initiator save a copy of the present active data pointer for the currently attached logical unit. The unit will accept this message when in the initiator mode.
  • Page 51: Abort (06H)

    5.SCSI Interface 5.3.7. ABORT (06h) This message is sent from the initiator to the target to clear the present operation. All pending data and status from the affected logical unit is cleared, and the target goes to the BUS FREE phase. This message can be sent to a logical unit that is not currently performing an operation for the initiator.
  • Page 52: Identify (80H-Ffh)

    5.SCSI Interface 5.3.12. IDENTIFY (80h-FFh) These messages are sent by either the initiator or the target to establish the physical connection path between an initiator and target for a particular logical unit. This message byte can have the following bits set: Bit 7 This bit is always set to one to distinguish these messages from other messages.
  • Page 53 5.SCSI Interface BUSY: The drive is busy. This status is returned whenever the drive is unable to accept a command from an otherwise acceptable initiator. The BUSY status will be returned by the unit, if, while it is DISCONNECTED from the SCSI bus, it receives a command from a different initiator. The unit does not stack commands and therefore will not accept the next command until the current one has completed.

In this mode, it supports up to two partitions, logically numbered 0 and 1, where the logical Partition 1 is the first physical partition on the tape. The physical partition numbering is the same in either the DDS emulation or the native AIT mode: the first partition on tape is given the physical partition number of 0.
