Scorpion 240 Product Manual 16 Parity checking (pins 9 and 10) If a jumper is installed on pins 9 and 10 (the default setting), parity checking is enabled. If no jumper is installed, parity checking is disabled, but parity is still generated by the drive. Terminator power (pins 11 and 12) Internal Scorpion 240 drives are shipped with terminator power disabled (no jumper across pins 11 and 12). You can enable terminator power, if necessary, by placing a jumper across pins 11 and 12.
Installation 17 Data compression (switches 1 and 2) If switch 1 is ON (the default setting), hardware data compression is enabled when the drive is powered on. If switch 1 is OFF, hardware data compression is disabled at power-on. If dip switch 2 is ON (the default setting) then SCSI commands can be used to enable or disable hardware data compression. To prevent hardware data compression from being enabled or disabled by SCSI commands, set dip switch 2 to OFF.

See your software installation manual for additional information. Using cartridges and magazines Applying labels When applying labels to a cartridge, observe the following precautions to prevent the cartridge from getting stuck in the autoloader: • Apply labels firmly, only in recessed label areas.
Scorpion 240 Product Manual 24 Loading a magazine into the autoloader Caution. Do not load a magazine if all the LEDs are flashing; this indicates that the drive is performing a power-on self test. 1. Make sure the drive is powered on and operating normally. 2. Hold the magazine so that the slot numbers are right-side-up. 3. Write protect or write-enable the magazine as appropriate. See page 33 for details. 4.
Drive Operation and Maintenance 25 Forcing an eject If you press the Eject button when the tape drive is busy, the tape drive first completes the current task before responding to the eject request. This way no data is lost. However, in extreme cases, you may need to force an eject to unload a cartridge, even at the risk of losing the data on the cartridge. A forced eject should only be tried when there is no other way to recover a cartridge. Caution.

Theory of operations 35 Theory of operations 5 Overview The Scorpion 240 tape drive design integrates DAT technology (helical scan recording method) into a true computer-grade data-storage peripheral with industrystandard data-compression capability. These drive designs are the result of: • Combining the economies of scale for key components, such as the cylinder, heads and signal-processing LSIs, with a computer grade drive (3.
Scorpion 240 Product Manual 36 The DDS-4 drive mechanism The Scorpion 240 uses the helical scan recording method with a four-head cylinder design. Four direct-drive motors and one brush-type motor are used in the drive. The read and write functions use LSIs. Engineering decisions—such as the modular partitioning of the electronics and use of surface mount, low power commercial and custom LSIs—allow the drives to conform to the industry-accepted 5.25-inch, fullheight form-factor.
Theory of operations 37 advantage of this design is that a RAW check is performed immediately after the data is written. As mentioned earlier, the cylinder rotates rapidly (10,000 RPM) in the same direction that the tape moves. The wrap angle of the tape on the cylinder is approximately 102 degrees. The combined movement of the tape and cylinder results in a relative headtape speed of 20.4 inches per second (ips).
Scorpion 240 Product Manual 38 Write head B 3 tape tracks Write head A 20˚ head azimuth Figure 19 Alternating azimuth angles on tape tracks Motors and control circuits The Scorpion 240 drive uses four direct-drive, brushless motors—the capstan, cylinder and two reel motors. Using these small, direct-drive motors provides maximum reliability. The cylinder motor rotates the cylinder. The capstan motor moves the tape. The two reel motors turn the tape reels.
Theory of operations 39 Flash memory Because the Scorpion 240 uses flash memory, the drive firmware can be easily upgraded when new revisions of the firmware are released. The flash memory is 1 Mbyte in size.
Scorpion 240 Product Manual 40 Excessive consecutive rewrites typically signal a degraded media condition; in these cases it is best to discontinue use of the tape in question and continue with a new tape. During a read or restore operation, the threshold level is reduced to maximize the likelihood that data can be successfully retrieved from tape.
Theory of operations 41 original data string, using fewer characters to represent the strings. Because these smaller symbols are substituted for the longer strings of data, more data can be stored in the same physical space. Some important benefits result from data compression in DAT drives: • The same amount of information can be stored on a smaller length of tape. • More data can be stored on a given length of tape. • Performance can more closely parallel to that of high-transfer-rate computers.
Scorpion 240 Product Manual 42 Qualified DDS cartridges are designed with specific write-protect, lid and other features for information interchange and are tested to comply with the ANSI DDS specifications. The Scorpion 240 drive also recognizes all MRS cartridges when MRS is enabled. MRS cartridges have a series of alternate opaque and clear stripes at the beginning of the tape. These stripes classify the media as data grade, rather than audio-grade media.
