If your computer does not recognize the autoloader, you may need to load the appropriate autoloader module for your software package. 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. Do not let labels extend beyond label areas or fold over the edge of a cartridge. Do not place any labels on the autoloader magazine, since this may cause the tape mechanism to jam. Caution Loading cartridges in a magazine Use only approved DDS cartridges in the Scorpion 240. Make sure that the cartridges and magazine are write protected or write enabled, as necessary. Hold the magazine so that the slot numbers on the side of the magazine are right-side-up. Insert the cartridge into the magazine with the door facing toward the magazine slot, as shown in Figure 12. 2. 3. Cartridge door Figure 12. Inserting a cartridge into the autoloader magazine 24 Scorpion 240 Product Manual 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. Insert the magazine into the autoloader with the triangles facing into the autoloader bay, as shown in Figure 13. Gently push the magazine into the autoloader bay until the autoloader mechanism senses the magazine and pulls it inside. 4. Figure 13. Loading a magazine into the autoloader Ejecting a cartridge or magazine To eject the magazine from the autoloader, press the Eject button. If a cartridge is in the drive, the LCD display shows the message "EJECT?Press the Enter button, and wait for the following events to complete: 1. If the tape cartridge is not write-protected (read-only), the operating system writes the updated copy of the tape log back to the tape. The magazine is ejected. If there is no cartridge in the tape drive, the magazine is ejected without delay. 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. 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. If you force an eject, the cartridge may become unreadable and may require erasing or re-initializing by the application software. You can also force an eject when you need to eject the magazine and there is no cartridge loaded in the drive. If you force an eject when a cartridge is not loaded, the autoloader waits 35 seconds, ejects the magazine, and then resets as though it had been turned off and then turned on. To force an eject, hold down the Eject button for at least five seconds, then release the button. When you force an eject, the following occurs: If there is a tape in the drive, the Status Panel displays the message "UNLOAD TAPE X" (where X is the number of the magazine slot which held the tape currently in the drive). [. . . ] This increases the amount of data that can be stored on a finite medium and increases the overall storage efficiency of the system. With data compression, the redundant information in a data stream is identified and then represented by codewords or symbols, which allow the same data to be recorded in a fewer number of bits. These symbols or codewords point back to the 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. [. . . ]
