[. . . ] This section explains how to care for tape cartridges and how to clean the drive head. Caring for tape cartridges Although minicartridge tape cartridges are ruggedly built, they must be handled with care to preserve the data that they contain. The following points are guidelines for storing and using minicartridges. · · Do not open the tape access door of the cartridge or touch the tape itself. Keep the cartridge away from sources of electromagnetic fields, such as telephones, dictation equipment, mechanical or printing calculators, motors, and bulk erasers. Do not lay cartridges on the computer monitor or on the base unit of the computer. Keep the cartridge away from direct sunlight and heat sources, such as radiators or warm air ducts. Retensioning the tape cartridge is always recommended for optimal performance, particularly after exposure of the cartridge to temperature changes or shock. Retensioning restores the proper tape tension to the media. · · · · Cleaning the drive read/write head Caution. Never clean the read/write head of the drive with anything other than a lint-free swab or an approved cleaning cartridge. Do not touch the head with anything other than a lint-free swab. To properly maintain the tape drive, you should periodically clean the read/write head. Follow these guidelines to help ensure that your drive provides long, reliable service: · · · · Operate the drive in a clean, dust-free environment. All ATAPI packet commands are transferred in PIO mode. The value in this register must be set before every ATAPI command that transfers data (including log/mode set/sense) to determine the transfer method. This register is overwritten by the drive after every command completion to present Error 458459 MOTOR DRIVE CORD Product Manual Page 33 Chapter 5 ATAPI Interface information. If you do not program this register correctly, the drive "hangs" in the BSY state. To correct this problem, reset operations. Supported ATA Commands The ATA commands are briefly described in the following paragraphs. Execute Drive Diags (90h) This command is executed regardless of the state of the DRV bit. The command causes an actual microprocessor reset (drive loses all logical position information). Power-up diagnostics are performed, and the PDIAG/DASP handshake is performed per ATA-2 specification. The master device will generate an interrupt. Idle Immediate (E1h) This command causes the device to set its Power Mode state to Idle and to generate an interrupt. Although the drive has no actual power saving features, this command is emulated for software compatibility. Standby Immediate (E0h) This command causes the device to set its Power Mode state to Standby and to generate an interrupt. Although the drive has no actual power saving features, this command is emulated for software compatibility. Check Power Mode (E5h) This command causes the device to return its Power Mode state in the Int Reason register, and generate an interrupt. If the drive is in Standby mode, this command returns 00h in the Int Reason register, otherwise this command returns FFh in the Int Reason register (indicating IDLE mode). Idle Immediate Any Other Cmd Int Reason FFh (Idle) 00h (Standby) FFh (Idle) FFh (Idle) Sleep (E6h) This command is treated as an Idle command and does NOT prevent the drive from responding to further commands.

[. . . ] Decompression--The process of restoring compressed data to its original state. Dew--Collection of moisture in a tape drive. 458459 MOTOR DRIVE CORD Product Manual Page 75 Appendix A Directory track--The track at the centerline of the tape, identified as track 254 by its Track ID frame. Glossary Disc Drive--A peripheral storage device that rotates the disk, writes data onto it, and reads data from it as instructed by a program. ECC--(Error Correction Code) Special drive generated information that can be used to correct bad blocks. ECC block--A block containing drive-generated ECC data in its data field and part of control field. [. . . ]
