1.0 Scope ® ® This manual describes Seagate Technology LLC, Cheetah 10K.7 SCSI disc drives. Cheetah 10K.7 SCSI drives support the small computer system interface (SCSI) as described in the ANSI SCSI SPI-3 interface specifications to the extent described in this manual. The SCSI Interface Product Manual (part number 75789509) describes general SCSI interface characteristics of this and other families of Seagate drives. From this point on in this product manual the reference to Cheetah 10K.7 SCSI

2.0 Applicable standards and reference documentation The drive has been developed as a system peripheral to the highest standards of design and construction. The drive depends upon its host equipment to provide adequate power and environment in order to achieve opti- mum performance and compliance with applicable industry and governmental regulations. Special attention must be given in the areas of safety, power distribution, shielding, audible noise control, and temperature regu- lation. In par

2.2 Electromagnetic compliance Seagate uses an independent laboratory to confirm compliance to the directives/standard(s) for CE Marking and C-Tick Marking. The drive was tested in a representative system for typical applications. The selected sys- tem represents the most popular characteristics for test platforms. The system configurations include: Typical current use microprocessor 3.5-inch floppy disc drive Keyboard Monitor/display Printer External modem Mouse Although the test s

3.0 General description Cheetah 10K.7 SCSI drives combine giant magnetoresistive (GMR) heads, partial response/maximum likeli- hood (PRML) read channel electronics, embedded servo technology, and a wide Ultra320 SCSI interface to provide high performance, high ] data storage for a variety of systems including engineering workstations, net- work servers, mainframes, and supercomputers. Ultra320 SCSI uses negotiated transfer rates. These transfer rates will occur only if your host adapter supports

Cheetah 10K.7 SCSI drives use a dedicated landing zone at the innermost radius of the media to eliminate the possibility of destroying or degrading data by landing in the data zone. The drive automatically goes to the landing zone when power is removed. An automatic shipping lock prevents potential damage to the heads and discs that results from movement dur- ing shipping and handling. The shipping lock automatically disengages when power is applied to the drive and the head load process begins.

3.5.1 Programmable drive capacity Using the Mode Select command, the drive can change its capacity to something less than maximum. See the Mode Select Parameter List table in the SCSI Interface Product Manual. Refer to the Parameter list block descriptor number of blocks field. A value of zero in the number of blocks field indicates that the drive shall not change the capacity it is currently formatted to have. A number in the number of blocks field that is less than the maximum number of LBAs c
