General description

This section describes in essentially general terms the interface requirements supported by the Cheetah 15K.5

sidered by designers when designing a system in which this family of drives can properly operate. Seagate
declares that the drives operate in accordance with the appropriate ANSI Standards referenced in various
places herein, with exceptions as noted herein or in the Seagate Parallel SCSI Interface Manual and the SCSI
Commands Reference Manual .
