Seagate Technology ST31051N hard drive specifications

Seagate Hawk 2XL - hard drive - 1.06 GB - Fast SCSI

The Hawk 2XL Family drives feature a new cost-optimized HDA, reduced cost SCSI code, reduced header fields and the use of innovative technology in the embedded servo, R/W heads, read circuits and SCSI controller. The Hawk 2XL Family 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 the power is removed. The Hawk 2XL Family drives incorporate an automatic shipping lock which prevents potential damage to the heads and disks that result from movement during shipping and handling. The shipping lock is automatically disengaged when power is applied to the drive and the head load process begins. The Hawk 2XL Family drives decode track location from the servo data embedded on each surface to eliminate mechanical transducer adjustments and related reliability concerns. The Hawk 2XL Family drives use a high performance actuator assembly that consists of a low inertia, balanced, patented, straight arm design that provides excellent performance with minimum power dissipation.
