Introduction
This manual describes the functional, mechanical and interface specifi-
cations for the ST320014A. This drive provides the following key fea-
tures:
•Low power consumption
•High instantaneous (burst) data-transfer rates (up to 100 Mbytes per
second) using Ultra DMA mode 5
•Giant magnetoresistive (GMR) recording heads and GPRML technol-
ogy, which provide the drives with increased areal density
•State-of-the-art cache and on-the-fly error-correction algorithms
•Full-track multiple-sector transfer capability without local processor
intervention
•Quiet operation
•350 Gs nonoperating shock
•SeaToolsdiagnostic softwareperformsadrive self-test thateliminates
unnecessary drive returns.
•Support for S.M.A.R.T. drive monitoring and reporting
•Support for drive self-test (DST) with S.M.A.R.T. Execute Off-line
Immediate
•Support for Read Multiple and Write Multiple commands
•Support for autodetection of master/slave drives that use cable select
(CSEL)
