Introduction
This manual describes the functional, mechanical and interface specifications for the ST380020A, ST360020A, ST340810A and the
ST320410A. These drives provide the following key features:
8.9 msec seek time, 5,400 RPM and 2-Mbyte buffer combine for
•
excellent desktop performance
Low power consumption
•
High instantaneous ( burst) data-tr ansfer rate s (up to 100 Mbyte s 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
•
The innovative, shoc k-absorbing SeaShiel d
•
against electrostatic discharge ( ESD) and other handling d amage. It
also includes installation instructions and jumper settings.
®
cover protects the drive
SeaTools diagnostic software performs a drive self-test that eliminates
•
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)
