Introduction
This manual describes the functional, mechanical and interface specifi-
cations for the Medalist8641 (ST38641A), Medalist 6531 (ST36531A),
Medalist 4321 (ST34321A), Medalist 3221 (ST33221A) and Medalist
2110 (ST32110A). These drives are referred to throughout this manual
by their model numbers. These drives provide the following key features:
•Low power consumption
•Quiet operation
•Support for S.M.A.R.T. drive monitoring and reporting
•High instantaneous (burst) data-transfer rates (up to 33.3 Mbytes per
second) using Ultra DMA mode 2
•Full-track multiple-sector transfer capability without local processor
intervention
•128-Kbyte cache
•State-of-the-art caching and on-the-fly error-correction algorithms
•Support for Read Multiple and Write Multiple commands
•Support for autodetection of master/slave drives that use cable select
(CSEL)
•MR recording heads and PRML technology, which provides thedrives
with increased areal density
