1.0 Introduction This manual describes the functional, mechanical and interface specifications for the following Maxtor® DiamondMax® 21 PATA model drives: STM3320820A STM3300620A STM3250620A STM3250820A STM3200820A STM3160215A STM380215A These drives provide the following key features: • 7,200-RPM spindle speed • High instantaneous (burst) data transfer rates (up to 100 Mbytes per second) using Ultra DMA mode 5. • Tunneling magnetoresistive (TMR) recording heads and EPRML technology, 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. • 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 Read Multiple and Write Multiple commands. • Support for autodetection of master/slave drives that use cable select (CSEL).
