1.0 Introduction

This manual describes the functional, mechanical and interface specifications for the following Seagate® DB35

model drives:

DB35 Series

• ST3400832ACE

• ST3300831ACE

• ST3250823ACE

• ST3200826ACE

These drives provide the following key features:

• Minimal acoustics for consumer storage usage profile.

• Bedroom quiet performance.

• Optimized power for consumer storage devices.

• Spinup current limited to a maximum of 2 amps.

• 7,200-RPM spindle speed

• 8-Mbyte buffer on: ST3400832ACE, ST3300831ACE, ST3250823ACE and ST3200826ACE.

• High instantaneous (burst) data transfer rates (up to 100 Mbytes per second) using Ultra DMA mode 5.

• Tunneling Giant magnetoresistive (TGMR) 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.

• 350 Gs nonoperating shock.

• 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).

• SeaTools diagnostic software performs a drive self-test that eliminates unnecessary drive returns.

• The 3D Defense System™ , which includes Drive Defe nse, Data Defense, and Diag nostic Defense, offers the industry’s most comprehensive protection for disc drives.
