2.0 Applicable standards and reference documentation The drives documented in this manual have been developed as system peripherals to the highest standards of design and construction. The drives depend on host equipment to provide adequate power and environment for optimum performance and compliance with applicable industry and governmental regulations. Special attention must be given in the areas of safety, power distribution, shielding, audible noise control, and temper- ature regulation.

2.1.2 Electromagnetic compliance Seagate uses an independent laboratory to confirm compliance with the directives/standards for CE Marking and C-Tick Marking. The drive was tested in a representative system for typical applications. The selected sys- tem represents the most popular characteristics for test platforms. The system configurations include: • Typical current use microprocessor • Keyboard • Monitor/display • Printer •Mouse Although the test system with this Seagate model complies with

2.1.3 European Union Restriction of Hazardous Substances (RoHS) The European Union Restriction of Hazardous Substances (RoHS) Directive restricts the presence of chemical substances, including Lead (Pb), in electronic products effective July 2006. A number of parts and materials in Seagate products are procured from external suppliers. We rely on the rep- resentations of our suppliers regarding the presence of RoHS substances in these parts and materials. Our supplier contracts require complia

4.4 Prefetch/multi-segmented cache control The drive provides a prefetch (read look-ahead) and multi-segmented cache control algorithms that in many cases can enhance system performance. Cache refers to the drive buffer storage space when it is used in cache operations. To select this feature, the host sends the Mode Select command with the proper values in the applicable bytes in page 08h. Prefetch and cache operations are independent features from the standpoint that each is enabled and di

If read caching is enabled (RCD=0), then data written to the medium is retained in the cache to be made avail- able for future read cache hits. The same buffer space and segmentation is used as set up for read functions. The buffer segmentation scheme is set up or changed independently, having nothing to do with the state of RCD. When a write command is issued, if RCD=0, the cache is first checked to see if any logical blocks that are to be written are already stored in the cache from a previ
