The drive address is 0 (Master or Single) if CSEL is low, or 1 (Slave) if CSEL is high. NOTE The WD Portfolio drive autodetects whether it is a master or slave when CSEL is driven low. Drive Active/Slave Present -------------------------- Pin 23 This open collector output is a time-multiplexed signal indicating drive active or slave present. At reset, this signal is an output from the slave drive and an input to the master drive, showing that a slave drive is present. For all times other than reset, DASP- is asserted by the master and slave drives during command execution. ********************************************************************** I N S T A L L ********************************************************************** WESTERN PHD1000 TECHNICAL REFERENCE GUIDE 2/12/97 79-860022-000 Notes On Installation ===================== Connectors ----------- Mating connector: AMP P/N 146375-1 or equivalent. Host Connector Pin Lengths -------------------------- The following are recommended pin lengths for the host connector. - Long (0.197 inch / 5.0 mm) - Medium (0.167 inch 4.25 mm) - Short (0.138 inch / 3.5 mm) Long pins are used for power and ground pins. Medium pins are used for all of the standard IDE interface pins. Short pins are used for Device Enable, Insert-, and Lock-. ********************************************************************** F E A T U R E S ********************************************************************** WESTERN PHD1000 TECHNICAL REFERENCE MANUAL 79-860022-000 2/12/96 General Description ------------------- The WD Portfolio Enhanced IDE hard drive provides 1.0 GB of formatted storage in a revolutionary low-profile (10.5 mm high) 3-inch form factor. It is a versatile, low-cost storage solution - ideal for use in full-size and slimline notebooks. The WD Portfolio hard drive redefines the concept of upgradable storage. Unlike other hard drives, all of the WD Portfolio's electronics are encased in a sealed system, which means you no longer have to worry about damage caused by electro-static discharge (ESD).
