Drive configuration

Each disc drive has option select header connectors on the back, side and front where jumper plugs are in- stalled to select the way that the drive is to be config- ured or to select its ID on the I/O bus. See "Initial setup information" and see notes following Figure 3c. Some host systems have a remote drive ID selection capabil- ity.

"W/WD" family 68 pin SCSI I/O drives

On Hawk 2LP family "W/WD" drives either J6 (on the front of the drive) or J1-auxiliary (at the rear, next to the DC Power connector) may be used to set the drive ID. To avoid possible incorrect ID setting, do not use both J1-auxiliary and J6 for ID selection. The following figures show where these headers are located on the different drives covered by this manual. See notes following Figures 3a, 3b and 3c where explanations are given about the purpose of each jumper and specify the standard factory (called "default") settings of these jumpers (i.e., settings used for most common single drive application). Changes to these settings should be made only if it is known that the system requires a different configuration.

ST31230DC, ST31230W, ST32430W, ST31230WD, ST32430DC specifications

Seagate, a pioneering force in the hard drive industry, introduced a series of SCSI disk drives in the early 1990s, notably the ST32430WC, ST32430WD, ST31230WC, ST32430DC, and ST31230WD. These drives showcased innovative features and cutting-edge technology for the era, establishing a benchmark for performance and reliability.

The ST32430WC and ST32430WD are notable for their high-performance capabilities. With a storage capacity of 2.1 GB, these drives were designed primarily for workstations and servers. They utilized a fast 10,000 RPM spindle speed, enabling quick data access and improved data throughput. The "WC" and "WD" designations indicate SCSI interface types, with the "WC" models featuring Wide SCSI support, offering increased data transmission rates. Additionally, the drives implemented Seagate's advanced error correction and data integrity technologies, which ensured reliability for enterprise applications.

On the other hand, the ST31230WC and ST31230WD offered similar specifications but came with slightly different capacities, reaching up to 1.0 GB. Like their higher-capacity counterparts, these drives provided wide interface capabilities and boasted robust error correction features. Their reliability and performance made them ideal for small servers and high-performance workstations where quick access to data was a crucial requirement.

The ST32430DC, or the "DC" model, was designed with a focus on different enterprise applications. This variant exhibited a dual-port SCSI interface, allowing for connectivity to multiple systems. This feature made it highly suitable for multiprocessing environments, where uptime and data access rates are paramount. The drive's design was geared towards high-availability systems that required redundancy and consistent performance.

All these models leveraged Seagate's commitment to building high-reliability drives with extended lifespans. They were equipped with advanced thermal management features, ensuring stable operation even under heavy workloads. This technological foundation, combined with superior craftsmanship, positioned Seagate as a leader in the SCSI market during this pivotal time in computing history.

As the technology landscape has evolved, the ST32430 and ST31230 series may now be considered retro, but their legacy remains significant. They paved the way for modern storage solutions, and their development reflects a crucial period in the evolution of data storage technology. The foundational principles established in these drives continue to influence the design and functionality of today's advanced storage systems.
