Notes for Figure 3a, 3b and 3c:

[1]Notes explaining the functions of the various jump- ers on jumper header connectors J2, J1-auxiliary and J6 are given below in left to right order of jumper position. The term "default" means as standard OEM units are configured when shipped from fac- tory. "Off" means no jumper is installed; "On" means a jumper is installed. Off or Onunderlined is factory default condition.

[2]The PCB on "WC" and "DC" models does not have connector J1-auxiliary, but has a single 80 pin J1 connector having combined SCSI I/O and DC power connector instead of the 68 pin SCSI I/O, 12 pin auxiliary, and 4 pin DC power connectors that "W" and "WD" models have. Included among the 80 J1 pins are the SCSI ID, Motor Start and Delayed Motor Start select functions, and the remote BUSY LED signal. Do not use J2 and J6 for these four functions if the host uses the ones included in the 80 pin J1 connector.

[3]Drive ID may be established by installing jumper plugs in one of the patterns shown in Figures 3a and 3b or by plugging onto J6 or J1-auxiliary a cable that leads to an external ID selection circuit. Jumper plugs on both J6 and J1 auxiliary, or J6 and an external ID selection source should not be used. See [4] for other functions of these two headers that are time-shared with the drive ID function.

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.
