Off On

Reserved. Default is no jumper installed.

TP TP

(Not applicable to "WC/DC" model drives)

Off Off

No terminator power is connected to drive

 

terminators or SCSI bus I/O pin 26.

On Off

Drive supplies its own terminator power only.

 

Jumper on this position is factory default.

Off On

Drive supplies power to I/O pin 26 of SCSI

 

bus; none to internal terminators. When

 

drives have differential I/O circuits a jumper

 

on the right TP position may be needed to

 

power external terminator (see system docu-

 

mentation). The "WD" drive has differential

 

I/O circuits which have no terminator circuits

 

on the drive. The "WC/DC" Model drives

 

have no provisions for terminators on the

 

drive and no provisions for terminator power

 

on the 80 pin I/O connector.

On On

Drive supplies terminator power to itself (in-

 

ternal connection) and to I/O pin 26 of SCSI

 

bus. This is a legal jumper setting.

Off

See above explanations for TP jumpers.

TP Position A

On This horizontally positioned jumper across the two TP positions nearest PCB edge, connects terminator power from SCSI bus

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.
