3.Check the other available jumper settings (optional) This drive provides several features for unique configura- tions. You will not normally need to change from the default settings for normal operation. See Figure 13 on page 34.

Single-ended mode option

You can force the drive to operate only in SE mode by installing a jumper on J2 pins 15 and 16. The default is to allow the drive to automatically detect and use SE or LVD mode. See page 11 for a description of these two modes.

Delay Motor Start and Motor Start options

You can control when the drive’s motor starts spinning the media using these two jumper positions (J2 pins 11 and 12 and J2 pins 13 and 14). You can configure the drive to delay spinning up until a certain number of seconds elapse or until the drive receives a Start Unit command from the host sys- tem. The default settings are with both off so that the drive begins spinning up as soon as it receives power.

Write Protect option

You can install a jumper connecting J2 pins 9 and 10 to pre- vent anyone from writing data to this disc drive (users can still read data from the drive). This jumper is normally left off to allow users to write data to the drive.

Parity Check option

You can disable parity checking by installing a jumpers on J2 pins 7 and 8. Most systems prefer that parity checking remain enabled. Refer to your host adapter or system docu- mentation to determine whether your host adapter supports parity checking.

ST136403LW/LC specifications

The Seagate ST136403LW/LC is a vintage hard disk drive that belongs to Seagate's esteemed lineup of storage solutions. Known for its reliability and performance during the era of its release, this model caters to various computing needs, particularly in enterprise and industrial settings.

One of the standout features of the ST136403LW/LC is its capacity of 36.4 GB, which, although modest by modern standards, was quite impressive in the early 1990s. This size made it ideal for businesses at the time looking to store substantial amounts of data without the high costs associated with larger enterprise solutions.

The drive operates at a speed of 7200 RPM, allowing for efficient data access and transfer. The spindle speed is crucial for performance, and 7200 RPM was considered rapid for hard drives in that period. This enhanced speed translates to quicker read and write times, making it suitable for applications that require timely data retrieval.

The ST136403LW/LC utilizes the SCSI interface, a popular choice in server environments for its robustness and speed. SCSI technology facilitates the connection of multiple drives, providing the ability to network various devices and manage them effectively. The multi-device capability is particularly beneficial for enterprise applications, ensuring that data centers can efficiently manage resources.

In terms of physical characteristics, the ST136403LW/LC is a 3.5-inch form factor drive, a standard size that fits into most desktops and servers of its generation. This compatibility is vital for users looking to upgrade their existing systems without the need for significant modifications.

The drive also includes built-in error correction features, enhancing data integrity and reliability, crucial for business operations where data loss can lead to substantial repercussions. Additionally, it employs a sealed enclosure design, providing protection against dust and moisture, thereby extending the drive's lifespan in demanding environments.

Furthermore, Seagate's reputation for durability is echoed in the ST136403LW/LC, as it was designed to endure the rigors of everyday use, particularly in enterprise settings where uptime is critical.

In conclusion, the Seagate ST136403LW/LC serves as an essential piece of technology from its era, characterized by its 36.4 GB capacity, 7200 RPM speed, SCSI interface, and robust construction. While modern storage solutions have far surpassed its capabilities, this drive remains a testament to Seagate's legacy in the storage industry, reflecting the innovations of its time.
