Cable Select Jumper, Remote LED Connection

Cable Select Jumper

Some computers differentiate between master and slave drives using specially designed interface cables that have the line to pin 28 (the Cable Select pin) removed or cut at one connector. The connector that has pin 28 disabled is used for the slave drive. See your computer manual to determine whether your computer supports this feature. To configure your Seagate drive for cable select, place a jumper on pins E and F as shown below.

Remote LED Connection

You can connect a remote LED to pins C (–) and D (+) as shown in the figure below. Do not install a jumper on these pins. Because the jumper block uses a 0.1-inch connector, you may need to replace the current connector. Use Seagate connector part number 10562-001 or equivalent.

The Disk Manager Online Manual

Disk Manager contains an extensive online manual. This manual includes detailed installation instructions, troubleshooting and a list of master/ slave jumper settings for many popular hard drives. To view the Disk Manager online manual, insert the Disk Manager diskette into drive A and type A:\DM /H. Then press ENTER. You can also view the online manual from within Disk Manager by selecting (V)iew/Print Online Manual in the main menu.

Booting from a Diskette

If Disk Manager installs the dynamic drive overlay (DDO) to access the full capacity of your drive, the DDO must load into memory before the operating system loads. This occurs automatically when you boot from your drive. However, if you boot from a diskette, the DDO will not be loaded and you will not be able to access your hard drive. The following procedure allows you to boot from a diskette and still access your hard drive.

1Boot the computer from the hard disc (with no diskette in the diskette drive).

2When the Disk Manager banner appears on the screen, immediately press the SPACEBAR (you have about 2 seconds).

3Insert your boot diskette and press the SPACEBAR again.

If you boot from a diskette regularly, you can create a Dynamic Drive Overlay boot diskette. It loads DDO into memory, then loads the operating system. See the Disk Manager online manual for more information about creating a dynamic drive overlay boot diskette.

Basic Troubleshooting

If you have installed your drive and it does not function properly, perform the following basic checks:

Warning. Always turn off the computer before changing jumpers or unplugging cables and cards. Wear a ground strap or take other antistatic precautions while working on your computer or handling your drive.

•Verify compatibility. Verify that the host adapter and drive are appropriately matched to each other and to your computer. Refer to the relevant documentation for details.

•Check all cards. Verify that all cards are seated in their slots on the motherboard and secured with mounting screws.

•Check all connectors and cables. Make sure all ribbon and power cables are securely connected. Ribbon cables are easily damaged, especially at the connector. Try a new cable known to be good. Make sure no connector pins are bent. Verify that pin 1 on the interface cable is aligned with pin 1 on the drive and host adapter (see figures and instructions on the front of this sheet).

•Verify jumper settings. Review the instructions on this sheet and in your host adapter installation guide. Make sure all appropriate jumpers are installed or removed as necessary.

•Check your power-supply specifications. Each time you add a new device to your computer, make sure your computer’s internal power supply can support the total power demand. If necessary, consult your dealer for a new power supply.

•Verify the drive-type settings in the system setup program. The drive- type settings in the system BIOS must not exceed the physical specifications of your drive. Also, the settings must not exceed the limitations set by the operating system and BIOS.

•Check for viruses. Before you use someone else’s diskette in your system for the first time, scan the diskette for viruses.

Advanced Troubleshooting

If you have performed the preceding basic checks but the problem persists, follow these guidelines for troubleshooting specific cases.

After you install your new drive, your computer will not boot, and no error message shows on the screen.

•Check your computer manual or BIOS manufacturer to determine whether your BIOS supports drives that have more than 4,096 cylinders. If your system has this limitation, use the following procedure to configure your computer:

1Turn off your computer, open the case, and remove your new Seagate drive.

!Caution. To avoid electrostatic discharge damage to your computer or hard drive, make sure you are

well-grounded before touching the drive, cable, connector or jumpers.

2Place a jumper on pins A and B on the master/slave jumper block as shown below. This enables the alternate capacity option that causes the drive to appear to your BIOS as having a 2.1-Gbyte capacity (4,092

ST36530A, ST34520A, ST39140A specifications

Seagate has long been a cornerstone in the hard disk drive (HDD) sector, delivering storage solutions that cater to various computing needs. Among its notable offerings are the Seagate ST39140A, ST34520A, and ST36530A models.

Operating at a spindle speed of 7200 RPM, it provides rapid data access and improved overall system responsiveness. This drive utilizes an Ultra ATA/33 interface, facilitating a transfer rate of up to 33 MB/s. One of its standout features is the use of Fluid Dynamic Bearing (FDB) technology, allowing for quieter operation and enhanced longevity. This drive also includes a built-in error correction mechanism, ensuring data integrity and reliability, which are critical for both personal and business applications.

Looking toward the ST34520A, this model is also part of the Barracuda family but offers greater storage capacity at 4.5 GB. It operates at the same 7200 RPM speed but implements an Ultra ATA/66 interface, effectively doubling the data transfer potential to up to 66 MB/s. In terms of design, it incorporates advanced technology that enhances shock resistance, an essential feature for drives installed in mobile computing environments. The ST34520A was well-regarded for its efficiency, making it suitable for both desktop systems and servers that required reliable, high-capacity storage.

Meanwhile, the ST36530A serves as an excellent bridge between performance and capacity with 6.5 GB of storage. This model also maintains the 7200 RPM speed and features the Ultra ATA/33 interface, ensuring it delivers a consistent and reliable performance. Its design is tailored to meet the demands of both stationary and portable computing environments, making it an excellent choice for various applications.
