In a one- drive system, configure the drive as a master (no jumpers installed). Alternatively, you can configure the drive as a master or slave using the cable select option. To use this option, the host system and both drives must support cable select. Cable selection requires a special daisy-chain cable that grounds pin 28 (CSEL) on one of its two drive connectors. If you attach the drive to the grounded CSEL connector, it becomes a master. If you attach the drive to the ungrounded CSEL connector, it becomes a slave. To configure an ST9420 drive for cable select, install both master/ slave jumpers. Master/slave configuration -------------------------- You must establish a master/slave relationship between two drives attached to a single AT bus. You can configure a drive to become a master or slave by setting the master/slave jumpers. Alternatively, you can configure the drive as a master or slave using the cable select option. This requires a specialized daisy-chain cable that grounds pin 28 (CSEL) on one of its two drive connectors. If you attach the drive to the grounded CSEL connector, it becomes a master. If you attach the drive to the ungrounded CSEL connector, it becomes a slave. To use this option, the host system and both drives must support cable select and both drives must be configured for cable select. To configure a Marathon 420sl for cable select, install both master/slave jumpers. For the host to recognize the slave drive using the DASP- signal, the slave drive must assert the DASP- signal at power up, and the master drive must monitor DASP- at power up. Remote LED configuration ------------------------ The drive indicates activity to the host through the DASP- line (pin 39) on the ATA interface. This line may be connected to a drive status indicator driving an LED at 5V. The line has a 30 mA nominal current limit. To avoid potential damage to the drive, the host should include a resistor in the line to the LED. This resistor should have a minimum resistance of 470 ohms (1,000 to 3,000 ohms recommended). ********************************************************************** I N S T A L L ********************************************************************** SEAGATE MARATHON 420SL JUMPER SETTINGS Notes on installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ The drive will operate in all axis (6 directions). Shock ----- All shock specifications assume that the drive is mounted in an approved orientation with the input levels at the drive mounting screws. The nonoperating specifications assume that the read/write heads are positioned in the shipping zone. Note. At power-down, the read/write heads automatically move to the shipping zone. The head and slider assembly park inside of the maximum data cylinder. When power is applied, the heads recalibrate to Track 0. Operating shock --------------- The ST9420A can withstand a maximum operating shock of 10 Gs without nonrecoverable data errors (based on half-sine shock pulses of 2 or 11 msec). The optional ST9420AG version of the Marathon 420sl incorporates SafeRite shock protection and can withstand a maximum operating shock of 100 Gs without nonrecoverable data errors (based on half-sine shock pulses of 2 or 11 msec). Nonoperating shock ------------------ The nonoperating shock level that the drive can experience without incurring physical damage or degradation in performance when sub-sequently put into operation is 300 Gs (based on half-sine shock pulses of 2 msec duration) or 150 Gs (based on halfsine shock pulses of 11 msec duration). Shock pulses are defined by MIL-STD-202 F with the amplitude tolerance controlled to 5 %. Vibration --------- All vibration specifications assume that the drive is mounted in an approved orientation with the input levels at the drive mounting screws. The nonoperating specifications assume that the read/write heads are positioned in the shipping zone. Handling and static-discharge precautions ----------------------------------------- After unpacking, and before installation, the drive may be exposed to potential handling and ESD hazards. It is mandatory that you observe standard static-discharge precautions. A grounded wrist-strap is preferred. Handle the drive only by the sides of the head/disc assembly. Avoid contact with the printed circuit board, all electronic components and the interface connector. Do not apply pressure to the top cover. Always rest the drive on a padded antistatic surface until you mount it in the host system. ATA interface connector ----------------------- The drive connector is a 44-conductor connector with 2 rows of 22 male pins on 0.079-inch (2-mm) centers (see Figure 4). The mating cable connector is a 44-conductor, nonshielded connector with 2 rows of 22 female contacts on 0.079-inch (2-mm) centers. The connectors should provide strain relief and should be keyed with a plug in place of pin 20. These drives are designed to support the industry-standard MCC direct-mounting specifications. When installing these drives in fixed mounting applications, use only MCC-compatible connectors such as Molex part number 87368-442 x. For applications involving flexible cables or printed circuit cables (PCCs), use Molex part number 87259-4413 or equivalent to connect the drive to the system. Select a connector that provides adequate clearance for the master/slave configuration jumpers if the application requires the use of such jumpers. The ATA interface cable should be no more than 18 inches long. Note. The I/O connector pins may extend up to 0.010 inches beyond the edge of the head/disc assembly. ********************************************************************** F E A T U R E S ********************************************************************** SEAGATE MARATHON 420SL JUMPER SETTINGS Read before you begin --------------------- Application. This drive uses the ATA interface and is designed for IBM AT and compatible personal computers. It is intended for use with UL-listed computers or similar products. Warning. Turn off the computer (and remove the battery if you have a notebook or laptop computer) before you open the case or touch any internal components. Caution. Special training or tools may be needed to service laptop and notebook computers. In some cases, opening the case may void your warranty. Static discharge Observe the following precautions: - Before handling any components, put on a grounded wrist strap. - Use antistatic padding on all work surfaces. - Avoid static-inducing carpeted areas. - Keep the drive in its static-shielded bag until you are ready to complete the installation. Do not attach any cables to the drive while it is in its static-shielded bag. - Handle the drive by its edges or frame. - Do not touch the I/O connector pins or the circuit board. Drive handling -------------- The drive is extremely fragile_handle it with care. Do not attach labels to any part of the drive. Inspection ---------- After you are familiar with the handling precautions listed above, inspect the drive. If it appears to be damaged, call your distributor or dealer immediately. Maintenance and repair ---------------------- Seagate drives do not require maintenance. The head/disc assembly is sealed; if you break the seal, you void the warranty. Seagate customer service centers are the only facilities authorized to repair Seagate drives. Seagate does not sanction any third-party repair facilities. Configuring the drive --------------------- 1. Put on a grounded wrist strap. Wear the grounded wrist strap throughout the installation procedure. 2. Install master/slave jumpers. In a two-drive system, you need to designate one drive as the master, or drive 0, and the other drive as the slave, or drive 1. Configuring your computer ------------------------- Before your computer can recognize a new drive, you must enter basic information about the drive into the computer's longterm memory (usually a battery-powered CMOS chip). The computer's basic input/output system (BIOS) uses this information to control the flow of data to and from the drive. Note. Some newer computers can automatically determine your drive type and configure themselves appropriately at startup. Read your system manual to determine whether this applies to your computer. If so, then skip ahead to "Formatting and partitioning the drive. If your computer cannot automatically determine your drive type, you must run a system setup program to specify the number of cylinders, heads and sectors for each drive in your system. This procedure is described on the following page. The table below lists cylinder, head and sector information for the Marathon 420sl. No. cylinders 988 No. read/write heads 16 No. sectors per track 52 Total no. sectors 822,016 Bytes per sector 512 Capacity (Mbytes): BIOS calculated 400 Usable 420 To enter these drive specifications into your system BIOS, follow these steps: 1. Turn on your computer. 2. Run the system setup program. This program configures the system BIOS to recognize your drive. In some computers you run the system setup program by pressing special keys while the computer is booting up. In other computers, you can run the program from the DOS prompt. See your system manual for more information. 3. Enter your drive specifications. Within the system setup program, there are three possible ways that you can enter your drive's specifications. These are listed below in order of increasing complexity. - Select a predefined drive type. Most system setup programs provide a long list of predefined drive types. Select a drive type with specifications that match those of your drive. - Specify a custom or user defined drive type. If the system setup program doesn't list a predefined drive type that matches your drive specifications, you may be able to define a custom or user defined drive type. You can then enter your drive specifications. When you enter drive specifications for a custom or user defined drive type, the setup program should display a drive capacity less than or equal to the BIOS calculated capacity. This value is slightly lower than the usable drive capacity. - Allow your drive to emulate or translate one of the predefined drive types. If none of the predefined drive types exactly matches your drive, and your system setup program does not allow you to specify a custom drive type, your drive may be able to emulate one of the predefined drive types. Select a predefined drive type that has a capacity as close as possible to, but not greater than, the BIOS calculated capacity of your drive. Note. If you emulate a drive type with a lower storage capacity than your drive, you limit the effective capacity of your drive. For example, a 350-Mbyte drive emulating a 300-Mbyte drive will be limited to 300 Mbytes of storage capacity. If you are not sure which drive type to select, try running the FINDTYPE.EXE utility program. This program is available from Seagate's Technical Support services (on the SeaBOARD computer bulletin board). FindType compares your drive's geometry with all geometries supported by your computer's BIOS. FindType can also determine whether an exact match exists between the drive geometry and the system BIOS. If there is no match, FindType selects the closest drive type supported by your computer's BIOS. The system setup program may request information on the drive's write precomp or landing zone. However, you do not need to enter any values, since your Seagate drive does not use these parameters. Caution. Write down the drive type that you have selected and any drive specifications that you have entered. Keep this information in a safe place. You will have to reenter this data if your CMOS battery fails. Formatting and partitioning the drive ------------------------------------- Caution. Formatting or partitioning a drive that contains data may destroy all data on the drive. Before repartitioning or reformatting a drive that contains data, make sure all data on that drive has been safely backed up. Seagate Technology assumes no liability for lost data. Low-level formatting -------------------- Seagate ATA Interface drives are low-level formatted at the factory and do not require additional low-level formatting before use. Note. If you are installing only a single drive in your computer, you can use the DOS program SETUP.EXE (supplied with MS-DOS 5.0 and above) to partition and format the drive. See your DOS manual for details. After you successfully run SETUP.EXE, your drive will be ready to use, and you can skip the partitioning and formatting steps below. Partitioning ------------ The partitioning process subdivides a single disc drive into partitions that behave as separate logical drives (labeled C, D, E, etc.). You can also set up the entire disc as a single partition. 1. Restart your computer. Boot up the computer using a diskette that contains DOS system files. 2. Run the FDISK program. Insert a DOS program diskette containing the FDISK program into your diskette drive. At the DOS prompt, type fdisk and press ENTER. Then follow the directions on the screen to create one or more partitions. See your DOS manual for details. If you are partitioning a drive that will be used to boot the computer, make sure that the primary partition is marked active. High-level formatting --------------------- High-level formatting verifies the information written by the low-level format and creates file allocation tables used to catalog and access files. Caution. Make sure that you know the correct drive letter for the partition you wish to format. Formatting a drive that contains data may destroy the data on that drive. 1. Run the FORMAT program. Insert a DOS program diskette containing the FORMAT program into your diskette drive. At the DOS prompt, type format, followed by the drive letter for the first drive partition you want to format (for example, format C:). Then, press ENTER. Repeat this procedure to format each of the new drive partitions you have created. Consult your DOS manual for FORMAT command options. Note. If you are formatting the drive partition that will be used to boot your computer (the "C" drive), copy the DOS system files to this drive. To do this, type /s after the format command (for example, format C: /s) 2. Verify the drive capacity. After high-level formatting a drive, you can verify the usable drive capacity by running the DOS CHKDSK utility program. Storing and shipping your drive ------------------------------- Keep your original box and packing materials for storing or shipping your drive. The box has a Seagate Approved Package label. Shipping a drive in an unapproved container voids the warranty. Call your authorized Seagate distributor to purchase additional boxes. ********************************************************************** G E N E R A L ********************************************************************** SEAGATE SUPPORT SERVICES Seagate Technology ------------------ Technical Support Services If you need assistance installing your drive, consult your dealer.
