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 ST9655 family drive for cable select, install both master/slave jumpers. ********************************************************************** I N S T A L L ********************************************************************** SEAGATE ST9655/9550/9385AG INSTALLATION GUIDE 36286-001, REV.A 10/94 Notes On Installation ===================== Mounting the drive ------------------ Mount the drive securely in the computer using M3X0.5 metric screws in the four bottom mounting holes or the four side mounting holes. You can mount the drive in any orientation. Be careful not to strain or crimp the interface/power cable. Caution To prevent damage to the drive: - Be careful not to bend the drive connector pins, especially when plugging the drive into a fixed connector. - Use mounting screws of the correct size and length. - Gently tighten the mounting screws_do not apply more than 3 inch-pounds of torque. - Do not insert mounting screws more than 0.15 inch. NOTE This drive meets industry-standard MCC mounting specifications. When installing this drive in a fixed-mounting application, you must use MCC-compatible connectors and mounting hardware. If the mounting holes in your computer do not line up with the mounting holes on the drive, your computer may not be MCC-compatible. Attaching cables ---------------- This drive is designed for a host computer that supplies interface signals and +5V power through a single 44-pin connector and cable. ********************************************************************** F E A T U R E S ********************************************************************** SEAGATE ST9655/9550/9385AG INSTALLATION GUIDE 36286-001, REV.A 10/94 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 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. The table below lists cylinder, head and sector information for the ST9655 family drives. +-----------------------+----------+----------+----------+ |Drive specification |ST9655AG |ST9550AG |ST9385AG | +-----------------------+----------+----------+----------+ |No. cylinders | 1,016 | 942 | 934 | +-----------------------+----------+----------+----------+ |No. read/write heads | 16 | 16 | 14 | +-----------------------+----------+----------+----------+ |No. sectors per track | 63 | 59 | 51 | +-----------------------+----------+----------+----------+ |Total no. sectors | 1,024,128| 889,248| 666,876 | +-----------------------+----------+----------+----------+ |Bytes per sector | 512 | 512 | 512 | +-----------------------+----------+----------+----------+ |Capacity (Mbytes) | | | | | BIOS calculated | 499 | 434 | 325 | | Usable | 524 | 455 | 341 | +-----------------------+----------+----------+----------+ Formatting and Partitioning the drive ------------------------------------- CAUTION Formatting or partitioning a drive that contains data destroys that data. Make sure all data has been safely backed up before re- partitioning or reformatting a drive that contains data. 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 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. 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. Compatibility Notes ------------------- The ST9655 family drives conform to the ATA interface specifications. The host system BIOS must provide support for the ATA interface command set. For a detailed description of the ATA commands implemented by these drives, see the Seagate ST9655 Family Product Manual and the Seagate ATA Interface Reference Manual. - In accordance with ATA specifications, the system BIOS must reset any emulation/translation parameters after a hard reset. - In some configurations, a ST9655 family drive may supply up to 16 bytes of error correction code (ECC) with the Read Long and Write Long commands. Depending on the drive type, your system BIOS may look for 4 bytes of ECC. If your system BIOS expects 4 bytes of ECC and the drive supplies a different number of bytes, some drive diagnostic programs may fail,typically resulting in timeout errors. Consult your computer documentation or call your computer dealer or manufacturer for information on configuring your computer to receive more than 4 bytes of ECC. - Some older drive diagnostic programs may incorrectly report an ECC detection failure when analyzing an ST9655 family drive. This occurs because the drive hardware corrects the data automatically, avoiding the error rather than reporting it. Such a report does not indicate a drive malfunction.
