Installation 3.3 HARDWARE OPTIONS 3.3.1 ATA Interface Connector The configuration of a Maxtor DiamondMax Plus9 60/80/120/160/ 200GB AT hard disk drive depends on the host system in which it is to be installed. This section describes the hardware options that you must take into account prior to installation.
Installation The configuration of the following three jumpers controls the drive’s five modes of operation: • CS – Cable Select • DS – Drive Select • CLJ– Cylinder Limitation Jumper The AT PCB has two jumper locations provided to configure the drive in a system. The default configuration for the drive as shipped from the factory is with a jumper across the CS location, and open positions in the DS and CLJ positions.
Installation Once you install the CS jumper, the drive is configured as a Master or Slave by the state of the Cable Select signal: pin 28 of the ATA bus connector. Please note that pin 28 is a vendor-specific pin that Maxtor is using for a specific purpose. More than one function is allocated to CS, according to the ATA CAM specification (see reference to this specification in Chapter 1). If pin 28 is a 0 (grounded), the drive is configured as a Master.
Installation 3.3.1.4 Cylinder Limitation Jumper (CLJ) For user capacities below 66,055,248 sectors (32GB), inserting the CLJ jumper limits the Number of Cylinders field 1 to a value of 16,383, as reported in IDENTIFY DEVICE data word. This allows software drivers to determine that the actual capacity is larger than indicated by the maximum CHS, requiring LBA addressing to use the full capacity.
Installation 3.3.2 ATA BUS ADAPTER There are two ways you can configure a system to allow the Maxtor DiamondMax Plus9 hard disk drives to communicate over the ATA bus of an IBM or IBM-compatible PC: 1. Connect the drive to a 40-pin ATA bus connector (if available) on the motherboard of the PC. 2. Install an IDE-compatible adapter board in the PC, and connect the drive to the adapter board. This board is available at Maxtor (p/n: K01PCAT133. 3.3.2.

Installation 3.4.4 SATA (Serial ATA) Interface Connector The Maxtor DiamondMax Plus9 60/80/120/160/200GB AT hard disk drives also offer an optional Serial ATA interface. SATA has no user changeable configuration jumpers. All configurations are controlled in the SATA interface by the host. Figure 3-7 The SATA Interface Connector 3.4.
Installation 3.4.5.1 SATA Bus Connector Some PC motherboards have a built in SATA bus connector. These SATA bus connectors are compatible with Maxtor DiamondMax Plus9 hard disk drives.If the motherboard has a SATA connector, simply connect a 7 pin SATA cable between the drive and the motherboard. 3.4.5.

Installation 3.7 TECHNIQUES IN DRIVE CONFIGURATION 3.7.1 The 528-Megabytes Barrier Older BIOS that only support Int 13 commands for accessing ATA drives through DOS based operating systems will be limited to use only 1024 cylinders. This will reduce the effective capacity of the drive to 528Mbytes. Whenever possible the Maxtor DiamondMax Plus9 60/80/120/160/ 200GB AT drive should be used on systems that support LBA translation to ensure the use of the entire capacity of the disk drive.
Installation that can be used to overcome this barrier: • Use a third party software that supplements the BIOS and adds Int 13 extension support. • Obtain a BIOS upgrade from the system board manufacturer. Many system board manufacturers allow their BIOS to be upgraded in the field using special download utilities. Information on BIOS upgrades can be obtained on the System Board Customer Service respective web sites on the Internet. • Insert the Cylinder Limitation Jumper (CLJ) on the drive (see Section 3.
Installation During the AT system CMOS setup, you must enter the drive type for the Maxtor DiamondMax Plus9 hard disk drives. The drive supports the translation of its physical drive geometry parameters such as cylinders, heads, and sectors per track to a logical addressing mode. The drive can work with different BIOS drive-type tables of the various host systems. You can choose any drive type that does not exceed the capacity of the drive.

Appendix A BREAKING THE 137 GIGABYTE STORAGE BARRIER This appendix provides information about the 137GB storage barrier. It discusses the history, cause and the solution to overcome this barrier. A.1 Breaking the 137 Gigabyte Storage Barrier Capacity barriers have been a fact of the personal computer world since its beginnings in the early 1980’s. At least 10 different capacity barriers have occurred in the storage industry over the last 15 years.
Breaking the 137GB Storage Barrier device storage capacity by the people who designed hard disk structures, access routines, and operating systems many years ago. They thought, “Who will ever have xxx much storage?” In some cases, the barriers were caused by hardware or software bugs not found until hard disks had grown in size beyond a certain point where the bugs would occur.
Breaking the 137GB Storage Barrier A.1.2 Solving the 137 Gigabyte Capacity Barrier As described earlier, the issue causing the 137-gigabyte barrier is the 28bit addressing method of the original ATA specification. A change to expand this method was required to provide more address bits for the interface, allowing significant growth for many years to come. A critical issue in expanding the addressing capability was maintaining compatibility with the existing installed base of products.
Breaking the 137GB Storage Barrier A.1.5 What Else is Involved? Effort is required from OS vendors to increase storage device addressing up to 48 bits or more. This increase will be a significant challenge for many OS vendors that have 32-bit code models. Adapting to 48-bit commands will be easy, but most vendors will stop filling data at the 32bit boundary and pad the upper 16 bits with zeros, leaving that space empty.
Breaking the 137GB Storage Barrier a little more than 30 pages of text • 33 megabytes = 33,000,000 bytes more than 8,000 pages of text or 25 300-page books • 137 gigabytes = 137,000,000,000 bytes more than 100,000 books, or the contents of a good library • 2.2 terabytes = 2,200,000,000,000 bytes almost 2,000,000 books, or the about content of the Library of Congress • 144 petabytes = 144,000,000,000,000,000 bytes 120 billion books – (more than all that man has written) • 9.
GLOSSARY A ACCESS – (v) Read, write, or update information on some storage medium, such as a disk. (n) One of these operations. ACCESS TIME – The interval between the time a request for data is made by the system and the time the data is available from the drive. Access time includes the actual seek time, rotational latency, and command processing overhead time. See also seek, rotational latency, and overhead.
Glossary BPI – Abbreviation for bits per inch. A measure of how densely information is packed on a storage medium. Flux changes per inch is also a term commonly used in describing storage density on a magnetic surface. BUFFER – An area of RAM reserved for temporary storage of data that is waiting to be sent to a device that is not yet ready to receive it. The data is usually on its way to or from the disk drive or some other peripheral device.
Glossary DISK CONTROLLER – A plug-in board, or embedded circuitry on the drive, that passes information to and from the disk. The Maxtor disk drives all have controllers embedded on the drive printed-circuit board. DISKWARE – The program instructions and data stored on the disk for use by a processor. DMA – Acronym for direct memory access.
Glossary I GIGABYTE (GB) – One billion bytes (one thousand megabytes). GUIDE RAILS – Plastic strips attached to the sides of a disk drive mounted in an IBM AT and compatible computers so that the drive easily slides into place. H HALF HEIGHT – Term used to describe a drive that occupies half the vertical space of the original full size 5 1/4-inch drive. 1.625 inches high.
Glossary K M KILOBYTE (Kb) – A unit of measure consisting of 1,024 (210) bytes. MB – See megabyte. L LANDING ZONE – A position inside the disk’s inner cylinder in a non data area reserved as a place to rest the heads during the time that power is off. Using this area prevents the heads from touching the surface in data areas upon power down, adding to the data integrity and reliability of the disk drive.
Glossary MTTR – Mean Time To Repair. The average time it takes to repair a drive that has failed for some reason. This only takes into consideration the changing of the major sub-assemblies such as circuit board or sealed housing. Component level repair is not included in this number as this type of repair is not performed in the field. O OVERHEAD – The processing time of a command by the controller, host adapter or drive prior to any actual disk accesses taking place.
Glossary REMOVABLE DISK – Generally said of disk drives where the disk itself is meant to be removed, and in particular of hard disks using disks mounted in cartridges. Their advantage is that multiple disks can be used to increase the amount of stored material, and that once removed, the disk can be stored away to prevent unauthorized use. RLL – Run Length Limited. A method used on some hard disks to encode data into magnetic pulses.
Glossary SUBSTRATE – The material the disk platter is made of beneath the magnetic coating. Hard disks are generally made of aluminum or magnesium alloy (or glass, for optical disks) while the substrate of floppies is usually mylar. SURFACE – The top or bottom side of the platter which is coated with the magnetic material for recording data. On some drives one surface may be reserved for positioning information. U UNFORMATTED CAPACITY – The total number of bytes of data that could be fit onto a disk.
