 Since each design installation of the product can be unique. The
 disk drive can be mounted in any of the major axes.


 Physical Mounting
 -----------------
 Typically, the disk drive is fastened directly to a chassis with four
 6-32 screws. There are twelve (12) threaded mounting holes (for 6-32
 screws) on the disk drive: four on each side, and four on the bottom.
 Use the following guidelines to mount the disk drive:

 - Use 6-32 screws and torque them to 10 inch-pounds.

 - When mounted, the hardware must not protrude more than 3 mm (0.12
   inch) beyond the inside of the disk drive frame.


 ATA Interface Bus Connector
 ---------------------------
 An unshielded 40-pin bus connector is located on the rear of drive
 electronics/controller PCA. The physical construction and pin
 assignment for this connector conform to the ATA specification.


 DC Power Connector
 ------------------
 The power connector on the rear of drive electronics/controller PCA
 provides connection for dc power used by the drive.


 Mating Connector and Cabling Requirements
 -----------------------------------------
 The nonshielded ATA cable connector should be a 40-conductor
 connector consisting of two rows of 20 female contacts with adjacent
 contacts 2.54 mm (0.1 inch) apart. Keyed connectors should be used.

 The disk drive adheres to the cabling requirements and limitations
 set forth in the ATA specifications.


 Front Panel Activity Indicator
 ------------------------------
 The optional light emitting diode (LED) on the front of the disk
 drive is an activity light that indicates the status of the DASP(L)
 (Drive Active/Drive 1 Present) line on the ATA bus.

     Dupont 77138-101; for AWG 32-36 wire, use Dupont 77139-101).


 Buffer Management
 -----------------
 This product incorporates a 64-kilobyte buffer for the Look-Ahead
 Read Cache function. Upon receiving a READ command, the controller
 will load the data plus as much additional data as possible into the
 buffer. The data from any of these sectors can be read independently
 by future READ commands without accessing the media.

 Product Description
 -------------------
 The HP C2230 Series, Option 060, Disk Drives are reliable, high
 capacity, high performance, random access mass storage devices
 utilizing sputtered thin-film 3.5-inch disks as storage media. These
 drives incorporate a hybrid servo design that provides the
 flexibility and performance of a dedicated servo system and the
 dynamic head alignment of an embedded servo system.

 The electrical interface compatible with the proposed Common Access
 Method (CAM) AT Bus Attachment (ATA), also known as the IDE
 (Intelligent Drive Electronics) Interface.

 Key features of the HP 2230 Series, Option 060 Disk Drives include:

 - High reliability (150,000 hours MTBF)

 - Multiple zone recording

 - Look-Ahead Read Caching

 - Orderable Options:
     Front bezel
     Front panel LED (color can be specified)

 For customer needs that differ from the products described in this
 manual, Hewlett-Packard can provide specially modified products.
 These modifications are ordered, defined, engineered, and
 manufactured under "special" contract negotiations.

       +----------------------------------+--------+


 Error Correction Code
 ---------------------
 The HP C2230 Option 060 disk drives use a computer generated error
 correction code (ECC) for detection and correction of data errors.
 During a Write operation, the ECC function generates 7 bytes of ECC
 information, and writes it into the ECC field as the sector is
 written. During a Read operation, the ECC function uses this
 information to detect any errors and to correct the data.

 The ECC function can correct a maximum of 11 bits in a single burst
 error.


 Drive Type Configuration Details
 --------------------------------
 The capacities provide the maximum number of logical sectors
 available from the C2230 Series, Option 060 disk drives.

 The actual number of usable sectors available to the host system is
 determined by the "Drive Type" parameters selected when the drive is
 installed and configured.

 The ROM BIOS in most of the DOS systems available today can address
 the following maximum Drive Type parameters:

 - Cylinders:     1024; logical addresses 0 (zero) to 1023
 - Heads:           16; logical addresses 0 (zero) to 15
 - Sectors/Track:   63; logical addresses 1 (one) to 63

 The C2230 Series, Option 060 disk drives contain more than the
 maximum number of DOS-addressable cylinders and sectors per track,
 and less than the maximum number of DOS-addessable data heads. In
 order to compensate for these differences and provide the maximum
 available disk storage area to the host, the drive firmware performs
 a "logical translation" or "mapping" from the Drive Type parameters
 selected during the head drive setup to the addressing structure of
 the disk drive.


 Execute Drive Diagnostic
 ------------------------
 Perform the internal diagnostic tests implemented by the drive. The
 DRV bit is ignored. Both drives, if present execute this command.

 If Drive 1 is present:
 - Both drives execute diagnostics
 - Drive 0 waits up to 15 seconds for Drive 1 to assert PDIAG(-)
 - If Drive 1 has not asserted PDIAG(-), indicating a failure, Drive 0
   shall sppend 80h to its own diagnostic status
 - Drive 0 clears BSY, and generates an interrupt
 - If Drive 1 diagnostic failure is detected when Drive 0 status is
   read, Drive 1 status is obtained by setting the DRV bit, and
   reading status.

 If Drive 1 is not present:
 - Drive 0 executes its diagnostics
 - Drive 0 posts only its own diagnostic results
 - Drive 0 clears BSY, and generates an interrupt

 The Diagnostic Code reported in the Error Register is a unique 8 bit
 code:

         05             Controller microprocessor error
         8x             Drive 1 failed


 RAM Buffer
 ----------
 The RAM Buffer contains 64-kilobytes of static RAM. All data
 transferred between the host and the disk must pass through the RAM
 buffer.
