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.

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.

Features

HEWLETT HP C2230 OPTION 060 PRODUCT DESCRIPTION MANUAL P/N 5960-0875

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:

      Diagnostic Codes

     Diagnostic Code    Code
        (hex)           Description
         01             No error detected
         02             Formatter device error
         03             Sector buffer error
         04             ECC circuitry error
         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.
