Jumper Setting
==============
Drive Configuration - Drive 0/Drive 1 Selection
-----------------------------------------------
When the drive is connected to a 68 pin ATA interface, up to two
drives may be daisy chained on the Host bus. The designation of Drive
0 or Drive 1 can be made using the Cable Select Option (CSEL).
CSEL Pin 56
+------------------+------------------+

| HOST | | Drive 0 | | Drive 1 |
+----+----+ +----+----+ +----+----+
Optional LED | |
| |-DASP Pin 62 |
+------------------+------------------+
By selectively grounding the input signal CSEL the system
manufacturer can select which drive will recognise itself as Drive 0.
Linking -DASP (Pin 62) between Drive 0 and 1 will allow Drive 0 to
recognise that drive 1 is present. -DASP may optionally be connected
to an activity LED for the Host system.
LED connection
--------------
When a LED is connected on the 68 pin ATA interface (pin 62), an
external current limiting resistor is required to be placed in series
between pin 62 and the 5V supply. The value of this resistor is
dependent on the LED used and is typically 130 Ohms.

Look Ahead Cache
----------------
The drive has a 32K sector buffer of which, 28K is available to
buffer data between the disk and host. At the end of each READ
command, the drive will continue to read data into the sector buffer
until:-
1. the sector buffer is full or
2. a new command other than READ command is received.
If, during this "look ahead" the drive receives a READ command and
the requested start block is equal to the start block of the look
ahead (i.e. continuation of a sequential read) all available blocks
will be transferred directly from the cache buffer. If more blocks
are required to complete the transfer the drive will continue to read
from disk and the read operation will continue. There will be no
rotational latency incurred. At the end of the command, a new look
ahead sequence will be initiated.
If, during this "look ahead" the drive receives a READ command and
the requested start block is not equal to the start block of the look
ahead the look ahead will be terminated. The valid blocks currently
held in cache will then be examined and if the requested start block
has already been read into the cache then all available data will be
transferred directly from the cache buffer. If more blocks are re-
quired to complete the transfer the drive will continue to read from
disk and the read operation will continue as before else the cache
pointers will be reset and a new command will be started.

Introduction
------------
The CT80MC miniature hard disk drive offers a formatted data storage
capacity of 85.06 Mbytes and is designed to operate on the 68 pin ATA
and PC CARD-ATA interfaces. The drive is designed with a 10.5mm
height for compatibility with a PCMCIA Type III card slot. The drive
and controller electronics use WLSI and surface mount technology to
allow integration within the 1.8 inch form factor.
General
-------
The CT80MC hard disk drive is a random access data storage device
which uses two 48mm magnetic disks to provide a formatted capacity
of 85.06MB. The drive has a fixed physical format of 512 bytes per
sector, with up to 44 sectors per track.

Magnetic Field
--------------
There shall be no source of constant magnetic field which results
more than 0.0005 Tesla measured in the location occupied by the
magnetic heads when the drive is installed.
Defect Handling
---------------
A sector skipping technique is used where the logical address of the
defective sector and all subsequent sectors are advanced by one
sector. This skipping effect continues until a further defect is
encountered or the logical end is reached and spare sectors are used
to complete the specified disk capacity.
When shipped and after a LOW LEVEL DISK FORMAT has been performed all
defects will be skipped.
A number of sectors are reserved for the purpose of mapping out disk
defects. All disk defects found during manufacturing are stored in a
Manufacturing Defect List. This list is maintained by the drive and
store on reserved sectors on the disk.
