Jumpers
TOSHIBA MK234FC/MK232FC PRODUCT SPECIFICATION 71Y101658
Jumper Setting
==============
There are 2 set of jumpers on the PCB, PJ10(12-pin) and PJ12(4-pin).
PJ10 is used for customer options and manufacture test. PJ12 is TBD.
Pin 1 to 8 of PJ10 is used for customer option and pin 9 to pin 12 is
used for manufacture test. User should not set jumpers in 9-10 and
11-12.

PJ10 1-2 LED
-------------
A jumper should be set across pins 1 and 2 to connect the active
Signal to the -HOST Slave/Active signal (PJ11-39) on the drive's
interface connector. This allows the use of an external LED. An
external current limiting resistor is required. See also PJ10-3/4
below. On a 2-drive system it is possible for each drive to be
connected to an LED.
PJ10 3-4 Slave Present
----------------------
A jumper should be set across pins 3 and 4 when using a system which
expects a slave drive to provide a SLAVE PRESENT signal. The jumper
connects the -HOST Slave/Active signal (PJ11-39) on the drive's
interface connector to system ground.
Note: This jumper pair (3-4) and jumpers 1-2 are mutally exclusive.
Both pairs should not be shorted simultaneously.
PJ10 5-6 Master/Slave
---------------------
If a jumper is set across pins 5 and 6, the drive is configured as a
Master drive, otherwise is configured as a Slave drive.
PJ10 7-8 Slave Drive Present
----------------------------
Setting a jumper across pins 7 and 8 indicates that a Slave drive is
present. In a 2-drive system, this must be set on the Master drive.
PJ10 9-12 Test
--------------
These pins are factory set and should not be changed.

In a two drive system, it is possible two drive LED with both drives.
(b)
If the disk drive is connected to some drive that requires that the
signal, -SLAVE DRIVE PRESENT be supplied from the slave drive via the
interface signal -HOST SLV/ACT, then this jumper must be installed.
If this jumper is installed, the LED jumper must not be installed
because the two jumpers are mutually exclusive.
Adapter Board Option
--------------------
An adapter board is prepared for connecting TASK FILE INTERFACE drive
(40 pin) to AT card slot.
PART NUMBER HDF3001ZZ01
CIRCUIT DIAGRAM 34M901215
Adapter Board Jumper Option
---------------------------
3 jumpers labeled PJ1 through PJ3 are provided on the adapter board.
The functions of the jumpers are described below.
PJ1 Install jumper to set the board to use SECONDARY address.
PJ2 Short pin 1-2 for the systems that do not read the STATUS
register to reset IRQ14. Normally short pin 2-3.
PJ3 Always open. Option for grounding pin 34 of the drive interface.
This is needed if the drive needs this pin to be grounded when
MASTER/SLAVE mode is used.

Mounting Instructions
---------------------
When mounting the drive, the cabinet frame should be spaced a minimum
of 0.1 inch (2.5 mm) from the outer surface of the HDA and PCB to
allow vibration to be absorbed by the drive vibration mounting.
The drive may be mounted using the 4 tapped holes located on the
side mounting frames or the 4 holes on the bottom frame of the drive.
Screws should not penetrate more than 0.1 inches (2.5 mm) from the
outer surface of drive frame in order to ensure adequate clearance
between screw tips and the PCB.
The drive frame is electrically isolated from the HDA (signal
ground).
Mounting screws M3X0.5 or 6-32UNC, four in bottom, two in each side.
Cooling
-------
Cabinet packaging designs must provide ample air circulation around
the drive to ensure environmental limits are not exceeded.
The temperature at the points indicated below should be less than
the values shown.
Outside surfaces of HDA 140*F (60*C)
Side frame 149*F (65*C)

Features
TOSHIBA MK-232FC/MK-234FC PRODUCT SPECIFICATION 71Y101658
General Description
-------------------
The MK230FC comprises a series of intelligent disk drives, herein-
after referred to as the MK230FC or simply as the drive.
The drive features an IBM PC-AT(R) embedded controller that requires
a simplified adapter board for interfacing to an AT or AT compatible
bus. Size and mounting details are identical to industry standard
3.5" mini floppy disk drives. All drives have high performance and
feature fast access times, a formatted recording capacity of up to
106 Megabytes and very high reliability. The drives employ Winchester
technology and a closed loop servo control system.
Installation Note for MK234FC
-----------------------------
General Information
The new MK234FC units delivered in November 89 has a translation
mode implemented. This could causes some problems by installation.
Following is a description how to install this drive by working with
the translation mode.
1. Setup
In a normal IBM BIOS table the drive parameter of the TOSHIBA
drive is not implemented. (845 cylinder, 7 heads, 35 sectors, 101
MB). Because of this purpose, user has to use a drive type by
using the setup program, which has more capacity as the TOSHIBA
drive.
EXAMPLE
Type 9: 900 cylinder, 15 heads, 17 sectors, 112 MB
2. Low Format
Low format run is not necessary, because in general the TOSHIBA
drive is pre formatted with an interleave of 1:1.
3. Fdisk
By using DOS 3.3 the drive has to be setup in partitions of
maximum size of 32MB. By using a drive type with higher capacity
as the TOSHIBA be careful not to overtake the maximum capacity of
the TOSHIBA drive (101 MB).
EXAMPLE
By using drive type 9, fdisk program shows following partition
size:
C : cylinder 0 to 256 (32 MB)
D : cylinder 257 to 513 (32 MB)
E : cylinder 514 to 770 (32 MB)
F : cylinder 771 to 899 (16 MB)
By using the complete size, which is shown by fdisk program, the
TOSHIBA maximum capacity would be overtaken. So the last
partition must be made smaller. This can be also done by the fdisk
program. By this example the maximum size for partition F has to
be 5 MB (40 cylinder):
F : cylinder 771 to 801 (5 MB)

Error Reporting
---------------
At the start of the execution of the command, the command register
is checked for condition which would lead to an aborted command. Then
the operation is attempted. Any subsequent error terminates the
command at the point that it is discovered. The errors that are valid
for each command are summarized below.

Format operation
----------------
MK230FC has ability to maintain defects by itself. The drive has own
information about the defects on the media and will handle defective
sectors by itself. MK230FC is shipped already formatted by the manu-
facturer assigning defects. So user should not format (Low level
format) the drive unless detected new defect (growing defect).
To assign the defective sector to spare location, the user should set
40H for the ID field data of FORMAT TRACK command. Then the drive
will alternate sector during format operation. It is not correct to
format the track when there is no growing defects. The drive may
alternate sector by its own defect information on the media. The
previously alternated sector will be alternated again and may fall in
to lack of alternate sectors.
Product Description
-------------------
The MK230FC consists of an HDA (Head Disk Assembly), a printed
circuit board and a steel frame. The HDA is a sealed module and
contains a disk spindle assembly, a head actuator assembly and an air
filtration system. Reliability is enhanced through the use of
Winchester technology. The actuator is a rotary voice coil motor and
provides high-speed access.
The disks are driven directly by a DC spindle motor. Air filtration
is provided by means of a high performance air filtration system
using both breather and circulation filters.
The drive provides a carriage lock mechanism which actuates auto-
matically on power down, thus preventing head/media damage during
non-operating or transportation conditions.
The printed circuit board is located externally to the HDA and
contains all the electronic circuitry necessary to operate the drive
except the head drivers. The board also holds the power supply and
interface signal connectors. Only the head control IC's are located
inside the HDA.
