Notes of Installation
=====================
Automatic Headpark and Lock Operation
-------------------------------------
Immediately following power-down, dynamic braking of the spinning
disks delays momentarily and lets the heads move to an inner
mechanical stop. A small fixed magnet holds the heads in place as the
disk spin down. The heads are released only when power is again
applied.
Dual Drive Support
------------------
Two drives may be accessed via a common interface cable, using the
same range of I/O addresses. A jumper on J20 designates the drive as
a master. When J20 is not jumpered, the drive is a slave. Whether a
drive is a master or slave determines the function of pin 28, DASP-,
for that drive. DASP- (Drive Active Slave Present) is a time-multi-
plexed signal that serves as an input on the master and an output on
the slave. At power on, the master allows a time period for the slave
to set the DASP- line. If the slave fails to do so, the master
assumes it is the only drive in the system. After DASP- has been set,
or after the master's input period has expired, the DASP- line is
used as a drive active line and is set when the host accesses either
drive.
All Task File registers are written in parallel to both drives. The
interface processor on each drive decides whether a command written
to it should be executed; this depends on the type of command and
which drive is selected. Only the drive selected executes the command
and activates the data bus in response to host I/O reads; the drive
not selected remains inactive.
A master/slave relationship exists between the two drives: drive 0 is
the master, and drive 1, the slave. In response to the Execute
Diagnostics command, both drives execute diagnostics. The slave re-
ports its status with its own, and then reports to the host.
Drive Type
----------
7000 Series drives incorporate a dynamic configuration algorithm.
Within limits of the drive's capacity, the algorithm lets the host
configure CMOS to any DOS Legal ATA translation.
Cooling
-------
The cabinet cooling must be designed by the customer so that the
ambient temperatures measured 0,5" above the PCBA and top cover
surfaces do not exceed temperature specifications listed in this
describtion.
Power Connector
---------------
Power is applied through J2, a 4-pin connector (Molex P/N 1-480424-0;
AMP P/N 1-480424-0).
Never force poloarited connectors into place.

Introduction
------------
Maxtor 7000 Series AT disk drives are 1" high, 3.5" random access
storage devices which incorporate an on-board AT controller. Maxtor
engineers have applied recent advances in hard drive technology to
the design and manufacture of these drives. Reduced size and in-
creased durability make them especially well-suited to notebook,
laptop, and desktop applications.
Defect and Error Management
---------------------------
7000 Series drives employ a "push-down" defect management routine.
The drive organizes physical sectors into a logical string. If a
defective sector is found, it is skipped, and the entire logical
string is shifted down by one. Reserved sectors beyond the end of the
logical string prevent any loss of capacity or performance.
Any defective sectors are recorded while the drive is still at the
factory and the resulting list loads into SRAM during power on.
In the event of a data error, Error Correction Code (ECC) allow data
recovery even when several bits of the original data have been lost.
SRAM Buffer
-----------
The 3 major areas of SRAM (Static Random Access Memory) include:
defect management, a read buffer, and a write buffer.
Drive defects load into SRAM from the reserved history cylinder and
are referenced for every read, write, and seek operation. Each defect
causes all remaining logical data sectors to be shifted down by one.
Since the defect list is in SRAM, the drive can quickly determine the
logical offset to locate a desired sector.
The large read buffer and smaller write buffer optimize data through-
put for both fast and slow host systems.
Data Reliability
----------------
Reliability specifications require a proper implementation of the
host/drive interface, including correct interface timings, power
supply voltages, environmentsl conditions, and data handling circuits
in the host system. General error rate computations exclude any
errors caused by factory-located defects or host system failures.
Specified error rates are based on the assumptions that
1. the drive operates within DC power requirements, and
2. any errors caused by media defects or host system failures are
excluded from error rate computations.

Basic Installation Steps
------------------------
Install a 40-pin ribbon cable connector. The striped edge of this
cable represents pin 1 and must be oriented towards pin 1 at the
drive connector and at the host connector.
Install a DC power connector.
Secure the drive in a drive bay with 6-32 x 1/4" screws.
If the AT BIOS supports a user-programmable drive type, select and
programm the drive parameters that will give the highest available
capacity.
If the AT VIOS does not supports user-programmable drive types,
choose one of the drive's translation paaarameters that matches a
standard drive type in BIOS.
The drive is now ready for partioning and high-level formatting with
any operating system.

MAXTOR IDE INSTALLATION
INSTALLATION PROCEDURE FOR AN IDE DRIVE
---------------------------------------
1. Install a 40 pin Data Cable ensuring that pin 1, which can be
identified by the striped edge of the cable, is closest to the
power connector on the drive.
2. Install a DC power cable to the back of the drive.
3. Verify the jumper configurations for Master/Slave operation
(Note: Master will be the bootable drive. The slave will not
be bootable.) Also make sure the existing C: drive is jumped
to be the Master in a two drive system, not the only drive in
the system.
4. Apply power to the computer.
4a. When memory test is complete go into your system's Standard
CMOS set-up.
(Note: There are various ways to get into CMOS set-up, please
refer to system's manual for instructions.)
4b. If your system's BIOS supports a user programmable drive
type, program the BIOS with the default parameters of your
drive. If your system does not support a user programmable
drive type choose parameters that closely match but do not
exceed the drives MegaByte capacity. Escape from set-up
then choose write to CMOS and exit.
5. Boot from a DOS diskette that has FDISK.EXE and FORMAT.COM on
it. At the A> prompt type in FDISK. At the menu options select
option 1 to create a DOS partition. Another menu will appear
and from those options choose 1 to create a Primary DOS
partition. Select yes to make 1 large partition and it will
automatically become active. Then escape from FDISK.
6. At the A> prompt type in FORMAT C:/S This does a high-level
format on the drive and transfers the system files in order for
the drive to be bootable. (Note: IDE drives are low-level
formatted from the manufacturer and only need a high-level
format).
To configure the drive as a slave drive repeat steps 1-4 and
proceed with steps 5a. and 6a. as follows:
5a. At the C> prompt type in FDISK. When the menu options appear
select option 5 to switch to the second drive. Enter fixed
disk drive number 2. Then choose option 1 to create a DOS
partition, then select option 1 again to create a Primary DOS
partition or option 2 to create an Extended DOS partition.
(Note: C and D drives will always be the Primary partitions
but only the Primary partition on C: will have a status of
active).
6a. Proceed with a high-level format on the drive by typing FORMAT
D: (Note: Make sure the correct drive letter has been selected
for format).
7. The drive is now bootable. As a test remove the DOS diskette
from A and press reset to reboot the computer, a C> should be
displayed, the drive is now ready for operation.
