Hi,
As an owner of a Seagate Drive I had my own problems setting up
my drive. Ussually most problems are are related with setting up
correctly the drive to work on a pc. Here is some info on most
Seagate HD models, that (I think) will help other Seagate owners..
This info was taken from Seagate's BBS...
I hope this doc helps

Note: A "custom" or "user-definded" CMOS drivetype may ask for a
numerical value for the Write Precompensation cylinder and for the
Landing Zone cylinder. A basic rule-of-thumb for drive models that do
not require the old Write Precomp technique or a Landing Zone because
they are Auto-Parking is to add 1 to the cylinder value being used. As
an example: If cylinders equaled 820, then both Write Precomp and
Landing Zone would be entered as 821. Some BIOS will convert this to
65535 or -1, which are functionally equivalent to "none (not used)".

of the synchronized spindle reference signal (pin-1) and ground

terminated without an external resistor. It is also available on J4
pin-28 if the factory jumper is installed. The drive will
self-determine if it is a master of slave for spindle synchronization.
B HOST SLV/ACT: When this shunt is installed, -SLAVE PRESENT
(provided by the output of a 74HCT14) is applied to J4 pin-39 for
systems that require this signal from the Master drive. If jumper "B"
is installed, then jumper "E" must not be installed.
C MASTER: When this shunt is installed, the drive is configured
as the Master. When not installed, the drive is a Slave.
D SLAVE PRESENT: When installed, this shunt indicates to the
Master drive that a Slave is present. This shunt must be installed on
the Master drive in a two-drive system.
E ACTIVE: When this shunt is installed, DASP- is made present on
J4 pin-39. If "E" is installed, then "B" must not be installed.

JUMPER | FUNCTION:
A REFSIG: This location provides a port for external connection
of the synchronized spindle reference signal (pin-1) and ground
(pin-2). The reference signal is bi-directional, single-ended, and
terminated without an external resistor. It is also available on J4
pin-28 if the factory jumper is installed. The drive will
self-determine if it is a master of slave for spindle synchronization.
B HOST SLV/ACT: When this shunt is installed, -SLAVE PRESENT
(provided by the output of a 74HCT14) is applied to J4 pin-39 for
systems that require this signal from the Master drive. If jumper "B"
is installed, then jumper "E" must not be installed.
C MASTER: When this shunt is installed, the drive is configured
as the Master. When not installed, the drive is a Slave.
D SLAVE PRESENT: When installed, this shunt indicates to the
Master drive that a Slave is present. This shunt must be installed on
the Master drive in a two-drive system.
E ACTIVE: When this shunt is installed, DASP- is made present on
J4 pin-39. If "E" is installed, then "B" must not be installed.

Note: A "custom" or "user-definded" CMOS drivetype may ask for a
numerical value for the Write Precompensation cylinder and for the
Landing Zone cylinder. A basic rule-of-thumb for drive models that do
not require the old Write Precomp technique or a Landing Zone because
they are Auto-Parking is to add 1 to the cylinder value being used. As
an example: If cylinders equaled 820, then both Write Precomp and
Landing Zone would be entered as 821. Some BIOS will convert this to
65535 or -1, which are functionally equivalent to "none (not used)".
PHYSICAL/LOGICAL equivalent to NATIVE/TRANSLATION
WARNING - Already low-level formatted at the factory
Since a User-definable or Custom translation geometry may be used, it
is imperative that the values be written down and kept with your
permanent records for retrieval in the event of CMOS battery failure.

not require the old Write Precomp technique or a Landing Zone because
they are Auto-Parking is to add 1 to the cylinder value being used. As
an example: If cylinders equaled 820, then both Write Precomp and
Landing Zone would be entered as 821. Some BIOS will convert this to
65535 or -1, which are functionally equivalent to "none (not used)".

installed on either Bus Reset Hi or Bus Reset Low; the
drive will not function if neither set of pins is
jumpered.
(2) HSP/Assert "/DASP" signal: pin 39 on 40-pin AT/AT

an example: If cylinders equaled 820, then both Write Precomp and

A B
OFF OFF Drive is the slave (Drive 1).
OFF ON Drive is the master (Drive 0) with slave (Drive 1) present.
ON* OFF Drive is the master (Drive 0).
C
ON* DASP- is brought into drive through I/O pin 39
OFF DASP- is not used and is not connected to drive. I/O cable
pin 39 may be used for spindle synch if jumper H is
installed.
D
ON* No spindle synch reference is used. See also J6 position
R, which duplicates the function of this jumper. Either J5
D or J6 R may be jumpered to signify no synch spindle
reference is used.
OFF Spindle synch reference signal cable may be plugged onto
this jumper, J6 R or spinle synch ref may be taken from I/O
cable pin 28 (if jumper J installed) or pin 39 (if jumper H
installed).
E
ON I/O connector J1 pin 28 is used for Cable Select function.
Jumper F must also be installed to implement cable select.
OFF J1 pin 28 not used for Cable Select function.
F
ON Cable select option enabled. Jumper E must also be
installed to enable cable select.
OFF Cable select option not enabled.
G
ON Optional feature #1 enabled
OFF Optional feature #1 not enabled
H
ON Spindle synch reference signal is on I/O connector J1 pin 39.
OFF Spindle synch reference signal is not on J1 pin 39.
J
ON Spindle synch reference signal is on I/O connector J1 pin 28.
OFF Spindle synch reference signal is not on J1 pin 28.
J6 Jumper Funtion Description (2x2 jumper block)
-------------------------------------------------
L Remote LED cable connection (Not a jumper position). Do not
install a jumper if remote LED cable is not plugged here.
R
ON No spindle synch reference is used. See also J5 posistion
D, which duplicates the function of this jumper position.
Either J5D or J6 R may be used to signify no spindle synch
reference is used.
OFF Spindle sync reference signal cable may be plugged into
this jumper position, J5 D or the spindle synch reference
may be taken from I/O cable pin 28 (if jumper J installed)
or pin 39 (if jumper H installed).

Note: A "custom" or "user-definded" CMOS drivetype may ask for a
numerical value for the Write Precompensation cylinder and for the
Landing Zone cylinder. A basic rule-of-thumb for drive models that do
not require the old Write Precomp technique or a Landing Zone because
they are Auto-Parking is to add 1 to the cylinder value being used. As
an example: If cylinders equaled 820, then both Write Precomp and
Landing Zone would be entered as 821. Some BIOS will convert this to
65535 or -1, which are functionally equivalent to "none (not used)".
PHYSICAL/LOGICAL equivalent to NATIVE/TRANSLATION

Since a User-definable or Custom translation geometry may be used, it

Possible translation: 873 cyl, 16 heads, 24 sectors = 171,638,784
Note: A "custom" or "user-definded" CMOS drivetype may ask for a
numerical value for the Write Precompensation cylinder and for the
Landing Zone cylinder. A basic rule-of-thumb for drive models that do
not require the old Write Precomp technique or a Landing Zone because
they are Auto-Parking is to add 1 to the cylinder value being used. As
an example: If cylinders equaled 820, then both Write Precomp and
Landing Zone would be entered as 821. Some BIOS will convert this to
65535 or -1, which are functionally equivalent to "none (not used)".
PHYSICAL/LOGICAL equivalent to NATIVE/TRANSLATION
ZBR = Zone Bit Recording = Variable sectors per track
Already low-level formatted at the factory.
Since a User-definable or Custom translation geometry may be used, it
is imperative that the values be written down and kept with your
permanent records for retrieval in the event of CMOS battery failure.
