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

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

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 

 

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.

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)".

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.

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: There are two different revisions of the ST280A 

        1. If you have a 94204-xxC, then you can connect two different 

         model drives on the same host adapter. (i.e. a 94204-xxC and 

         a 94354-xxx drive) 

 

        2. If you do not have a "C" after the model number, then you 

         can only connect two similar Wren 2 94204-xx model drives.

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)".

J5 Jumper  Funtion Description (* indicates default) 

DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD 

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). 

 

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. 

 

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). 

 

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. 

 

ON         Cable select option enabled.  Jumper E must also be 

           installed to enable cable select. 

 

OFF        Cable select option not enabled. 

 

ON         Optional feature #1 enabled 

OFF        Optional feature #1 not enabled 

 

ON         Spindle synch reference signal is on I/O connector J1 pin 39. 

OFF        Spindle synch reference signal is not on J1 pin 39. 

 

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. 

 

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).

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

65535 or -1, which are functionally equivalent to "none (not used)".

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)".

 * MAY REQUIRE FORMATTING AND PARTITIONING SOFTWARE.  ALSO, CHECK TO 

SEE IF YOUR CMOS SETUP HAS A "CUSTOM" OR "USER DEFINABLE" DRIVE TYPE 

AVAILABLE. (see below) 

 

Possible translation:   985 cyl, 13 heads, 32 sectors = 209,797,120 

 

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.
