INSTALLATION

Steps:

1. Turn off the computer and all attached peripheral equipment, such as printers and monitors.

2. Remove the screws attaching the computer’s cover, and remove the cover from the system.

3. Remove the drive from the ESD (Electro Static Discharge) bag, carefully placing the drive on your work surface.

4. Configure the disk drive jumpers as necessary. Refer to master/slave jumper table below for more details.

5. Connect the cables; align the colored striped edge of the interface cable to pin 1 of the drive interface connector.

6. Partially insert the drive into the drive bay. Select an unused power connector from the power supply and connect it to the drive. If there are no unused power connections on the power supply, you can purchase a “Y” cable adapter fr om your dealer. This connector will allow you to add another power connection for your new drive.

7. Now that the drives are jumpered, connected, and have power cables attached, secure the drive or the mounting frame with four 6-32x.25 screws.

CAUTION: Do not use screws of excess length when attaching the drive. Damage to the drive’s cir cuit board could result. The maximum insertion in

bottom holes is .25”, the maximum insertion for side holes is .125”.

8. All Seagate A TA disk drives are low level formatted at the factory.

It is only necessary to run SETUP, FDISK and DOS FORMAT.

9. AT BIOS (CMOS) setup ( refer to your system owners manual):

a) Many newer computers will automatically install your Seagate

disk drive. Insure that your Master/Slave (C/D) jumper is properly configured.

b) If the AT BIOS supports a user definable drive type, program the BIOS

to the parameters in the table below.

for all drives and the Landing Zone should be set to the number of cylinders

NOTE: Precomp should be set to zero (0)

c) If the AT BIOS does not support user definable drive type select a drive type that is

close to the drives parameters, but do not exceed the drives formatted capacity.

d) You may use the EZ-Drive® installation utility supplied with your Seagate disk drive

to do the configuration. Insert the EZ-Drive diskette into drive A:> and type EZ <ENTER> and it will automatically configure the drive.

10. The drive is now ready for partioning and high-level formatting with the operating system.

If you did not use EZ-Drive (EZ-Drive performs these functions), 1.) partition the drive first using the FDISK command from MS-DOS version 3.3 or higher and 2.) high-level format the drive using the FORMAT command from MS-DOS.
