Read before you begin...
Application. Your Seagate® drive is designed for IBM AT and compatible personal computers. It uses the ATA interface.
Warning. Turn off the computer before you open the case, touch any internal components or install the drive.
Static discharge. Observe these precautions to avoid static electricity, which can damage a drive or computer. Static electricity can be generated by wool or synthetic clothing, carpets and plastics of any kind including most bags.
∙Keep the drive in its static-shielded bag until you are ready to install it. Do not attach any cables to the drive while it is in its static-shielded bag.
∙Before you handle the drive, put on a grounded wrist strap, or ground yourself frequently by touching the metal chassis of a computer that is plugged into a grounded outlet. Wear a grounded wrist strap throughout the installation procedure.
∙Handle the drive gently and only by its edges or frame. Until you are ready to install it, place it only on an antistatic surface.
∙Do not touch the drive’s connector pins or its printed circuit board.
Drive handling. The drive is extremely fragile—handle it with care. Do not attach labels to any part of the drive.
Inspection. After you are familiar with the handling precautions listed above, inspect the drive. If it appears to be damaged, call your distributor or dealer immediately.
Warranty. See your authorized Seagate distributor or dealer.
Maintenance and repair. Seagate drives do not require maintenance. The head/disc assembly is sealed; a broken seal voids the warranty. Seagate customer service centers are the only facilities authorized to repair Seagate drives. Seagate does not sanction any third-party repair facilities.

Configuring the drive
1.Turn the computer off.
2.Remove your computer’s cover.
Caution. Special training or tools may be needed to service laptop computers. Removing the cover may void your warranty. Review the terms and conditions of your warranty before removing the cover.
3.Ground yourself. Wear a grounded wrist strap throughout this procedure, or frequently touch the metal chassis of a computer that is plugged into a grounded outlet.
4.Remove the drive from its antistatic bag.
5.Install master/slave jumpers. The master/slave jumper block, shown in Figure 1 on page 4, accepts 2-mm connectors and jumpers. Use Seagate part number 13211-001 or equivalent.
One-drive system: Configure the drive for a one-drive system as shown in Figure 1.
Two-drive system: With two ATA interface drives, you must designate one drive as the master, or drive 0, and the other drive as the slave, or drive 1. This can be done in either of two ways:
∙When using a standard ATA interface cable (that is, you are not using cable select): configure the drive as a master or a slave using the options jumper block as shown in Figure 1 on page 4.
∙When using cable select (that is, you have a special cable supporting this drive selection method, and your computer and both drives all support cable select): first install a jumper on pins 3-4 of the options jumper block as shown in Figure 1; then use a drive-select cable as described in step 5 of “Attaching cables” on page 3 to designate master and slave drives.

Attaching cables
Refer to Figure 1 on page 4 for the locations of the connectors.
1.Make sure the computer is off.
2.Put on a grounded wrist strap.
3.Connect the remote LED (optional).
4.Attach the power cable. Attach one of the computer power cables from the power supply of your computer to the 4-pin power connector on the drive.
5.Attach the interface cable. (Interface ribbon cable length must be 18 inches or less.)
Caution. Connector misalignment can damage the computer and the drive. Ribbon cables are delicate—be careful not to crimp or strain them.
One-drive system using a standard ATA 40-pin interface cable:
Connect one end of the cable to the computer’s host adapter card or to the hard drive connector located on the motherboard; connect the other end to the 40-pin interface connector. Align pin 1 on each cable connector with pin 1 on its matching equipment connector. (Cable lead 1 going to connector pin 1 is often denoted by a colored edge-stripe on the cable; the stripe will lie adjacent to the 4-pin power connector.)
Two-drive system with a standard ATA 40-pin interface cable:
If you are using a standard 40-pin two-drive ribbon cable, plug one connector into J1 on each drive and attach the remaining connector to the host adapter. Align pin 1 on connectors as described above for a one-drive system.
Two-drive system using interface cable supporting cable select:
If in step 5 on page 2 you followed the instructions for two drives and cable-select, you must assign master and slave status to drives by the following method: to make a drive the

master, attach it to the connector that has the CSEL signal line connected to pin 28. To make a drive the slave, attach it to the connector that has pin 28 unconnected (open). Finally,
