Installing the drive in Mac OS X systems

1.Install the drive in your system using the instructions provided on the front of this installation guide.

2.Insert the Mac OS X Install CD 1 (OS 10.3 and earlier) or Install DVD (OS 10.4). These operating system discs are provided by Apple and nor- mally ship with Apple computers.

3.Restart the computer while holding the C key (you can release the C key after you see the Apple logo appear on the screen). In Mac OS X 10.4 or later, you must select your language after booting from these install discs.

4.If the new drive you just installed is the only disc in your system (replac- ing the original hard disc drive), click on “continue” and follow the on- screen instructions to install OS X on your new drive.

5.Select the drive you want to install in the left panel.

Warning. Be sure to select the correct disc before erasing the drive. Just as the name implies, erasing erases all data on the selected drive.

Note. If you are installing the drive in an Apple G5 system and the system does not recognize the drive, contact Seagate Technical Support using the phone number for your region listed in the “Seagate support services” section in this installation guide for information about com- patibility with Apple G5 systems.

6.Click on Erase and then select a volume format (Mac OS Extended is a commonly-used format), type a name of your choice in the Name field, and click on Erase again. Confirm your intentions by clicking Erase once more to begin formatting the drive.

Windows Troubleshooting

If your drive is not working properly, these troubleshooting tips may help solve the problem.

1.Does the drive spin up? A spinning drive produces a faint whine and clicking noise. If your drive does not spin, check that the power connec- tor and interface cable are securely attached.

2.Does the computer recognize the drive? Verify that the drive is enabled in the system CMOS or setup program. If not, select the autode- tect option and enable it. If your drive has a problem, it may not be rec- ognized by the system. If the operating system does not recognize the drive, you need to load your host adapter drivers.

3.I receive a “drive not detected” message. Why? Your SATA-equipped motherboard or host adapter may use a chipset that does not support SATA speed autonegotiation or other 3 Gbit feature. Install a jumper as shown in the following illustration to limit the data transfer rate to 1.5 Gbits per second and enhance compatibility with some computers.

4.Does Scandisk find the drive defect-free? Scandisk is a utility located on your Windows startup diskette that scans the drive for defects. If defects are detected, this may be an indication of a problem.

5.Why does my computer hang on startup? Verify that your system is SATA compatible. You need either a SATA 1.0-compatible motherboard

connector or Serial ATA host adapter to use this drive.

6.I’m running Windows 98 and FDISK is not reporting the full capacity of my drive. Why? You need to upgrade your version of FDISK if you are using the diskettes or CD that came with your original Windows 95 or 98 operating system. Microsoft provides a free downloadable FDISK upgrade. See Microsoft Knowledgebase article number 263044 located at http://support.microsoft.com.
