Troubleshooting
If your drive is not working properly, follow these troubleshooting steps.
1. Does the drive spin up? A spinning drive produces a faint whine
and clicking noise that begins when power is applied. If your drive
does not spin, check that the power connector and interface cable
are securely attached and the jumpers are installed correctly.
2. Does the computer recognize the drive? Verify that the drive is
enabled in the system CMOS or setup program. If not, select the
autodetect option and enable it. If your drive has a problem, it may not
be recognized by the system.
3. Does FDISK detect the drive? Run the FDISK program located on
your Windows startup diskette. Type fdisk/status to verify that
your hard drive is present.
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 won’t the drive format to full capacity? Verify that your BIOS
has autodetect and LBA mode enabled. Otherwise you may need to
use Disk Manager to achieve the full capacity of your drive. Download
the latest version from www.seagate.com or find it on your CD.
6. The computer hangs on startup. Verify that your system is
ATA/100-compatible with the UDMA mode setting. Some legacy BIOS
cause hangs on startup or other problems if not ATA/100-compatible.
For more information, see the earlier section on the Ultra ATA/100
requirements. In addition, some legacy BIOS may cause a hang due
to the large drive capacity. Consider using the alternate capacity
jumper if it is available on your drive model.
Use the alternate capacity jumper if your computer does not support
higher capacity drives. The jumper will limit the 80-, 60- and 40-Gbyte
drive capacities to 32 Gbytes.
