Advanced troubleshooting

If you have performed the preceding basic checks but the prob- lem has not been solved, follow these guidelines for analyzing specific cases:

The system does not recognize the presence of the drive or system error message, “No Drives Found,” appears.

∙Check all cables. Make sure they are properly connected and that the pins 1 are aligned. Make sure the cable is not crimped or damaged.

∙Check all cards for proper seating.

∙Check your host adapter’s BIOS memory address setting. Make sure that it does not conflict with another device that sets a BIOS memory address.

∙Check the drive type in AT systems. The drive type must be set to Not Installed or all of the drive-type parameters set to zero.

∙Check the Drive C partition with the FDISK utility. The partition must be active.

∙Check the bus termination. The bus must be terminated at both ends. Disable or remove all terminators between the termination at the ends of the bus.

∙Check the terminator power source jumper settings.

∙Check the power-supply specifications.

∙Reboot and make sure the drive comes up to rotating speed. (It may be difficult to hear the discs spin.) If the drive’s disc does not spin, check all drive cables.
