HDD Configuration Checks

While booting up the system, observe the BIOS's HDD type information displayed on the monitor. Note the type of HHD that the BIOS believes is installed in the system. The values stored in the CMOS memory must accurately reflect the actual HDDs format installed in the system. otherwise an error occurs. Possible error messages associated with HDD configuration problems include the Drive Mismatch Error message and the Invalid Media Type message. You can access these values for change by pressing the Ctrl and Del key simultaneously, during the bootup procedure.




























If the HDD is used with a system board mounted controller, check for the presence of an HDD enabling jumper on the system board. Make certain that it is set to enable the drive, if present. Check the drive to make sure that it is properly terminated. Every drive type requires a terminating block somewhere in the interface. On system level drives, check the master slave jumper setting to make sure that it is set properly for the drives logical position in the system.

If you have more than one device attached to a single interface cable, make sure that they are of the same type. Mixing device types will create a situation in which the system cannot provide the different types of control information each device needs. The drives are incompatible and you may not be able to access either device.

If the drive is a SCSI drive, check to see that its ID has been set correctly and that the SCSI chain has been terminated correctly. Either of these errors results in the system not being able to see the drive.Also check the CMOS setup utility to make sure that SCSI support has been enabled, Along with large SCSI drive support.
