Issue:

1780 or 1790 hard disk error at boot.

Cause:

This issue could be caused by any of the below reaons.

1. Configuration values have been recently changed
2. Jumpers not set properly
3. Cables loose or not connected
4. Bad hardware

Solution:

Configuration values have been recently changed

If the hard disk drive values have been recently changed or adjusted either through hardware or software: If you are utilizing a DDO (Disk Drive Overlay), to detect a hard disk drive verify the values are properly set within the DDO and/or re-setup the DDO with the DDO diskette, usually provided with the hard disk drive.

If a DDO is not being utilized, verify that the values are properly set within CMOS. If CMOS is setup as Auto this should be sufficient.

Jumpers not set properly

Verify that the jumpers are properly set on the hard disk drive.

Cables loose or not connected

Verify that the data and power cable are connected to the hard disk drive. If the cables appear to be properly connected, disconnect the cables and then re-connect the cables to ensure they are not loose. In addition, verify that the data cable is also connected to the motherboard or interface card.

Bad hardware

If all of the above recommendations have been completed and the computer continues to experience the same issues, unfortunately it is likely that the hard disk drive and/or motherboard/interface board is bad. It is recommended that the hard disk drive be replaced first.

If the computer is under warranty contact the manufacturer of the computer or hard disk drive for replacement.
