1780 or 1790 hard drive error at boot

By
Values have been recently changed

If the hard 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 drive verify the values are properly set within the DDO and re-setup the DDO with the DDO diskette, usually provided with the hard 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 drive.

Cables loose or not connected

Verify that the data and power cable are connected to the hard 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 drive, motherboard, or interface board is bad. It is recommended that the hard drive be replaced first.

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