Either the drive is defective, the jumpers/ cabling are set wrong, or you have a defective cable.

This assumes the drive is an IDE/ATA type and not a SATA type.

Do you have a physical hard drive connected to the Primary Slave connection ?

If the answer is NO, then the message is NORMAL for some bios versions when you have the setting Pri Slave = AUTO in the bios.
If you don't want to see that message, set Pri Slave = NONE or similar in the bios.

If the answer is yes, you DO have a physical hard drive connected to the Primary Slave connection, there is probably something wrong with the data cable connection of the drive,or you may not have the power connector plugged into the drive, or if it's an IDE drive you may have a jumper on the back of the drive set wrong .

It is common to un-intentionally damage IDE data cables, especially while removing them - the 80 wire ones are more likely to be damaged. What usually happens is the cable is ripped at either edge and the wires there are either damaged or severed, often right at a connector or under it's cable clamp there, where it's hard to see - if a wire is severed but it's ends are touching, the connection is intermittent, rather than being reliable.
Another common thing is for the data cable to be separated from the connector contacts a bit after you have removed a cable - there should be no gap between the data cable and the connector - if there is press the cable against the connector to eliminate the gap.
80 wire data cables are also easily damaged at either edge if the cable is sharply creased at a fold in the cable.

Try another data cable if in doubt.

80 wire data cables must have the proper end connector connected to the mboard IDE header - usually that's blue, but in any case it's the one farther from the middle connector on a 3 connector data cable.

Check your SATA data cables. The connector on each end should "latch" into the socket on the drive and on the mboard, or on the drive controller card - it should not move when you merely brush your hand against it near the socket - if it does, mere vibration can cause a poor connection of it - use another SATA data cable that does "latch", or tape the connector in place.
(There is a slight projection or bump on one side of the outside of the connector that "latches" it into the socket - it's easily broken off or damaged)

The same thing applies for the SATA power connection.
