Updated: 01/24/2018 by Computer Hope

When inside a computer, ensure you are familiar with ESD and take the necessary steps to help prevent it.

Hard drive not connected properly

Verify that the cables are properly connected to the back of the hard drive. All hard drives have at least two cables connected to the back of the drive. Verify that the power cable is connected as well as the interface cable. Note: the interface cable must also be connected in the correct direction. Users who have IDE/EIDE hard drives, pin one (red or blue edge of the cable) points towards the power connection.

IDE cable

Next, verify that the interface cable is properly connected to the interface card or motherboard.


if the cables appear to be connected properly, consider disconnecting and then reconnecting the cables to ensure they are firmly connected.

Hard drive not set up properly

If a new IDE or EIDE device has been connected to the computer, ensure that the jumpers are set properly.

Verify that the computer hard drive is being properly detected and set up in CMOS setup. If your CMOS supports "Auto," we recommend that it be used. Note: if the hard drive is not being detected by the CMOS you have one of the problems below.

Bad hard drive cable

If the above recommendations have been attempted and you are still encountering the same issue, the cable connecting the hard drive may be bad. Replace this cable with a known good cable.

Bad hard drive

If you continue to experience the same issues, the hard drive may be bad. We recommend that the drive be replaced. If the computer or hard drive is still under warranty, it is recommended you contact the computer manufacturer of the hard drive or the computer for additional recommendations or replacement.

Bad interface board or motherboard

Finally, if none of the above recommendations resolve your issue, unfortunately it is likely that the interface board the hard drive connects to or the motherboard is bad. It is recommended that these components be replaced or that the computer be serviced.

If the computer or the motherboard is still under warranty, it can likely be repaired or replaced. We strongly recommended that you contact the hardware manufacturer for additional information.
