New HDD not detected in BIOS

July 31, 2012 at 06:32:47
Specs: Windows xp/7
HDD not detected by computer. I have an XPS 400 which was running windows XP. The original HDD crashed and was never able to load again. I have purchased a 500 GB Seagate Barracuda HDD which I thought all I had to do was plug in where the original HDD was but it isn't detecting the HDD at all. To this new HDD I would like to install windows 7, but since BIOS is not detecting the HDD, I can't install anything. I have tried to install windows XP plus I have tried to load drivers, RAID and other third party items; but still no can do....

If the HDD isn't being detected by the BIOS, either the drive is defective, it wasn't connected properly, or the controller isn't enabled.

Hi vivers,
Welcome to the community.

As you said that you have replaced the hard drive which is not detected in bios, kindly follow the below steps:

1) Try connecting the hard drive to different SATA ports on the motherboard.

2) Swap the hard drive data cable with the DVD drive data cable and check if the hard drive is detected.

After each steps verify if the hard drive is detected in BIOS.

Waiting to hear from you.

Thanks & Regards

Bad Drive.
Bad power or signal cable.
Incorrect BIOS settings.
If PATA, incorrect Jumper settings

OR your original problem was NOT really a bad hard drive but another uncorrected problem that you will not have to diagnose.

You have to be a little bit crazy to keep you from going insane.
