change your disk, it looks as if it is broken. You can visit the website of the disk company and check if it is still in waranty.

Hi,
Another trick relates to loose power contact pins. Gently insert a small instrument screwdriver into the power plugs, between the metal socket and the plastic housing, to slightly bend (close up) the socket.

Does your Bios support the Hard drive size? Some older bios can't read the new bigger hard drives and sometimes you can flash the bios with a newer version to support the drives.Have you checked that the jumper settings are correctly placed for the config you are using on the drive (Master, Slave, Cable Select)? Next I would check the bios settings for the drive, most have an autodetect for the hardrive. When you enter the bios setup see if you can autodetect the drive in there. If not then you can try and manually enter the settings of the drive into the bios setup (heads, cylinders, landing point etc..). If after al that it still doesn't work then it would seem that the hard drive is gone.

Your hard drive is dead / failing.

If it is a Fujitsu, they had a number of hard drives that had self destructing ICs on the hard drive circuit board.

Does the hard drive sound "normal" when it is spinning up?
If not, then it is very possible that the drive motor or a bearing has failed.

If the drive sounds normal and then just stops spinning, I suspect a failure of the electronics on the hard drive itself.
