hard drive not recognised at system start up

  dripv 13:10 09 Oct 2006

I have three SATA hard drives ininstalled in my PC.

Occasionally one of them is not recognised at start up and so I cannot access any data on that drive.

I restart (sometimes a few times) and the drive is recognised again.

Any help to understand and sort out this problem would be gratefully received.

It may be slow getting up to speed, and so the POST is missing it.

You could try setting (in the BIOS) the "Quick Memory Test" to "Disabled". This runs a longer (and better) RAM test, which allows drives more time to start up.

You could also try swapping over the power and data cables between drives, and see if that affects things - bad cables, and poor connections can also cause similar symptoms.

dripv are you running any form of Raid system?
If no Raid then check in the Bios that the SATA Mode is set to IDE and not SATA. (look in Integrated Peripherals section).

DieSse's advice is excellent.

I disabled the "Quick Memory Test" and the third drive was recognised on the next reboot.

I am not running a Raid system.

I will keep my fingers crossed but it looks like youre advice has solved my problem.

Thanks for your help.
