Toshiba F30 not detecting HDD

My Toshiba F30 (PQF30A-02400M) is not detecting the HDD. I accidently put in to the sleep mode and when i rebooted it came up with a system fault by not detecting the HDD I have tried to repair useing the windows disks but still can't detect the HDD I have pulled both my HDD out and connected them to another computer and they work fine.
When i go into the setup of the Laptop it states that both the drives are online and shows the size of both of them.
the only drives it is showing is a X drive which is the boot drive and the vd drive.

Can anyone give me any idea what is wrong with this Laptop. :4-dontkno

i am running Windows Vista .

thanks
