Can't Detect Hard Disk

Dear Sir,

I just had this T320 and my problem now is i dont have any cd's, drives, manuals, etc. coz they shipped this from china. I tried to follow all instructions but failed to find the 2 500HDD installed (Dell Constellation).

Please help me to run the system.  I tried ATA AHCI RAID and so on but failed to detect the hard drive.

Thank you for all your support and regards to all.
