would be the chipset's SATA controller driver although since the Windows 7 installer has most SATA drivers
, this error can mean other things including a bad ISO download or burn. If you burned DVD, try burning another at 4x speed using ImgBurn.
You can try downloading SATA driver from Samsung's Support Downloads drivers webpage for your model, unzip to stick or CD to insert. See if HD shows up then.
Make sure you have the latest BIOS update, if so reset the CMOS: http://pcsupport.about.com/od/fixthe.../clearcmos.htm
Set SATA controller in BIOS setup to AHCI first, then IDE mode if necessary.
But if you use a flash stick to install, it may bypass the error altogether. Install UltraISO trial, on File tab Open the ISO, on Bootable tab Write Disk Image, Format button, Write button. Boot under USB or HD's in one-time BIOS Boot Menu.
If you have store bought Windows 7, extract the ISO using ImgBurn.
