No hard drive

Hi,

my specs:

1. Gigabyte Ma770t-Ud3p
2. AMD X4 620
3. SB770
4. ATI HD4850 1GB RAM
5. Realtek ALC888
6. SAGEM XG-760n Wi-Fi dongle
7. HDD: Samsung (SATA, Windows 7 installed) AHCI, WD (SATA) AHCI
8. mouse, keyb. - USB

Hi, I've got a problem installing 10.6.3 Retail on my PC. The disk that I want to istall SL to is not seen in Disk Utility during installation(WD 80GB SATA, working with no problems on WIndows) ImageShack® - Online Photo and Video Hosting although it's seen in System Profile ImageShack® - Online Photo and Video Hosting

SL installation recognises other disk(i've got no problem installing system on it) so it isn't matter of drivers. I've tried many methods, DISKPART, Gparted, i've done even a Low Level Format, but it doesn't work. Is there any possibility to force this disk to work with installer? Is there any Terminal command thaht allow to check why it's not working?

Sorry for my bad English.

Thanks for any advice

Cheers
