[FONT=&quot]1-My os Windows Vista Premium 32 bit: My Motherboard Asus P5K-E WIFI AP, 4 GB Kingston Ram, İntel 180 GB 335 series SSD, 1TB HDD Western Digital, 2 TB Toshiba HDD, Gpu Radeon HD6850, Cpu intel quad core [/FONT]
[FONT=&quot]2-In AHCI mode bios and Windows detected İntel 180 GB SSD and 1TB Western Digital, 2 [/FONT]Tb Toshiba. But in ahcı mode Windows not detected 1 Tb Western Digital on my os not appear.

3-In IDE mode bios and Windows detected İntel SSD, 1 TB Western Digital and 2 TB Toshiba .all drive work fine.[FONT=&quot][/FONT]

My recommendation would be to stay in IDE mode. The performance gain with AHCI is minimal anyhow. I run my Vista systems (all have SSDs) in IDE mode with no problem.
