I have recently upgraded my PC from vista to windows 7 and that to f the 32 bit windows vista to 32 bit windows 7. In vista the Intel storage manager disk drivers where used as the source of the drivers. Now as I am using the windows 7 so in the windows 7ís Device Manager, I observe the standard "Disk Drives" division and they were saying that "ST3250410AS ATA Device" for each of the drives. Now the thing here is that I confused regarding the drivers which were earlier present in my system and which are present now they are altogether different. Please help me knowing the difference between them Windows 7 native AHCI drivers and Intel RST drivers and also let me know which one is the better.
