Hi, sorry the inconveniences and the late reply... my laptop is a DV7. The model is not listed in the link but in the part 3 for ''Difficult Models'' says that DV7 are difficult to downgrade, it is possible task but needs many efforts... I have looking for SATA drivers for days in many forums but i just have found the drivers in the link of the last reply...
AMD SATA AHCI Controller: 32bit_ATI_SB7xx_RAID&AHCI_driver_v9-4_WHQL.zip - Windows Live
AMD SATA AHCI Driver from HP: ftp://ftp.hp.com/pub/softpaq/sp43501-44000/sp43839.exe
