Do you have ONLY the hard drive on the IDE cable? If so, or not, you may need to adjust the jumper or location of the hard drive on the cable.
Be sure you set the jumper to the correct location based on where the drive is located on the IDE cable.
CS = Cable Select = Drive can be anywhere on the IDE cable.
Master = Device needs to be on the end of the IDE cable
Slave = Device needs to be in the middle connector of the IDE cable
CS does not always work either, so if that fails use Master/Slave and ensure the device is in the proper location on the cable per what the jumper is set to. And if you are only wanting to copy over files to a SATA drive, then just use the hard drive only on the IDE cable for now, to make things easier on you.
BIOS settings that must be enabled are as follows:
Integrated Peripherals
Marvell IDE/SATA Controller (White Ports)
GSATA 8_9/IDE Controller (GIGABYTE SATA2 Chip, IDE and GSATA2_8/9 Connectors) ............. Enabled
GSATA 8_9/IDE Controller (GIGABYTE SATA2 Chip, IDE and GSATA2_8/9 Connectors) ........... IDE
And set the following if you see it near those settings
Transaction Mode ....................... Bypass
