|If you are going to use the 2TB external on a laptop then why are you worried about getting it to work on the Abit board? |
Have you watched the POST screens to verify the 2TB drive is not being configured by the BIOS? There may be an issue with your SATA I controllers and the SATA II hard drive. You may need to place a throttling jumper on the 2TB to slow it down to SATA I speeds. Also, there may be an option in the BIOS to delay the time given to configure the hard drives. The maximum time is usually 5 seconds.
Some high performance hard drives will not work on SATA I controllers at all.
