Hard disk not detecting

It is very likely that your motherboard is not capable of handling large HDDs. Too bad, friend. Use a smaller one, or may be two of them.

This board is a fairly new board withe serial ATA so I would imagine it should be able to handle a 160 GB hard drive. Check your connections to the hard drive and make sure they are fully seated. Also make sure the power connector going to the drive is fully inserted and working. If you have another serial ATA cable swap it out maybe the one installed is defective. Make sure the serial ATA function is activated in the BIOS and that it is listed on the boot menu. If the hard drive is brand new you may have to create a partition on the hard drive in DOS in order for it to be recognized by the BIOS. You may have to make a boot disc on another computer and run the DOS program to create a partition on the drive and then format the drive.
