hi, I just upgraded to a new motherboard and when I enter the bios the primary ide master, a 160 gb hard disk is shown as not detected. It I select auto detect it recognizes it as wdc 1600... so that seems ok but when I go to boot sequence it is not listed. Tried another hard drive and it detects ok and is listed in the boot sequence but it is an 80g smaller one. I put the 160g back in the old computer and it works fine so I know the 160 hdd is good and the connections are good. Is this new motherboard faulty or is this some sort of bios problem? thanks

"I just upgraded to a new motherboard"

Which HDD were you using with your "old" motherboard?

Double check the jumper setting on the back of the HDD. WDC drives usually have different jumper configurations for master (single) & master (with slave). There *should* be a diagram on the label.

BTW, you're most likely gonna have to reinstall Windows due to the board change.

Without more system specs it is hard to say but you might look for a second setting in the BIOS for WHICH harddrive to use in the boot order. Many newer BIOSes have such a selection. It may even be on a different screen.

thanks to all for you help. that was it. I overlooked the fact that I had two drives on one ide channel in the old computer and therefore had the drive jumper set to master with slave, moved the jumper to single drive and all is good. thanks again for your help.
