Cable select should fix it.
I know thats what Apple recommends all hard disks be set to. Give that a try. Worked for me on my iMac 350.
I was having that issue yesterday too. The 10gb drive in my G3 iMac died, so I whipped it out and stuck an 80gig in there instead. 😀
Couldn't get it to see the drive though, figured it out in the end, cable select mode to format the HDD, Master mode to install it onto...
