I double-checked the instructions that came with the drive and it looked
like it was setup correctly as a master (there is no second HD at this
point). However, after looking looking through the box the drive came
in, and finding another data sheet, I saw a different set of jumper
settings. I tried those, and fdisk now recognizes the correct drive
size.

I don't know much about hardware, but I'm at a loss to know why there
would be two different sets of instructions for setting jumpers on one
hard drive.

At any rate, thanks very much, the jumper settings were the problem.
