My suspicions about the motherboard are correct. It doesn’t recognize the new drive unless I use the alternate jumper settings to fool the BIOS into thinking the drive is a different size than it really is. That’s not a big deal, but the drive documentation says not to use the alternate jumper setting with Windows NT or 2000, which I am running. Windows 2000 recognizes the drive as 7.87 Gb no matter what I do, probably because I’m using the alternate jumper setting. I could flash the BIOS of the motherboard, but the board is so old that no one supports it any more.

Looks like I need a new board. Convenient for the computer industry, eh? Oh well, it will be a while before I get the server running the way I want it to, I guess.
