It does.

You are correct that grub numbers from zero, but that message is
coming from the kernel on the /boot partition, not grub.

I can boot the SuSE 7.3 system I have on my /dev/hdb disk and mount
/dev/hda3 on /mnt. I don't need that old 7.3 system, and I intend to
install SuSE 8.2 on top of it to get mostly back to where I was.

I've mounted the /var partition and looked at the /var/log/messages
file, but there is nothing suspicious in there. Specifically, no disk
I/O errors reported.
