IIRC, grub only writes to the first few kilobytes of your drive, which
is not in any partition or data area, so that is very unlikely to be the
problem unless you're using an extremely old version of GRUB 1 which
can't handle large drives.

I have already given steps on reproducing the problem. Once the problem
is there, it stays there no matter how many times you try to install.
The only way to stop the problem once it's there is to physically zero
out any left over file systems on the disk. This shows that it indeed a
problem with the left over file system. It also proves that it's not a
GRUB problem because if it were, the problem would continue because all
you did was zero out a file system which no longer existed in the first
place. I'll cut you some slack on this one, because I didn't mention in
my previous posts how I fixed the problem.
