Longshot...I vaguely recall seeing something like this long ago with
BIOS settings for the disk being inconsistent in LBA mode or not. I
can't recall exactly what it is, but it resulted in the system and bios
ideas of end of partition cylinder not being in sync. Naturally, windows
would correct it to its way. Has windows complained about anything and
wanted to "fix" it?
