My MBR is not the problem....I have a copy of that, and infact already
restored it. It's the logical partitions in the extended partition that I
am missing info on. Since I deleted the extended parition though fdisk, I'm
pretty sure the logical info got wiped, and even with the correct MBR, fdisk
does not pull any logicals up. The data is all there, and if I *really*
needed it, I could start scanning the raw drive for the bootsectors to find
where they start.
But the OS, some where, has the layout of the logical partitioning. If I can
get the start/stop sectors I can fix it in 30 seconds.....
I normally keep all this info on a peice of paper, along with copies of all
my boot sectors....I just haven't gotten around to that yet with this
set-up.
