Dave -
Can't really tell you where grub was originally. I would have thought that
/dev/hda and /dev/hda1 both pointed to the same area i.e. the beginning of the
first disk. Looking at the results of your requested commands, I guess
I've already learned something new since they show different results.
I've attached the output of the fdisk -l and sudo command output. Ignore
the third disk, its a disk that I just hooked up that's empty.... space for me
to copy if that's my only option. If I must do the copy, as I can't seem to
view the vfat files with windows, do you have a suggestion as to how best to
copy using Linux?
Thanks for the help.
Gary
