grub "hide" damaged my partition table

[Joe Krahn]

I have a RedHat 7.2 system with a 40G IDE disk.
Using the grub "hide" command destroyed my partition table.
Here's the approximate disk layout:

Four primary partitions, no extended.
hda1=ext2, 4G
hda2=ext2, 4G
hda3=Linux swap, 1G
hda4=fat32, 31G

I tried "hide (hd0,3)". The command was accepted, but hda4
was not hidden. I tried hiding one of the ext2 partitions.
I think it was hda1, which contains the /boot/grub data directory,
with "hide (hd0,1)"
Now entering "geometry (hd0)" shows nothing.
No unhide commands will work.

Possible non-standard" things are the use of all four primary
partitons, no extended ones, and having a large LBA partition.
Also, can "hiding" the ext2 directory with /boot/grub mess things
up?

Grub still loads at boot time, but the menus, etc., are all gone.

Do you have any ideas of whatcould have happened?
I can try to repeat it and get a copy of the before and after
if this looks like a bug that isn't already fixed.

THANKS, Joe Krahn
