Either the superblock or the partition table is likely to be

because of problems like this. I make a backup of the partition
tables of all my disks
dd if=/dev/hda of=machine_name.mbr bs=512 count=1
handy if you're multibooting and need to restore the original mbr
sfdisk can also be used to make a copy of the partition table:
To save the partition table:
sfdisk -d /dev/sda > /etc/partitions
To restore the partition table:
sfdisk /dev/sda < /etc/partitions
Adjusted for your devices and desired file location, of course.
This is also useful for setting up raid disks.
