The only time I've seen a partition table disappear was once and it was
because there was a physical defect within the hdd. The only defense against
shoddy hardware's below average MTBF is backups. dd, tar, cpio, amanda or
whatever are your friends.
Keep your metadata (fstab and such) is a secure place on read only media such
as a CD. And when the hdd dies, use the metadata to lay down new partitons on
the replacement disk and then restore with the backups. It may take half a
day to do a full restoration (once you get the new hdd), but it's time well
spent IF you prepared correctly.
