Another option for monitoring.

As for the mysql, if you can get the raw mysql files (corrupted or not) and have a 'fresh' install of your script, you can probably surgically replace the .frm files, run myisamchk -O (safe recover) and probably get back most of the data built from the .MYI & .MYD files. Sector errors on disks usually don't wipe out too much, depending on your hosting company and the filesystem they use (probably ext3), the metadata should be there to construct the actual file chain. You shouldn't be too bad off.

Alternatively, its possible that the links are there, but, your category table that knows what the categories are is broken. So, its possible that you could repair that which would automatically allow those subpages to be created. You'll definitely want to get the software vendor contacted to see if they have any quick tricks to get you running again.
