问题
A very important database has gone corrupt that was sitting on server at a shared web host, and I didn't back up. The table contains a large list of very important email addresses. I can get a table listing, but if I open any of the tables with Navicat or phpMyAdmin, I get the following error:
Incorrect information in file: './the-table-name.frm'
I was able to get a hold of the .frm files associated with the database from the web host.
There is other data in there, but if I could at least get the email addresses, I would be alright.
How do I recover this database? I would be willing to pay somebody to fix this.

This belongs on serverfault.
First, .FRM files contain none of your "data". They are simply the definition of the table.
If all of the following are true:
- The table is using the MyISAM storage engine
- You know the
CREATE TABLEstatement required to recreate the table
Then, do the following:
- Stop MySQL
- Backup your table_name.frm, table_name.MYI, table_name.MYD files
- Delete them from your mysql data directory (/var/lib/mysql usually)
- Start MySQL
- CREATE the table again
- Stop MySQL
- Copy the .MYD and .MYI files back into the datadir, replacing the ones there.
- Start MySQL
- ???
- Profit

I had a similar issue, it turns out the MySQL InnoDB engine was turned off (I was able to check via phpMyAdmin, a bash pro could tell you how to do it other ways). in my case, it was a simple as restarting MySQL, but you may want to check your config if something changed there.

You may try the following commands: CHECK TABLE tablename
If this gives "corrupt" message try:
REPAIR TABLE tablename
Actually these are didn't solve my similar problem but they may be useful for somebody.
