Retrieve lost data MyISAM table mysql how-to

Hi!
 i lost 99% of all my data from 2 tables of my database.

I ran a myisamchk and push the info to a txt file. I got this:
Data records:       1   Deleted blocks:     252
- check file-size
- check record delete-chain
- check key delete-chain
- check index reference
- check data record references index: 1
- check record links


I need to retrieve the deleted blocks since it shouldn`t have been deleted and don`t know why it is in deleted blocks.

Any idea what should i do?

Have you done a

myisamchk -o table ? or a
myisamchk -r table?

This should be able to recover data

Both of these commands doesn`t work.

Actually, it looks like i would have done a DELETE command, since my rows seems to appear in the Deleted blocks. An optimize table clear DELETED BLOCKS to make more space... but what i want is to retrieve data that would have been deleted earlier... but the thing is, we didn`t do such command.

Also, when running myisamchk, i don`t get any info telling me it is a corrupted table.

Any other idea?

Last try would be...

Do you backup your data? If you have a  latest backup then you can restore.. you may end up losing couple of hours data...

For point in time recovery...
Is binary logging enabled???? If so then you may give try like this..

Pls do the change as required..

mysqlbinlog --database=db_name --start-date="2008-10-23 9:00:00" \
      --stop-date="2008-10-24 10:05:00" \
      /var/log/mysql/bin.xxxxxx \
   > /tmp/mysql_restore.sql

I didn`t have a backup that is why i needed to try to restore those blocks.

I haven`t been able to retrieve them so far and now i am making backup since i lost alot of data from those 2 tables.
