Help me restore by database

[Dan@TT]

Hi

I had a major breakdown of the linux server 4 days ago , yesterday however I've managed with the guys from the hosting company to recover some data from the crashed hdd.

I basically got the entire httpdocs folder , including all the forum files + the complete forum database located in /var/lib/mysql/forumname

the files located in this folder /var/lib/mysql/forumname look like this:

access.frm
access.MYD
access.MYI
....

etc.

Now the server got a new HDD, everything was reinstalled from zero. I've set up the server again from Plesk CP, created a new mysql database with the same name like the old one, same username & password to access the mysql database.

After, I went to /var/lib/mysql/forumname and put back all the previously saved files and I hoped it will work.

It doesn't work. I got Database error when trying to access the forum.

What am I doing wrong ?

Daniel
