Hi,

I am loading a 0.5GB table disabling the keys before I start loading it.  
Later on I compress it with myisampack, and needs to run myisamchk.

When I run the myisamchk I add the options --sort-index and --analyze  
Do you know if I can skip the enable keys operation?  
I was wondering if I can, since the myisamchk is supposed to rebuild the indexes anyway.

Check to see if the files are built on disk afterwards. They should be.
