Maybe... Maybe the sequence and timing of creating files and rm'ing files, etc, is such that the .par and .frm fail to get created. I would consider this to be a bug ( bugs.mysql.com ) in that it can "lose" data rather than gracefully aborting. For many actions, such as an ALTER that copies a table over, the sequence is such that a machine crash or out-of-disk will leave the original table intact -- better than losing stuff.

Grrr... So many problems are caused by sloppy work by "3rd party" vendors. You should be bugging them, too.
