What I have learned from Google searching:
With MyISAM tables you can simply copy the FRM, MYD, and MYI files. In the folder for the DB I'm trying to recover, there are only FRM files and a "db.opt" file, so they must not be MyISAM tables.
My computer crashed, but the data is still on the hard drive. The MySQL 5.5.8 server was installed with WAMP on the crashed computer.
I have tried copying the entire data folder over, but MySQL only creates a blank database - no tables.
There is an FRM file for each of the tables I wish to recover. However, they are not readable text files. Is there any way to recover the table structure from these files?
This post http://stackoverflow.com/a/7688688/1188138 indicates that the structure is in fact in those files, but does not provide a method of retrieval.
Thank you so much - I have tried everything I can think of.
