You can also create a dummy database with the same name as your original database, shut down sql server service and overwrite your data files with original files. Restart sql server service, It'd recover the data you had in the original database.
This is more of a cowboy way (e.g. not a supported way, but it works). In order for it to work you also need to create the dummy database's files with the same name as the LDF, MDF and NDF files that you have.
Personally I used it only once few years ago when I needed to attach a database that was detached while it was in suspect mode. Since the database could not be attached, I used your approach. In all other cases, when I can attach the database in the normal way, I don't see any reason to use this method.
