Attach database fails

Folks, i had a database with data and log file on seperate disks. After reboot, i've lost the log file; now i am trying to attache the data file using EM and QA, i get the following error; plz guide:

sp_attach_single_file_db 'production', 'd:\production_data.mdf'

Server: Msg 1813, Level 16, State 2, Line 1
Could not open new database 'production'. CREATE DATABASE is aborted.
Device activation error. The physical file name 'D:\production_log.LDF' may be incorrect.

Howdy!try this...creat an empty database with that name...then detach it, and then try you attach|||Hi Brett, same error. If i give the logfile for newly created database(as u suggested) i get the error can not associate files from different databases.

Howdy!
