Just received question from one of the DBA
Question: I do not have full backup of my database. My .mdf and .ldf are corrupted. Is there any way I can restore database now?
Answer: Sorry. I do not think there is any way you can do it. Try attaching this files to database using db_attach but if that does not work, it will be very difficult make it work.
If any of blog reader know fix for this, please post here.
