Can you confirm the database is a pure 2008 R2 database? That is, not upgraded from an earlier version, etc. Is it a test database (that I might potentially get a copy of) or a production one?

Hi Mark,

The database is a pure 2008 R2, I created it from scratch in 2008 R2. But it is about 60 GB and I can't upload it but can do some tests or give you remote access via Teamviewer if you tend.

Regards, Afshin Hamilton

I have forgotten to say that it is a corrupted mdf file. Now I can not attach it to SQL Server.

Ah, that explains it then. Currently OrcaMDF will only read functional MDF files, all corrupt files will basically yield an undefined result. I've done some experiements in the corruption and thewalkingdead branches, but neither are functional or automatic. OrcaMDF may read parts of corrupted MDF files, but it will require you to code the reading manually to extract just the parts you're interested in, without having OrcaMDF parsing the whole base table structure for metadata.
