Question : Restoring SQL server .MDF file, without .LDF file (cannot load database)

I have backed up MDF file with Veritas/Symantec backup. And now - i have MDF file only restored (backup does not contains LDF file). MDF file is ~15GB.

Now - I cannot get database working. Main issue and error from server is:
"cannot be opened due to inaccessible files or insufficient memory or disk space".

When I try to deattach/attach another 15GB MDF file (working now) everything is going ok.

Database is from Sharepoint server. Running MS SQL server Express 2005.

Answer : Restoring SQL server .MDF file, without .LDF file (cannot load database)

OK, resolved problem! :)

First, the problem with
"cannot be opened due to inaccessible files or insufficient memory or disk space".
was just a file access permissions! I changed permissions, and got DB into Emergency mode.

Second - recovery of DB was needed because deleted files from Sharepoint server. I forgot, that Administrator can just restore files even deleted from RecycleBin. So, restored files from current DB.

Guys, let's make good backups anyway! :)
