Primary file is full

We set the database to : automatically grow file, unstricted file growth, grow by 10%.
As I understand it will automatically grow, why we recieved error message like primary file full.Not enough disk to grow another ten percent?

-PatP|||Thanks, But we do have enough space.|||How big is the datafile now? And is it sitting on a volume that is formatted with FAT32 or NTFS?|||We set the database to : automatically grow file, unstricted file growth, grow by 10%.

How about, like, the actual error message...|||Thanks,

What I want to do now is to set an alert that when the database file is 90 % full, not log file, then send an email.

I didn't see there is an alert like this in the sql event alert, do I need to define it, can I do it in EM?

Also wondering when the system extended the database, when it's full or when it has some percent left?

Thanks|||Search on the term "autogrow" in Books Online, and you should find this in an article titled "Physical Database Files and Filegroups":

SQL Server 2000 files can grow automatically from their originally specified size. When you define a file, you can specify a growth increment. Each time the file fills, it increases its size by the growth increment. If there are multiple files in a filegroup, they do not autogrow until all the files are full. Growth then occurs using a round-robin algorithm.
