What is SQLite3 Disk I/O Error in Cocoa

I am programming in snow Leopard 10.6. My application opens up a locally stored database successfully, but when it tries to insert into the database, I continue to receive 'Disk I/O error". Anyone has any ideas as to what could possibly cause this?

Thanks Yang

+2  A: 

From sqlite.org:

SQLITE_IOERR

This value is returned if the operating system informs SQLite that it is unable to perform some disk I/O operation. This could mean that there is no more space left on the disk.

This could be one reason. Another could be insufficient rights (maybe the db-file is write protected?).

HTH, flokra
