Hi, 1. First please refer to the article below to check the issue. Event ID 9519 "Error 0x80004005" is logged in the Application log when you try to mount a database in Exchange Server 2007 http://support.microsoft.com/kb/925825 2. Please check the driver for the Raid controller. You may update the driver. 3. Please try to disable or uninstall any anti-virus application on Exchange Server. If problem still persists, then please try to follow the steps in article below perform a dial tone recovery.

After that, I recommend you to backup the database and perform database repair on the copy. Besides, if you have daily backup, then I recommend you to restore the database. Regards, Xiu
