Edb Database Page Read Failed Verification Because Of No Page Data

Microsoft Exchange Server administrators come across various Exchange database related errors on a regular basis

. Often these error messages make the life of these administrators miserable. Situations become serious when administrators come on the verge of huge amount of data loss. The data loss situations are often faced by administrators when the Exchange Server database (EDB) file gets corrupt.

An EDB file gets damaged due to various reasons such as improper server shutdown, malicious virus, physical damage of storage media etc. At times, when Exchange Server database file gets damaged, MS Outlook cannot access users email, calendars etc from it which further makes the situation difficult to handle. Additionally, the communication amongst the users is on a halt, which may also lead to delay in timely projects as information related to the projects cannot be shared. At this point of time, one big question for administrator is how they will restart communication as early as possible. Because to restart the information sharing and communication, administrators need to repair exchange database and rebuild the Exchange database which might result in data loss.

Corrupt Exchange server database stops and fails to mount. However, you can repair Exchange database using eseutil utility to perform Exchange database repair. If this utility fails too, then you will be compelled to utilize the latest updated backup copy available or repair Exchange database with an EDB repair software. For example, you might come across an error message given below dealing with Microsoft Exchange Server:

Database page read failed verification because of no page data.

This situation further suggests you to move the existing Exchange Server database to a new hardware. The error is logged with event 376 in application event log. The above mentioned error clearly depicts that the database read operation has failed. Now the causes behind the occurrence of this error message are mentioned below:

Specific Database page that has been referenced within the database file is supposed to be in use, but Exchange finds it empty or uninitialized.

The page might have failed its checksum test with error-1018. But if the page number field that is in use is 0x00000000, the checksum failed page will show -1019 error instead.

File is corrupt and as a result, it maps some pages into database file that are not associated with it.

Logical links or pointers between database pages are incorrect

Event 476 can also be related to -1018 error that indicates checksum mismatch and is caused generally due to hardware issues. Check your system for related hardware issues if the database corruption persists. Replace the hardware and upgrade your firmware and /or disk controller if needed. However, to repair Exchange database, you can run eseutil/p command which is a hard recovery option in Exchange database. But it is recommended that you use Exchange database repair third party tool to repair EDB files without causing any damage to database content, metadata or structure.
